Cells
What is the basic structure of a Cell?
- Protoplasm
- Nucleus
- Organelle
- Cytoplasm
- Cell Membrane
Colorless, jellylike substance in cells; contains food elements such as protein, fats, carbohydrates, mineral salts, and water.
Protoplasm
Is the dense, active protoplasm found in the center of the cell. It plays an important part in cell reproduction and metabolism.
Nucleus
Small structures or miniature organs with a cell that have thheir own function.
Organelle
Fluid within the nucleus of the cell that contains proteins and DNA; determines our genetic makeup.
Neucleplasm
The blueprint material of genetic information; contains all the information that controls the function of every living cell.
Deoxyribonucleic Acid (DNA)
All the protoplasm of a cell except that which is in the nucleus; the watery fluid containing food material necessary for cell growth, reproduction, and self-repair.
Cytoplasm
Part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell.
Cell Membrane
What is Mitosis?
The usual process of cell reproduction in human tissue that occurs when the cell divides into two identical daughter cells.
A chemical process that takes place in living organisms whereby the cells are nourished and carry out their activities.
Cell Metabolism
Describe the Body’s Metabolism.
The process of changing food into forms the body can use as energy.
What are the two phases of Metabolism and what are their functions?
- Anabolism: Is constructive metabolism, the process of building up larger molecules from smaller ones. During this process, the body stores water, food, and oxygen for when these substances are needed most for cell growth and repair.
- Catabolism: The phase in which complex compounds within the cell are broken down into smaller ones. This process releases energy that is stored by special molecules to be used in muscle contractions, body secretions, or heat production.
A collection of similar cells that perform a particular function.
Tissue
