LE - Cell Structures
| Term | Definition |
|---|---|
| Cell membrane | present in animal and plant cells; SEMI-PERMEABLE: allows certain materials in and out of the cell, regulates what enters and leaves |
| Chloroplast | present in plant cells; organelle containing chlorophyll that uses light energy to make CO2, nutrients, and water into sugars in order to make energy |
| Cytoplasm | present in animal and plant cells; fluid, jelly like substance that holds the organelles and protects them |
| Endoplasmic reticulum | present in animal and plant cells; carries substances like proteins through the cell. Some endoplasmic reticulums are smooth (they do not have ribosomes attached) while others are rough (they have ribosomes attached) |
| Golgi body/complex/apparatus | present in animal and plant cells; receives materials from the endoplasmic reticulum and distributes them throughout the cell |
| Large Vacuole | present in plant cells; stores food, water, waste, etc for the cell |
| Lysosomes | present in animal cells; contains chemicals to break down certain materials and dead cells |
| Mitochondria | present in animal and plant cells; known as the powerhouse of the cell, it produces the cell's energy in the form of ATP |
| Nuclear Envelope | present in animal and plant cells; surrounds and protects the nucleus, allowing things in and out of the nucleus |
| Nucleolus | present in animal and plant cells; makes ribosomes for the cell |
| Nucleus | present in both animal and plant cells; directs all cell actions and processes, including reproduction; houses the DNA in the cell |
| Ribosomes | present in animal and plant cells; place where proteins are made |
| Small Vacuole | present in animal cells; transports and stores materials, such as waste products |
| Cell Wall | present in plant cells only; protects the cell and gives the cell shape and structure |
