2: Hello Everyone. My name is Robyn Hornsby. I would like to welcome you to a little preview of "The Animal Composite Cell."
4: The Nucleus It is spherical. It is sometimes known as the control center of the cell. It contains genetic material and a nucleolus. It is also surrounded by a nuclear membrane.
6: The Nuclear Envelope The nuclear envelope is a double lipid bilayer that holds the genetic material of the eukaryotic cells. It also helps with the organization and transcriptional activity of chromatin.
8: The Nucleolus It is a small dense body made of RNA and protein. It has no surrounding membrane. It also produces ribosomes.
10: Chromatin & Chromosomes Chromosomes are organized structures of DNA and proteins. They are visible during cell reproduction. They are also found in the nucleus. Chromatin is a combination of DNA, RNA, and protein. It makes up chromosomes. It is found inside the nuclei of eukaryotic cells.

12: Cell Membrane The cell membrane is semipermeable: it lets something pass through, but not everything. It is made up of lipids (fats) and proteins. It surrounds the protoplasm of a cell. It seperates the intracellular components from the extracellular environment.
14: Cytoplasm A cytoplasm is a jelly-like substance that fills the inside of the cell. It is only 80% of water and almost clear. And it contains organelles like mitochondria.
16: Endoplasmic Reticulum The endoplasmic reticulum is a series of channels and tunnels (transport). It connects the nucleus to the cell membrane. The rough ER has ribosomes on the surface. The smooth ER doesn't contain ribosomes.
18: Ribosomes Ribosomes produce proteins. They are found on the rough endoplasmic reticulum. They are also found floating around in the cytoplasm.
20: Golgi Apparatus The Golgi Apparatus is an organelle. Its important function is the packaging of protein for transportation throughout the cell.
22: Mitochondria The mitochondria is the power house of the cell. It produces energy. There are more in the mucsle cells than the other cells. It produces ATP by oxidizing the products of glucose.
24: Peroxisomes Peroxisomes rid the cell of toxic substances like hydrogen peroxide. They oxidize the cell of alcohol and other poisons. They also aide in the formation of membranes.
26: Microfilaments and Microtubles Microfilaments are solid rods made of protein. They regulate the shape and movement of the cell's surface. They also help develop flagella and cillia. Microtubles are straight, hollow tubes. They are the major component of flagella and cillia. They help form spindle fibers during mitosis.

28: Centrosome Centosomes are important in cell division. They produce microtuble fibers. They also contain the centrioles.
30: Cilia and Flagella They are the movement of the cell. They move particles past the cell. They are extensions of the cell membrane. Villi absorb.It is found in the small intestine.

32: Vesicles A vesicle transports substances throughout the cell.
