Hola folks! This is week four of biology and I have a few new things to share with you. I have decided to focus on parts of the Eukaryotic Cell. We did go over parts of the skeleton on Monday, but I'll save that for next week. Lets get to it. I'll simply give you the definitions and what they do.

Cytoskeleton: Structurally supports, gives shape to cell; moves cell and its parts

Mitochondrion: Energy powerhouse produces ATP by cellular respiration

Centrioles: Social centers that produce and organize microtubules. This organelle has no cell membrane.

Plasma membrane: Controls the kinds and amounts of substances moving into and out of the cell.

Nucleus: Protecting, controlling access to DNA

Ribosomes: This organelle has no cell membrane. Attached to rough ER and free in cytoplasm Sites of protein synthesis.

Rough E.R. (edoplasmic reticulum): Modifies new polypeptides chains

Smooth E.R.: Makes lipids, degrades fats, inactivates toxins

Golgi body: Modifies, sorts, ships proteins and lipids, for exports or for insertion into cell membranes

Lysosomes: Digests, recycles materials

 
Of course all this was found in my textbook that I did cite the first week of my blog. Have a great weekend!!
