Question

What is the name of the cells in the leaf that are the primary photosynthetic layer of the leaf?

Answer 1

Hint: Photosynthesis occurs in chloroplasts, which contain chlorophyll in plants. Chloroplasts have a double membrane around them and a third inner membrane called the thylakoid membrane that folds into lengthy folds within the organelle.

Complete answer:
The centre part of the leaf is known as the mesophyll. The palisade mesophyll is made up of tightly packed cells that are densely packed with chloroplasts. The palisade mesophyll is responsible for 80% of photosynthesis. Gases can permeate into and out of the spongy and palisade mesophyll because the cells of the spongy mesophyll are loosely packed. The spongy mesophyll's cells have chloroplasts, but there are fewer of them and the rate of photosynthesis is significantly slower.
Plant cells are arranged in layers in leaf tissues. The three major tissues present in leaves are formed by different plant cell types. A mesophyll tissue layer is sandwiched between two layers of epidermis in these tissues. The mesophyll layer contains the vascular tissue of the leaf.

Note:
Special pigments in photosynthetic cells absorb light energy. Different pigments react to visible light at different wavelengths. The main pigment in photosynthesis, chlorophyll, reflects green light and absorbs red and blue light the most. The most important pigment in photosynthesis is chlorophyll A, although there are other kinds of chlorophyll and a slew of other light-responsive pigments, including red, brown, and blue pigments. These pigments may aid in the transmission of light energy to chlorophyll A or protect cells from photo-damage.
