Study Notes
Cell Types
- Prokaryotes are simple cells, exemplified by bacteria.
- Eukaryote cells are larger and more complex, containing membrane-bound organelles.
Cell Structure
- Cytoplasm refers to the interior of the cell, excluding the nucleus.
- The cytoskeleton provides structural support to the cell and assists in its movement.
- All cells feature a cell membrane, a flexible barrier that encloses the cell.
Transport Mechanisms
- Diffusion involves the movement of particles from areas of higher concentration to lower concentration.
- In comparing solutions, a hypertonic solution has a higher concentration of solutes, while a hypotonic solution has a lower concentration.
- Endocytosis is the mechanism by which cells take in materials through the invagination of the cell membrane.
- Phagocytosis is a type of endocytosis used by amoebas to ingest food and other materials.
Cellular Functions
- Cell specialization allows for the differentiation of cells to perform distinct tasks efficiently.
- Facilitated diffusion utilizes protein channels to assist glucose in crossing the cell membrane.
- Osmosis is the specific diffusion of water across a selectively permeable membrane.
- Active transport is the energy-requiring process that moves materials across a membrane against their concentration gradient.
