6 Questions
What is the function of the cell membrane in an animal cell?
Regulates the movement of substances in and out of the cell
Which organelle is responsible for breaking down waste materials in an animal cell?
Lysosome
What is the main function of the mitochondria in an animal cell?
Produce energy through cellular respiration
What is the function of the Golgi apparatus in an animal cell?
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for transportation.
What are the differences between a plant cell and an animal cell?
Some key differences include the presence of a cell wall and chloroplasts in plant cells, while animal cells lack these structures. Additionally, plant cells often have a large central vacuole, while animal cells have smaller or multiple vacuoles.
How does the cytoskeleton contribute to the structure and function of an animal cell?
The cytoskeleton provides structural support, maintains cell shape, and is involved in cell movement and intracellular transport by providing tracks for vesicles and organelles to move along.
Study Notes
Cell Membrane Function
- Regulates what enters and leaves the cell
- Controls the movement of materials in and out of the cell
- Acts as a barrier between the cell and its environment
Organelle Functions
- Lysosomes are responsible for breaking down waste materials in an animal cell
- Contain digestive enzymes that break down and recycle cellular waste and foreign substances
Mitochondria Function
- Generate energy for the cell through cellular respiration
- Convert glucose into ATP (adenosine triphosphate) through cellular respiration
- Often referred to as the "powerhouses" of the cell
Golgi Apparatus Function
- Receives proteins and lipids from the endoplasmic reticulum
- Modifies, sorts, and packages proteins and lipids for transport to other parts of the cell
- Plays a key role in protein synthesis and secretion
Plant vs Animal Cells
- Plant cells have a cell wall, chloroplasts, and a large vacuole, whereas animal cells do not
- Animal cells have lysosomes, whereas plant cells do not
- Plant cells are generally larger than animal cells
Cytoskeleton Function
- Provides structural support and shape to the cell
- Plays a key role in cell division, differentiation, and movement
- Composed of microtubules, microfilaments, and intermediate filaments
