Ribosome , containing both rRNA and proteins, can be free floating or attached to endoplasmic reticulum. Can either be rough ER with ribosomes attached or smooth ER without. Golgi apparatus , associated with ER in the cytoplasm, for packaging and export of materials. A stack of membranes that can package and secrete, among other things, glycoproteins for the plasma membrane and lysosomes. Lysosomes , in the cytoplasm, are membrane-surrounded pockets of digestive enzymes.
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.
