Explanation:

Pollen cells are male gametophytes of seed - plants and can have spiky structures for better dispersal. Some algae have tail - like flagella for movement. The other options have incorrect associations. Pollen is not made of collagen, not found in internal organ walls, and does not help the body move. Algae are not made of axon - like bundles, not found in heart walls, and do not carry oxygen in the way described.
