Question

Do all plant cells have chlorophyll in them(even in a very small amount)?

Answer 1

Dear Student,

No.
Chlorophyll is a green coloured, light-harvesting photosynthetic pigment that captures sunlight which is one of the raw material for photosynthesis. It is present in green part of the plants such as leaves.
Epidermal cells of the leaf and stem lack chloroplast except for guard cells found in stomata. The root hair cells also lack chloroplast.
The underground plant cells such as roots, tubers, rhizomes, etc do not contain chloroplast because the light (important factor for chloroplast development) can not reach into the soil. They have amyloplasts that store the food as starch.
