Necessary to make food for itself
the pyrenoid is responsible for manufacturing starch
A pyrenoid is an organelle found in certain algae that functions in the storage and utilization of starch, a form of energy storage. It is involved in the process of photosynthesis, specifically in the synthesis and storage of carbohydrates like starch. Pyrenoids help to enhance the efficiency of carbon fixation and serve as a site for the Rubisco enzyme, which is responsible for incorporating carbon dioxide into organic molecules during photosynthesis.
Starch is typically produced in the chloroplasts of plant cells, not within algal cells. In algal cells, starch may be stored as a reserve energy source, but the production center can vary depending on the type of algae.
The correct spelling is "necessary."
Neither is correct. You say "If you feel it is necessary" or "If you feel that it is necessary."
The suffix for "necessary" is "-ary".
The correct spelling of necessary is necessary. Very simple. ( Actually it's in the question.)
