Cytokinesis – division of plasma membrane; two daughter cells result with exact genetic information (in plant cells a “cell plate” forms along the center of the cell and cuts the cell in half; cell plate forms new cell walls once the plasma membrane divides) RESULTS: Two daughter cells (body cells)

Challenges the idea that a cell has one nucleus. Muscle cells have more than one nucleus per cell Muscle Cells called fibers can be very long (300mm). They are surrounded by a single plasma membrane but they are multi-nucleated (many nuclei).This does not conform to the standard view of a small single nuclei within a cell
Plasma Membrane (Cell Membrane)
The thin plasma membrane surrounds the cell, separating its contents from the surroundings and controlling what enters and leaves the cell. The plasma membrane is composed of two main molecules, fats (in fact phospholipids) and proteins.

1. If a tiny hole is made in a plasma membrane, it usually "heals" immediately, and no harm results. What property of the plasma membrane allows this? 2. Lipids, small molecules, and uncharged particles pass into and out of the cell with relative ease. What characteristics of the cell membrane can be inferred from these observation? 3.

The plasma membrane is a lipid bilayer with imbedded and peripheral proteins; it regulates the movement of substances into and out of the cell. b. The plasma membrane can form internal pouches called mesosomes, which increase the internal surface area of the membrane for enzyme attachment. c.

Lesson 1: Movement across Cell Membranes. Many substances move into and out of cells through their plasma membranes. Some of these substances move passively – that is, the cell does not have to use energy to make them move. Passive processes include diffusion, facilitated diffusion and osmosis.

Nuclear membrane. Plasma cell membrane. Ribosomes. The cell is the basic unit of function and reproduction because. subcellular components cannot regenerate whole cells. cells are totipotent. single cells can sometimes produce an entire organism. cells can only come from preexisting cells. a cell can arise by the fusion of two cells.
