Study Notes
Diffusion & Osmosis
- Diffusion and osmosis are similar in that both involve transport of substances.
- Both are based on the principle of substances moving from an area of high to low concentration.
- Diffusion moves substances from high to low concentration throughout the cell, while osmosis is the movement of water across a membrane from high to low concentration.
- Diffusion does not require energy but osmosis requires energy.
Cell Cycle
-
Mitosis:
- Prophase: Cell prepares for division
- Metaphase: Chromosomes line up in the middle of the cell
- Anaphase: Sister chromatids separate
- Telophase: Cell finishes dividing
- Cytokinesis: Cell splits
- Interphase: Cell grows, copies DNA
Tumors
- Benign tumors are non-cancerous and do not spread.
- Malignant tumors are cancerous and spread rapidly.
Mitochondria
- The mitochondria is involved in cellular respiration.
- They are the powerhouse of the cell
Tissues
- Epithelial Tissue: Covers body surfaces, lines organs, and forms glands.
- Connective Tissue: Supports, connects, and insulates.
- Muscle Tissue: Enables movement.
- Nervous Tissue: Enables communication and sensation through electrical signals.
Plant Tissue
- Dermal tissue: covers the outside of the plant
- Vascular tissue: transports water and nutrients
- Ground tissue: makes up all plant tissues aside from vascular and dermal
Plant Systems
- Function of a plant root: absorption of water and minerals and food storage.
