Study Notes
Levels of Organization
- Hierarchical structure in biology includes organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere.
Structures for Cell Motility
- The cytoskeleton provides structural support and facilitates cell movement.
Chlorophyll Storage
- Chlorophyll is stored in the thylakoid membrane of chloroplasts, crucial for photosynthesis.
Mitochondrial Function
- Mitochondria produce ATP, the energy currency of the cell, through cellular respiration.
Organelle Synthesis
- The endoplasmic reticulum synthesizes new molecules, including proteins and lipids.
Cell Membrane Function
- The cell membrane protects the cell and regulates the transport of substances in and out.
Cell Membrane and Homeostasis
- The cell membrane maintains homeostasis by managing the internal environment and ensuring the balance of substances.
Cellular Transport Processes
- Osmosis describes the diffusion of water molecules across a semipermeable membrane, crucial for maintaining cell turgor.
Egg Reaction in Solutions
- Isotonic solutions have equal solute concentrations; hypertonic solutions cause water to exit the cell, while hypotonic solutions lead to water entering the cell.
Cellular Transport Overview
- Review processes: Osmosis (water movement), Diffusion (solute movement), Facilitated Diffusion (assisted transport), and Active Transport (energy-requiring movement).
