The DERMIS, especially the deep reticular layer of dermis, is composed of DENSE IRREGULAR connective tissue.
Dense regular connective tissue is composed of tightly wound fibers of collagen, mainly found in tendons and ligaments.
<span>Protists obtain food in 3 ways. They produce their own
organic molecules, ingest, and absorb.
Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a
food vacuole around the food item. Inside the food vacuole, enzymes digest the
food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place
through diffusion. Absorptive protists play a key role in decomposition. They are
considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.</span>
