Question

what are the differences between pollen and algae cells? select all that apply a pollen grains are hard tissue consisting of the protein collagen; algae consist of many cable - like bundles of axons b pollen cells are found in the walls of internal organs; algae are found in the walls of the heart c pollen cells have spikes; algae have tail - like projections d pollen cells help the body move; algae carry oxygen

Explanation:

Pollen is the male - reproductive part of seed - plants and has a hard outer layer called the exine, not made of collagen. Algae are simple photosynthetic organisms and do not consist of axons (which are part of nerve cells in animals). Pollen is not found in the walls of internal organs, and algae are not found in the walls of the heart. Pollen cells do not have spikes in the general sense described here, and algae do not have tail - like projections as a defining difference from pollen. Also, pollen is related to plant reproduction and not to helping the body move, and algae perform photosynthesis but are not primarily for carrying oxygen in the sense described for the body.

Answer:

None of the above options are correct.
