The Plant Of A Cactus

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

When water is in short supply a plant with a closed stomata has the luck that no matter what environmental situation it’s in (extreme heat, windy conditions, etc.) it will be able to control the water that it needs from escaping regardless of the environment it’s placed in.

Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal

A plant can control its turgor pressure through its central vacuole and cell wall. If a great amount of water is inside the cell, the central vacuole will take in some of the water to take some of the pressure of the cell wall. The cell wall can also eliminate water from making its way into the cell. The would cause the cell to keep expanding, but slowly eliminate its excess

2) Stems- The main body or stalk of a plant. Most grow above ground but some grow over ground.

At the same time, we have also presented many different uses of the cacti, the contributions that they have made to both local wildlife and residents. However, these tough and useful plants are currently

The Chaparral Biome is known by various different names due to the variety of locations it is situated in around the globe. It is often referred to as the California woodland and grasslands because of it’s’ exclusivity on the Californian coasts in North America, and also known as the Mediterranean Biome due to the large areas surrounding parts of the Mediterranean Sea. The chaparrals located in California are situated in the Sierra Nevada mountain ranges, which span across to the Pacific Ocean, and cover up to peaks at 5,000 feet above sea level. Hence, due to its location the climate is often hot and dry in the summer, and often cold and rainy in the winter. Additionally, these abiotic factors affect the biotic adaptations of the plant species that are found within the Chaparral Biome.

Plants in a area may have stopped people in that area from domesticating the plants, 12 plants account for 80% of the world’s food tonnage

The chain fruit cholla plant has a sheath that is used to deter the plant from getting too hot and reflecting sunlight off of it.

Larger plants have special cells that form supportive tissues. These cells have extra thick and strengthened cell walls. To strengthen their cell walls, they produce a special carbohydrate called lignin. Lignin is the main substance that makes wood. For this reason, woody plants are said to be lignified.

Different types of organisms behave differently in their environments. They may flourish and grow well close together, or they may compete over resources. One plant may even stunt the growth of another plant by stealing all of the water and nutrients. This is known as an allelopathic effect. There are various different types of plants that have this effect on other plants.

Water- Water is required in the photosynthetic reaction. When plants lack water, their stomata close to prevent further water loss. At the same time, closing the stomata cells doesn't allow CO2 to diffuse into the leaf. Water is also therefore, linked to the carbon dioxide factor.
