Chloroplasts, the parts of plant cells responsible for photosynthesis, are green because they contain the pigment chlorophyll, which absorbs the red and blue wavelengths of light and reflects back the green wavelengths. Chlorophyll absorbs particular colors of light to provide the right amount of energy for photosynthesis to take place. Photosynthesis is the process by which plants use the energy from the sun to convert carbon dioxide from the air into carbohydrates for food.Continue Reading
Chloroplasts are found in cells located in the leaves of plants. The chlorophyll in the chloroplasts gives the leaves their distinct green coloring. Chloroplasts develop fully when they are exposed to light.
Each chloroplast has a double layer of membranes that protects its structures. Stroma, a thick, enzyme-rich fluid, fills the area enclosed by the membranes. Layered structures called grana, which contain chlorophyll, are located throughout the stroma.
When a chloroplast is exposed to light, photosynthesis starts. The light is absorbed by the chlorophyll and converted to chemical energy in the grana. Then enzymes in the stroma begin a series of reactions which use the chemical energy to convert carbon dioxide molecules into carbohydrate molecules. The plant uses the carbohydrates for growth and respiration. Extra carbohydrates are stored for later use.Learn more about Botany
Chloroplasts are the organelles found in plant cells that contain chlorophyll and undergo photosynthesis. The chlorophyll pigments found in the chloroplasts are the main pigments utilized in photosynthetic reactions.Full Answer >
In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities integral to life, such as growth and reproduction.Full Answer >
Leaves typically have a large surface area that contains chloroplasts to absorb sunlight for the process of photosynthesis. The chloroplasts contain a substance called chlorophyll. Chlorophyll is the substance that makes leaves appear green and allows them to absorb sunlight easily.Full Answer >
Most photosynthesis takes place in the leaf of plants in the chloroplasts. The chloroplasts contain a green pigment called chlorophyll that is responsible for absorbing sunlight that hits the leaf.Full Answer >
