Study Notes
Cellular Anatomy
- Organelles are the individual organs of a cell
- Nucleus is the control center for reproduction (containing DNA, hereditary material). It is enclosed by a membrane.
- Nuclear Envelope is the membrane surrounding the nucleus (with pores).
- Nucleolus is inside the nucleus and manufactures ribosomes.
- Ribosomes produce proteins and are located in the cytoplasm or endoplasmic reticulum.
- Cytoplasm is everything between the nucleus and the cell membrane.
-
Endoplasmic Reticulum connects the nucleus to the cell membrane and is used for transport.
- Rough ER processes proteins.
- Smooth ER processes lipids and carbohydrates.
- Mitochondria are the power source of the cell.
- Chloroplasts are found in plant cells and are where photosynthesis occurs.
- Golgi Apparatus packages and secretes cellular products.
- Lysosomes are enzyme-coated organelles used for digestion.
- Chromatin are strands of genetic material which form chromosomes prior to cell reproduction.
- Vacuole primary function is for storage (often a large central vacuole in plants, used to store water and other materials).
- Cell Membrane regulates what enters and exits a cell.
- Cell Wall provides structure and support for plant cells (animal cells do not have cell walls).
Additional Cellular Structures
- Centrioles (T-shaped or barrel-shaped) are used to pull chromosomes apart during cell division.
- Plants do not have centrioles, but have similar structures called centrosomes.
- Fungi and bacteria have cell walls, but their designs differ.
