Study Notes
Organelles in Animal Cells
Vacuole
- A membrane-bound organelle that stores water, salts, and other substances
- Helps maintain cell turgor pressure and osmoregulation
- Can also store waste products and recycling cellular debris
- Typically larger in plant cells, but smaller in animal cells
Centrioles
- Small, cylindrical organelles near the nucleus
- Composed of microtubules and play a key role in cell division
- Help form the spindle fibers during mitosis
- Also involved in the formation of cilia and flagella
Microtubules
- Part of the cytoskeleton, providing structural support and shape to the cell
- Composed of tubulin proteins and are dynamic, constantly assembling and disassembling
- Involved in cell division, intracellular transport, and maintenance of cell shape
- Can also be involved in the movement of organelles and chromosomes
Golgi Apparatus
- A complex of flattened sacs and tubules that process and modify proteins and lipids
- Receives proteins and lipids from the rough ER and modifies them for transport
- Packages proteins and lipids into vesicles for secretion or transport to other parts of the cell
- Plays a key role in cell signaling and protein synthesis
Endoplasmic Reticulum (ER)
- A network of membranous tubules and cisternae that is involved in protein synthesis and transport
- Two types: rough ER (with ribosomes) and smooth ER (without ribosomes)
- Rough ER is involved in protein synthesis and transport, while smooth ER is involved in lipid synthesis and detoxification
- Plays a key role in the synthesis and transport of proteins and lipids in the cell

Endoplasmic Reticulum (ER)
- A network of membranous tubules and cisternae involved in protein synthesis and transport
- Consists of rough ER (with ribosomes) and smooth ER (without ribosomes)
- Rough ER synthesizes and transports proteins, while smooth ER synthesizes lipids and detoxifies
- Plays a key role in synthesizing and transporting proteins and lipids in the cell
