Study Notes
Cell Wall
- Present in plants, algae, fungi, and bacteria; absent in animal cells.
- Composed mainly of cellulose in plant cells.
- Provides structural support and maintains cell shape.
Cell Membrane
- Outermost covering in animal cells; located inside the cell wall in plant cells.
- Partially permeable, also known as the plasma membrane.
- Composed of lipids and proteins; regulates entry and exit of substances.
Nucleus
- Central organelle in animal cells, pushed to the side by vacuole in plant cells.
- Functions as the control center of the cell, often described as the brain.
- Bounded by a nuclear membrane; contains nucleoplasm with chromosomes.
- Chromosomes consist of DNA and proteins, essential for genetic information.
Cytoplasm
- Semi-viscous substance filling the cell, consisting mainly of water, salts, and proteins.
- Most cellular functions occur here, supporting the organelles.
Chloroplast
- Found only in plant cells; contains chlorophyll, the green pigment.
- Chlorophyll captures sunlight for photosynthesis, making chloroplasts the food producers of plant cells.
Ribosomes
- Small structures in cytoplasm responsible for protein synthesis from amino acids.
Centrioles
- Paired cylindrical structures located near the nucleus in animal cells.
- Not present in plant cells; assist in cell division by moving to opposite poles of the nucleus.
Endoplasmic Reticulum
- Network of tubular membranes in the cytoplasm, involved in transporting materials within the cell.
