Study Notes
Animal Classification
- Cats are vertebrates, possessing a backbone. Vertebrates have backbones; invertebrates do not.
Biological Organization
- Unicellular Organisms: Organisms composed of a single cell.
- Multicellular Organisms: Organisms composed of more than one cell.
- Cellular Differentiation: The process where cells specialize for specific functions.
- Specialized Cells: Cells with specific tasks.
Levels of Organization (Increasing Complexity)
- Cells
- Tissues
- Organs
- Organ Systems
- Organisms
Animal Tissues
- Connective Tissue: Supports and binds other tissues (e.g., bone, blood, lymph).
- Epithelial Tissue: Forms coverings (e.g., skin, inner linings).
- Muscle Tissue: Enables movement.
- Nervous Tissue: Transmits signals to the brain.
Differentiated Cells
- A differentiated cell is a specialized cell with a specific function (e.g., a blood cell carrying oxygen).
Human Organ Systems
- Circulatory
- Digestive
- Musculoskeletal
- Respiratory
- Nervous
Gas Exchange (Humans vs. Frogs)
- Humans: Inhale air, which travels through the trachea, bronchi, and bronchioles to alveoli where gas exchange (oxygen uptake and carbon dioxide release) occurs.
- Frogs: Under water, frogs' skin can absorb oxygen. They can also breathe through the mouth.
Plant Transport
- Plants transport water and minerals from roots to leaves via the xylem. Factors include root pressure, capillary action, and transpiration pull (water evaporation through stomata).
Photosynthesis
- Some organisms performing photosynthesis include algae, trees, flowers, and other plants.
Paramecium Cilia
- Paramecia use cilia (hair-like structures) to move through water and ingest food.
Unicellular Phagocytosis
- Unicellular organisms use phagocytosis (engulfing food particles) to obtain nutrients. This forms a food vacuole where enzymes break down the food.
Organ Systems Table
- (Note: The provided table is incomplete and may need further details for a full study aid.)*
| Organ System | Function | Example Organs |
|---|---|---|
| Circulatory | Transports oxygen to the body | Heart, blood vessels |
| Respiratory | Supplies oxygen for breathing | Nose, trachea |
| Digestive | Breaks down food consumed | Mouth, stomach |
| Musculoskeletal | Provides body support | Bones |
| Nervous | Sends signals to the brain | Brain |
Environmental Responses
- Vertebrates: Respond to the environment using the nervous and musculoskeletal systems (e.g., pain response, movement).
- Trees: Responding to cold/dry weather by shedding leaves to reduce water loss.
Major Organism Groups
- Fungi
- Bacteria
- Animals
- Plants
- Protists
