The size and the shape of the cell vary from millimeter to microns, which are usually based on the type of function that it performs. A cell structure is composed of many components which are present inside the cell. In addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others. If the T Cell expresses CD4, it is converted into a T-helper cell (Th) which has a double function: to produce cytokines and to stimulate B Cells to generate Abs.

Cells contain structures and systems in the same way the human body has structures (e.g., bones, muscles, blood vessels) and systems (e.g., circulatory, digestive). The two main types of cells are prokaryotic cells (lacking a nucleus) and eukaryotic cells (containing a well-organized, membrane-bound nucleus). The neuron is the more functionally important of the two, in terms of the communicative function of the nervous system.

BIOLOGY 12 - CELL STRUCTURE & FUNCTION: Chapter Notes THE CELL THEORY • although different living things may be as unlike as a violet and an octopus, they are all built in essentially the same way. Key Takeaways Organelles are structures within a cell that perform specific functions like controlling cell growth and producing energy. Plant and animal cells can contain similar types of organelles. However, certain organelles can only be found in plant cells and certain organelles can only be found in animal cells. Examples of organelles found in eukaryotic cells include: the endoplasmic reticulum (smooth and rough ER), the Golgi complex, lysosomes, mitochondria, peroxisomes, and ribosomes. More items...
