Study Notes
Plant and Animal Cells Key Features
- Cell Membrane: Semi-permeable barrier; maintains cell structure and regulates material movement in and out.
- Nucleus: The cell's control center; houses DNA and regulates cellular activities.
- Cytoplasm: Viscous fluid that fills the cell, where various cellular processes occur.
- Ribosomes: Site of protein synthesis; can be found freely in the cytoplasm or attached to the endoplasmic reticulum.
- Mitochondria: Known as the "powerhouse" of the cell; responsible for aerobic respiration, converting glucose into usable energy.
- Cell Wall: A rigid layer composed of cellulose, providing strength and structure; unique to plant cells.
- Vacuole: Membrane-bound space filled with sugars and minerals; serves as the cell's storage compartment.
- Chloroplast: Contains chlorophyll for photosynthesis; only found in plant cells.
Genetic Material and Energy
- DNA: Molecule that encodes genetic information essential for growth, development, and function.
- Chlorophyll: Pigment in chloroplasts that captures light energy for photosynthesis; critical for plant energy conversion.
Differences Between Plant and Animal Cells
- Plant Cells: Characterized by a square shape, cell wall, chloroplasts, and a large central vacuole.
- Animal Cells: Typically round in shape; contain multiple small vacuoles instead of a large central one.
