C4 plants differ from c3 and cam plants in that c4 plants.

The difference between C3, C4, and CAM photosynthesis is the way plants extract carbon dioxide from sunlight. This depends largely on the plant's habitat. C3 photosynthesis produces three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

CAM plants open their stomata at night, C3, and C4 open during the day.

Explanation:

the awnser is d i think

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
