The nucleus is a large organelle that contains the cell's genetic information. Most cells have only one nucleus, but some have more than one, and others—like mature red blood cells—don't have one at all. Within the nucleus is a spherical body known as the nucleolus, which contains clusters of protein, DNA, and RNA.

1. Plasma membrane: a selective barrier which encloses a cell (plant and bacteria cells also contain a cell wall ). 2. Cytosol: located inside the plasma membrane, this is a jelly-like fluid that supports organelles and other cellular components. 3. Cytoplasm: the cytosol and all the organelles other than the nucleus. 4.

Cells are the fundamental unit of life. All living things are composed of cells. While there are several characteristics that are common to all cells, such as the presence of a cell membrane, cytoplasm, DNA and ribosomes, not all cells are the same. Prokaryotic cells lack a nucleus and membrane-bound organelles.
Cell Structure
A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.

What is a cell? Facts
cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature. These cells cooperate with other specialized cells and become.

Cell Membrane: The cell membrane or plasma membrane is a selectively permeable lipid bilayer that encloses the contents of the cell and regulates the transport of materials into and out of it. Cytoplasm: The cytoplasm is the jelly-like fluid that gives a cell is shape and contains the molecules the cell needs for its processes.

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles. Cell membrane Every cell in the body is enclosed by a cell ( Plasma) membrane.

The plasma (cell) membrane separates the inner environment of a cell from the extracellular fluid. It is composed of a fluid phospholipid bilayer (two layers of phospholipids) as shown in figure 4.1.2 4.1. 2 below, and other molecules. Not many substances can cross the phospholipid bilayer, so it serves to separate the inside of the cell from.

Figure 6.4 Animal cell mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence. Mitosis is usually accompanied by cytokinesis, shown here by a transmission electron microscope.
