Q.
Which part of the plant do not perform photosynthesis?
Photosynthesis in Higher Plants
Solution:
Photosynthesis occurs particularly in specialized cell
called mesophyll cells. These cells contain chloroplast,
which is the actual sites for photosynthesis. The cactus
stem and guard cell of stomata contain chloroplasts, so
they can manufacture food by photosynthesis. The
epidermal cells do not contain chloroplasts, so they do
not perform photosynthesis.
