Study Notes
Eukaryotes and Prokaryotes
- Eukaryotes include animals, plants, fungi, and protists.
- Bacteria and archaea are prokaryotes.
- Examples: dog (animal), tree (plant), mushroom (fungus), algae (protist), strep (bacteria).
Cell Theory
- Three parts of cell theory:
- All new cells come from old cells.
- Cells are the smallest unit of life.
- Every living thing is made of cells.
Microscopes
- To calculate total magnification, multiply the microscope's number by 10.
Cell Structure - Plant Cells
- Plant cell shape is rectangular.
- Unique organelles: chloroplast, cell wall.
- Functions:
- Chloroplast: controls photosynthesis.
- Cell wall: protects and supports.
- Central vacuole: stores water, regulates turgor pressure.
Cell Structure - Animal Cells
- Animal cell shape is circular.
- Unique organelles: lysosomes, centrioles.
- Functions:
- Lysosomes: break down waste.
- Centrioles: control cell division.
Cell Organelles and Functions
- Mitochondria: Converts food into energy.
- Golgi bodies: Packages and delivers proteins.
- Organelles: Located within the cell membrane.
- DNA: Found within the cell nucleus.
- Cell membrane: Controls what enters and leaves the cell.
- Rough ER: Stores proteins.
- Smooth ER: Stores fats.
- Centrosome: Controls animal cell division.
- Chloroplast: Controls plant cell division.
- Nucleus: Makes ribosomes.
- Cytoplasm: Contains cell contents.
- Cytoskeleton: Structures, supports, and transports for the cell.
- Ribosome: Makes proteins.
- Vacuoles: Store water and nutrients.
- Vesicles: Transport nutrients.
- Cell membrane: Separates the cell from its environment.
- Cell wall: Protects the cell.
