Study Notes
Modern Cell Theory
- All life's energy processes (metabolism and biochemistry) take place within cells.
- The cell is the fundamental structural and functional unit of all living organisms.
- All cells arise from pre-existing cells through cell division.
Kingdoms with Eukaryotic Cells
- Plantae, Animalia, Fungi, and Protista
Kingdoms with Cell Walls
- Four kingdoms: Plantae, Monera (includes Eubacteria and Archaebacteria), Protista, and Fungi.
Domain of Prokaryotes
- Includes Eubacteria and Archaebacteria.
Domain of Eukarya
- Includes Plantae, Animalia, Fungi, and Protista.
Cell Types
- Divided into prokaryotic and eukaryotic cells.
Fungi
- Eukaryotes
- Can be grown on cell-free media.
- Many fungi are decomposers, but some are parasitic.
Organelles
- Mitochondria: Site of ATP production (cellular respiration).
- Smooth ER: Site of steroid hormone synthesis from cholesterol.
- Ribosomes: Site of protein synthesis.
- Lysosomes: Contain hydrolytic enzymes for cellular digestion.
- Golgi Apparatus: Processes and packages proteins for secretion or use within the cell.
Prokaryotic vs. Eukaryotic Cells
- Common features: DNA, ribosomes, cytoplasm, plasma membrane.
- Prokaryotic cells: Small and simple, lack a nucleus and organelles, single-celled, circular chromosome.
- Eukaryotic cells: Large and complex, contain a nucleus and organelles, single or multicellular, linear chromosomes.
Peroxisomes
- Specialized vesicles containing various enzymes.
- Enzymes are produced in the rough endoplasmic reticulum.
Cytoplasm
- All living material inside a cell, except the nucleus.
Phospholipid Head
- Hydrophilic (water-loving).
Protein Synthesis
- Occurs in ribosomes.
Double Membrane-Bound Organelles
- Chloroplasts, Mitochondria
Organelle Function
- Mitochondria: Cellular respiration
- Nucleus: Contains DNA, controls cellular activities.
- Ribosomes: Synthesize proteins.
- Vacuole: Storage of water, nutrients, and waste.
Ribosomes
- Structures of two parts, with a diameter of 20 nm, that are attached to membranes within cells.
