Summary Introduction

To write:The reason why the structure of the thylakoid in a chloroplast is well suited for its function.

Introduction:Photosynthesis is the process where light energy is captured and transformed into chemical energy. Photosynthesis takes place in two phases. Light energy is absorbed and then transformed into chemical energy in the type of ATP and NADPH.

Explanation of Solution

Chloroplasts trap light energy found mostly in the cells of leaves. Chloroplasts are disc-shaped organelles that consist of two main compartments necessary for the process of photosynthesis. The first compartment is known as thylakoid. Thylakoid is flattened saclike membranes which are arranged in stacks. These stacks are known as grana. The second compartment is known as the stroma. Thylakoid membranes contain light-absorbing colored substances known as pigments.

Conclusion

Thus,the structure of thylakoid helps the plant to capture light and transformit into chemical energy in the process of photosynthesis.
