Answer:
Photosynthesis is a
process which mainly occurs in leaves of all green plants. The plants have
designed their leaf in such a way that it is able to trap solar radiation and
effectively convert solar/light energy to chemical energy.
But biology is
science of exceptions. Some plants carry out photosynthesis in modified plant
parts other then leaves.
Few examples
are as follows
1.
When roots
develop chlorophyll and start photosynthesis, they are called assimilitory
roots.
Trapa and Tinospora
are the examples of assimilatory roots.
2. Stem
as Photosynthetic Organ
In Opuntia,
the stem gets modified to take up the function of leaves. It becomes flattened,
thick and
succulent and perform photosynthesis. Such structures are called phylloclade.
3. Petiole
as Photosynthetic Organ In Australian Acasia the petiole takes the shape and
function of photosynthesis because leaf lamina soon fails off.
