Lysosomes can help break down food vesicles or can be used to recycle the cell's contents. We will talk about the reactions that make energy after Thanksgiving, but I hope that cellular respiration and ATP ring a bell. Mitochondria are double-membraned. The inner membrane is highly folded for more surface area for energy-producing reactions. Cytoskeleton , or lattice-like network of filaments throughout the cell for support.
Centrioles are microtubule structures that assist in cell division in animal cells.
Flagella and cilia . Both are membrane-bound cylinders that contain sets of microtubules, and move as a result of microtubule doublets sliding along each other. There are four animal tissue types. Epithelial tissue generally covers or lines something, and is usually separated from underlying tissues by a basement membrane. Usually see flat cells, frequently renewed, with surface specializations.
