Study Notes
Cells: The Building Blocks of Life
- Cells are the fundamental units of all living organisms.
- Cells are incredibly small, often needing a microscope to be seen.
- Some organisms, like bacteria, are unicellular (composed of a single cell), while others like trees and whales are multicellular (composed of many cells).
- Multicellular organisms often have specialized cells with specific functions.
Animal Cell Structure
- Animal cells typically have an irregular shape.
- Key components include:
- Nucleus: Contains the genetic material (DNA), controlling cell activities.
- Cytoplasm: The fluid filling most of the cell, where chemical reactions occur.
- Cell membrane: The flexible outer layer regulating substance passage in and out of the cell.
- Mitochondria: Tiny structures within the cytoplasm, where energy is released from food (glucose) through respiration.
Plant Cell Structure
- Plant cells usually have a regular shape.
- Plant cells share the same components as animal cells (nucleus, cytoplasm, cell membrane, mitochondria).
- Plant cells possess three additional structures:
- Cell wall: A tough outer layer made of cellulose, providing strength and support.
- Vacuole: A space containing cell sap, maintaining cell firmness.
- Chloroplasts: Structures containing chlorophyll (the green pigment) where photosynthesis takes place – found only in plant cells in green parts.
Cell Types and Activities
- Onion cells: A type of cell available for study.
- Magnification activity: Allows observation of cell detail through various microscope magnifications.
- Atomic labs: A digital activity for learning about cell structure.
