Cell Model
Animal Cell:
1. Nucleus - controls most cell processes and contains hereditary information of deoxyribonucleic acid
2. Cell membrane - thin, flexible barrier around the cell, support and protect cells, semipermeable
3. Cell wall - strong layer around cell membrane, support and protect cells
4. Cytoskeleton - network of protein filaments that helps the cell maintain its shape, also involved in cell movement
5. Ribosomes - small particles in the cell on which proteins are assembled; made of RNA and protein
6. Endoplasmic Reticulum - organelle in which components of the cell membrane are assembled, also modifies proteins and lipids
7. Golgi Apparatus - combines molecules, packages in vesicles, and either stores for later use or sends it out of the cell
8. Lysosomes - small organelles filled with enzymes; breaks down food into particles for cell
9. Vacuole - cell organelle that stores materials such as water, salts, proteins, and carbohydrates
10. Mitochondria - release/use energy from food to make high-energy compounds that the cell can use to power growth, development, and movement (cellular respiration)

Plant Cell:
11. + Chloroplasts - use energy from sunlight to make energy-rich food molecules in a process known as photosynthesis
(important: chloroplasts make glucose, while the mitochondria break down the glucose for energy)

Bacteria Cell:
12. Flagella - tail of the bacteria cell that allows for "swimming" movement
12. Pili - helps bacteria grasp materials
13. Capsule - encloses the bacteria, form of protection
