- Nucleus
- The nucleus directs all activities of the cell including reproduction.
- Nucleolus
- The nucleolus produces ribosomes.
- Mitochondria
- Most of the cell's energy is produced within these rod-shaped organelles.
- Vacuole
- Most mature plant cells have one large vacuole. The sac within the cytoplasm stores water, food, waste products, and other materials./ Some animal cells have vacuoles that store food, water, waste, and other materials.
- Cytoplasm
- The cytoplasm includes a gel-like fluid in which many different organelles are found.
- Cytoskeleton
- The cytoskeleton helps to maintain the cell's shape.
- Golgi Complex
- The golgi bodies recieve materials from the endoplasmic reticulum and send them to other parts pf the cell. They also release materials outside the cell.
- Rough Endoplasmic Reticulum/Smooth Endoplasmic Reticulum
- This network of passageways carries materials form one part of the cell to another.
- Chloroplast
- These organelles capture energy from the sunlight and use it to produce food for the cell.
- Cell Wall
- In a plant cell, a stiff wall surrounds the membrane, giving the cell a rigid, boxlike shape.
- Cell Membrane
- Since an animal cell does not have a cell wall, the cell membrane forms a barrier between the cytoplasm and the environment outside the cell.
- Chromatin
- Contains DNA.
- Lysosome
- These small organelles contain chemicals that break down food particles and worn out cell parts.
- Ribosomes
- These small strcutures function as factories to produce proteins. Ribosomes may be attached to the endoplasmic reticulum, or they may be floating the cytoplasm.
