Question

what is t.s. of chloroplast ?

Answer 1

The main role of chloroplasts is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acidsynthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsisand wheat.

Answer 2

Chloroplasts are small organelles inside the cells of plants and algae. They absorb light to make sugar in a process called photosynthesis. ... Chloroplasts also contain various yellow and orange pigments to assist in photon capture for photosynthesis.
