Study Notes
Cell Theory Postulates
- All living organisms are composed of cells.
- Cells are the basic units of structure and function in living organisms.
- Cells arise from pre-existing cells.
Prokaryotic vs. Eukaryotic Cells
- Prokaryotic cells lack a nucleus and membrane-bound organelles.
- Eukaryotic cells have a nucleus and membrane-bound organelles.
Animal vs. Plant Cells
- Plant cells have cell walls, chloroplasts, and a large central vacuole.
- Animal cells lack cell walls, chloroplasts, and a large central vacuole.
Cell Organelles and Functions (table)
| Organelle | Function | Animal Cell? | Plant Cell? |
|---|---|---|---|
| Cell Wall | Provides structural support | No | Yes |
| Cell Membrane | Regulates what enters and leaves the cell | Yes | Yes |
| Mitochondria | Site of cellular respiration | Yes | Yes |
| Ribosomes | Site of protein synthesis | Yes | Yes |
| Chloroplast | Site of photosynthesis | No | Yes |
| Nucleus | Contains DNA | Yes | Yes |
| Nucleolus | Found within the nucleus; involved in ribosome production | Yes | Yes |
| Centrioles | Involved in cell division | Yes | No |
| Endoplasmic Reticulum | Involved in protein and lipid synthesis | Yes | Yes |
| Golgi Bodies | Processes and packages proteins and lipids | Yes | Yes |
| Vacuole | Stores water and other substances | Yes | Yes (large central vacuole in plants) |
| Lysosome | Contains enzymes that break down waste | Yes | Yes |
Reasons for Cell Division
- Growth
- Repair
- Reproduction
Stages of the Cell Cycle
- Stages and description depend on the specific context of the prompt (mitosis, cytokinesis). Note diagrams are also provided for visual aid
Cytokinesis Differences
- Animal cells: Cytoplasm divides by a cleavage furrow.
- Plant cells: Cytoplasm divides by a cell plate.
Hierarchy of Life
- Cells → Tissues → Organs → Organ Systems → Organisms
Animal Tissues
- Epithelial tissue: Covers and lines body surfaces.
- Connective tissue: Supports and connects body parts.
- Muscle tissue: Enables movement.
- Nervous tissue: Transmits nerve impulses.
Digestive System Organs and Functions (table)
| Organ | Description of Function |
|---|---|
| Mouth | Mechanical digestion, beginning of chemical digestion |
| Salivary Glands | Produce saliva, containing enzymes |
| Esophagus | Transports food from mouth to stomach |
| Stomach | Mechanical and chemical digestion of food |
| Small Intestine | Absorption of nutrients |
| Large Intestine | Absorption of water, elimination of waste |
| Rectum and Anus | Elimination of feces |

| Gall Bladder | Stores bile |
| Pancreas | Produces enzymes for digestion, hormones for regulating blood sugar |
Blood Vessels
| Blood Vessel Type | Structure | Function |
|---|---|---|
| Arteries | Thick, elastic walls | Carry oxygenated blood away from the heart |
| Veins | Thin walls, valves | Carry deoxygenated blood back to the heart |
| Capillaries | Thin walls, single layer of cells | Exchange of substances between blood and tissues |
Blood Cell Types
| Blood Cell Type | Structure | Function |
|---|---|---|
| Red Blood Cells | Biconcave discs, no nucleus | Carry oxygen |
| White Blood Cells | Various shapes, nuclei | Fight infection |
| Platelets | Cell fragments | Involved in blood clotting |
Respiratory System Parts and Functions (table)
| Organ/Structure | Description of Function |
|---|---|
| Nose/Mouth | Intake of air |
| Pharynx | Passageway for air and food |
| Larynx | Voice box; contains vocal cords |
| Trachea | Windpipe, passageway for air |
| Bronchi | Branch into smaller tubes |
| Bronchioles | Smaller tubes leading to alveoli |
| Alveoli | Tiny air sacs where gas exchange occurs |
| Diaphragm | Muscle that aids in breathing |
Musculoskeletal System Role
- Provides support, protection, and movement.
Muscle Tissue Types & Functions
| Muscle Tissue Type | Description of Function |
|---|---|
| Skeletal Muscle | Voluntary movement |
| Cardiac Muscle | Involuntary heart contractions |
| Smooth Muscle | Involuntary movement of internal organs |
Connective Tissues and Functions
| Connective Tissue Type | Description of Function |
|---|---|
| Bone | Support and protection |
| Cartilage | Cushioning and support |
| Tendons | Connect muscles to bones |
| Ligaments | Connect bones to bones |
Nervous System Functions and Divisions
- Functions: Control bodily functions, sensory input, communication throughout the body.
- Two divisions: Central Nervous System (brain and spinal cord); Peripheral Nervous System (nerves branching out).
Cancer Terminology (general)
-
Benign tumor: Non-cancerous growth
-
Malignant tumor: Cancerous growth
-
Metastasis: Spread of cancer cells
