How Does Light Affect The Rate Of Photosynthesis

In site C the data being collected throughout the 5 days showed an increase in the growth of the radish seeds. Day one stayed at 0cm because it was the starting day of the experiment. Day 2 the growth was 1 cm 9/10 cm 3/10cm 0cm 0cm. Day 3 the data showed the growth of the seeds at ½cm 0cm 0cm 1cm 4/10 cm. Day 4 the data showed 5cm 2/10cm ½cm 1cm 0 cm 0cm. Day 5 the data showed 6cm 1cm 0cm 0cm 1cm. The data is important because it shows the landfill isn't the reason why the crop failure occurred

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The diagram above shows the two stages of photosynthesis. As you can see, light is a key component as it start the light-dependent reactions which produces ATP and NADPH, which is needed in the light-independent reactions to make glucose. So without light, there is no ATP and NADPH produced and thus no glucose produced, therefore the food chain cannot be started. Glucose is also needed to make DNA and hormones for plant growth, it is also require during plant respiration. So it can be established the light is vital for plant growth and it affects the height of plants indefinitely.

Plants can absorb a number of different length light waves, although not all of them are equal in power or energy which influences a plants growth. Approximately 80% of light that reaches a leaf is absorbed and depending on its wavelength, may excite chlorophyll pigments (reference text book). Plants absorb both red and purple light waves, however because purple wavelengths are shorter, they contain more energy.

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

4.) What conclusions can you draw about which color in the visible spectrum causes the most plant growth?

Based on your data, draw a conclusion regarding how light intensity affects the rate of photosynthesis.

The relationship between the existence of gall on the goldenrod and the development on the plants by using aspect measurement at the Riverwood Conservatory Introduction This study shows that the present of the gall on the stems of goldenrod has a taller height of stems than the ones that without galls. The averaging about 4 feet (1.2m) in height, goldenrod is a perennial with clusters of bright yellow flowers. It has been used for centuries in the treatment of kidney stones, urinary tract infections, a variety of other medical condition. (1) Survival probability depends on gall size; in small galls the larvae is vulnerable to parasitoid ovipositor, whereas larvae in large galls are more frequently eaten by avian predators.

Fast plants were first routinely planted in Nepal by a farmer. Generations later, a plant explorer recognized them as brassica plants. She took seeds back to the United States and they were left untouched until a scientist was looking for a brassica plant in order to further study diseases that plagued plants of the same family, such as cabbage or broccoli. This scientist decided to use these Fast Plants because they had a much shorter life cycle than the other plant he was considering using (Williams). Instead of a year per each generation, fast plant’s life cycle is only thirty-five days long, as is seen from the image to the left. The plants usually are flowering in twelve to fourteen days (Wisconsin 1). A typical life cycle of fast plants is faster than other plants, contributing to its name “Fast Plants”. Typically, the cotyledon will appear within forty-eight to seventy-two hours, true leaves should form in four to nine days, and flowers will open in thirteen to seventeen days. By using Fast Plants, data is able to be collected quicker than if a traditional plant was to be used. However, in order to optimize growing time, certain conditions need to be met.

In this study, Plant A, which received twenty-four hours of artificial light every day, will reach the maximum height amongst all plants. Due to the maximum access of light, Plant A will therefore have the most access to energy, which is a vital source of food to the bean plant. With more energy available to the plant, photosynthesis can provide an abundance of food availability which will cause the plant to thrive more successfully.

It stated, if colors of light affect germination rate, than the Glycine max will have a higher germination rate under red

A plant is any of the boundless number of living beings within the biological kingdom Plantae, these species are considered of low motility since this species generally generate their own food by sunlight. They incorporate a large group of commonplace life forms including trees, forbs, bushes, grasses, vines, plants, and greeneries. In this task we are experimenting the relationship between light and plant growth by growing plants in three different lights which are red light, blue light and white light. As I stated above that plants generate their own food by sunlight. Sunlight can be broken up by a prism into respective colors of red, blue, orange, yellow, green, indigo, violet and white. All this lights have specific
