Plants have leaves so they can get nourishment. The process of photosynthesis, in which the plant absorbs sunlight in order to turn carbon dioxide and water into food, occurs in the leaves.Know More
Photosynthesis occurs in the chloroplasts of cells, which are located in plant leaves. Therefore, the majority of photosynthesis takes place in the leaves, making them extremely important to the survival of the plant.
During the process of photosynthesis, water reaches the leaves through the roots of the plants. At the same time, carbon dioxide enters the leaves through little openings, or pores, on the undersides of the leaves. Chlorophyll, a green pigment found inside plants, enables the leaves to absorb sunlight. The energy from the sunlight becomes the energy source that drives the chemical reaction between the water and carbon dioxide. Once the water and carbon dioxide combine, sugar and oxygen are created. The oxygen is secreted back into the air, while the sugars are stored in the plant.
During the winter, when the ground freezes, the plant's roots can no longer pull moisture from the soil and send it to the leaves for photosynthesis. As a result, the leaves stop making food and the cells no longer produce chlorophyll. The leaves then change colors and fall off the plant.Learn more about Botany
Botanists identify plants according to key characteristics such as the area in which the plant is growing, the shape of the plant's leaves, the type of bark or lack of bark and the presence or lack of fruit and flowers. Plants are generally divided into six major groups: woodland, aquatic, grass-like, orchids, ferns and flowering non-woodland plants.Full Answer >
Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.Full Answer >
Plants need water to grow because plants require internal water pressure to strengthen the stems and leaves, and plants need water to create energy. Water is also necessary for photosynthesis, which occurs in the plant's leaves with water from the stem.Full Answer >
The process of transpiration is when water moves through plants from the roots to the leaves, then changes to vapor as it leaves the plant. Transpiration cools the plant and also provides it with nutrients, carbon dioxide and water.Full Answer >
