Plants have many roles to play. Plants make food and oxygen, they provide shelter for animals, and they make and preserve soil, and provide useful products for humans. Plants are the only organism that is able to convert light energy from the sun into food. This process is called photosynthesis. The food that we eat is produced by plants. Humans need oxygen to live. This oxygen comes from plants. Oxygen is produced when plants make food. Animals often use plants for their shelter and their food source. Plants roots help hold the soil together and also help make soil. Plants help humans more than just the oxygen they produce. They also produce food, fibers, medicines, and energy. Animals and humans depend greatly on the roles of plants. (1) …show more content…
First off, the temperature needs to be right. If it is too high or too low it will result in abdominal development. Flowers and vegetables that grow in different seasons, require a different temperature. Warm season vegetables and flowers grow best in 60o F, 75o F, and 80o F. Cool season vegetables and flowers grow best in 50o F and 70o F. Plants require large amounts of sunlight to grow. Indoor light often does not provide enough intensity. During the hot summer months, plants need at least one half gallon of water each day. If plants do not receive enough water each day, their roots will dry out and they will die. Just like humans, plants also need oxygen to survive. They use oxygen for respiration to carry out their functions. Plants absorb minerals through their roots. They need these minerals to survive. Some of the specific minerals they need is soil, fertilizer, manure, compost, fertilizer salts. Finally, plants need support. Their basic support is soil that surrounds their roots. They also have hydroponically supports that include, strings or stakes.
Plants are a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, absorbing water and inorganics substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll (Oxford Dictionaries, 2015). Plants are the backbone of all life on Earth and an essential resource for human well-being (BGCI, 2015). For all forms of life, plants form the basic food staples. They are the major source of oxygen and food on earth since no animal is able to supply the components necessary without plants (Jennifer C, 2014). Plants make food – they are the only organisms that can convert light energy from the sun into food. Plants make oxygen – one of the materials that plants produce as they make food is oxygen gas for animals and people to stay alive. Plants provide habitats for animals – it is a primary habitat for thousands of other organisms. Plants help make and preserve soil – the roots of plants help hold soil together which help reduce erosion and helps conserve the soil. Plants provide useful products for people – many plants are important sources of product that people use, including food, fibres
This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were
All living things ultimately depend on this process. The compounds plants make during photosynthesis provide nutrients and energy to organisms that consume plants. Organisms that consume the plant-eaters gain nutrients and energy from them, so both energy and materials are passed from organism to organism.
On the outside, Mr.LaChance may not look like a gardener, but on the inside you’ll be surprised on what you will learn from him. Mr.LaChance is the garden club co- founder with Ms. Maraglio and Mr.Gonsalves, who puts their heart and soul into gardening for the children who are looking to give back to nature. Mr.LaChance gave us great, interesting information, facts, and background knowledge. He says “When you breath in the air plants give us, we say thank you, and when we breath out we say a gift for you”. Mr.LaChance says, "Without our relationship with plants, animals don't exist. Plants give us oxygen with which we break down food and get its energy. We give plants carbon dioxide as we breath out. They make sugar with that, water and sunlight. They make energy food with our exhale. Amazing, isn't it! Life is a dance of sunlight with the Earth. Plants get the first dance. We get our energy and Earth materials through plants. We have the second dance."
In an ecosystem, plants capture the sun's energy and use it to convert inorganic compounds into energy-rich organic compounds. This process of using the sun's energy to convert minerals (such as magnesium or nitrogen) in the soil into green leaves, or carrots, or strawberries, is called photosynthesis.
Plants and animals help each other every single day. For example a mouse can go up to an oak tree and take a fallen acorn, in a way the oak tree is helping the tiny mouse gather food or, fatten up for the winter so the mouse can survive through the winter or the night. According to source #3 “A hawk swoops down looking for a mouse meal. In a way, the oak tree help the hawk find it’s food.”
Plans can have two different kinds of growth: indeterminate and determinate. Plants that grow all throughout their lifetime and never reach a size limit have indeterminate growth. Most plant organs have determinate growth, which means that they stop growing after they reach a certain size. The reason that plants grow without ceasing is the presence of permanently dividing unspecialized tissues called meristems. There are two types of meristems: apical and lateral. Apical meristems are located at the tops of shoots and roots, and they enable primary growth, which is growth in length (Campbell et al., 2014). In primary growth, shoots grow upwards to try and absorb more light, and roots grow deeper into the soil to increase the surface area of the plant. Lateral meristems allow the plant to grow in thickness by a process called secondary growth. Herbaceous plants grow predominantly through primary growth, whereas woody plants use both primary and
All plants are autotrophs meaning they capture energy from different environments through a process called photosynthesis. Many plants, photoautotrophs, are a sore example of organisms that make their own food by harnessing the suns energy. Plants use the sun’s energy and convert it to chemical energy to create organic molecules to aid in ecosystem advancement. Additionally, photoautotrophs serve as a source of food for many consumers as they provide energy and building materials for cells and body parts.
Plants have different leaf sizes, colors, and shapes to adapt to the conditions of different environments, such as the arid zone, the tropical zone, and the arid zone. The arid zone has hot, dry summers and cool, wet winters, with low, scattered rainfall patterns that occur both seasonally and annually, and also long periods of time without water. Rainfall varies from year to year, and the distribution of rainfall varies between the summers and winters. During the cool, dry season, the temperature ranges from 35-45°C during the day and 10-15°C during the night; during the hot, dry season, the temperature can be up to 45°C during the day and 15° during the night. Soils can be shallow or deep, composed of sands or clays, and varies in acidity
Climate and space constraints can make it difficult to grow plants outdoors. If growing plants outside is not an option, it is important to understand what plants will need to thrive in an indoor environment. The experiment was designed to test plant growth when seedlings were exposed to fluorescent light, incandescent light, or natural daylight only. Other factors, such as amount of water, time that the plants were exposed to their light source each day, and the pH of soil were controlled in an attempt to evaluate only the light source. Two groups of plants, with 10 plants in each group, were exposed to an artificial light source from sunrise to sunset. A third group of 10 plants was exposed to natural light from sunrise to sunset. Growth
They also use trees for food and shelter. Trees support the lives of many large organisms. Trees are needed for resources to animals and more. This is why people and animals need
The first structure to appear in a germinating seedling is a root. This is so that the seedling can acquire nutrients and water from the soil as well as begin its journey to the surface for sunlight.
In order for plants to grow they require many things. They need water, nutrients, soil, air, light, temperature, space and time. Since water is vital to a plants growth, most plants use water to transport moisture and nutrients back and forth between the roots and leaves. The water contains nutrients and is taken through the roots up to the plant. Along with carbon and oxygen, that are absorbed from the air, and water which is found in soil, plants must obtain other essential elements to grow, such as nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, boron, chlorine, manganese, iron, zinc, copper molybdenum, nickel and hydrogen. The three primary nutrients plants need to grow are nitrogen, phosphorus and potassium. Nitrogen
Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms. They use carbon dioxide gas and water to produce sugars and oxygen
Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).
