Study Notes
Plant Cell - Vacuole
- Occupies ~30% of mature cell volume
- Surrounded by a single-layered membrane (tonoplast)
- Main function is storage (salts, enzymes, etc.)
- Maintains turgor pressure against the cell wall
Plant Cell - Plastids
- Young cells have undifferentiated plastids (proplastids) that multiply by division
- Mature cells develop into various types based on contained pigments
- Chloroplasts: Photosynthesis site, contain chlorophyll
- Leucoplast: Colorless, store oils, proteins
- Chromoplasts: Red, orange, or yellow pigments
Plant Cell - Chloroplast
- Oval-shaped, surrounded by a double membrane
- Thylakoids (sac-like structures) arranged in grana
- Stroma (liquid phase) contains proteins, DNA, RNA, oils, ribosomes, and starch grains
- Chlorophyll pigments used in light energy conversion
- Accessory pigments like carotenoids and xanthophylls are also present
- Converts CO2 and H2O into simple sugars by using light energy
Plant Cell - Mitochondria
- Found in all eukaryotic cells
- Responsible for cellular respiration (creating ATP)
- Site of aerobic respiration (oxygen required)
- Converts chemical energy in food to ATP
- Enclosed by a double membrane
- Inner membrane folds (cristae) to increase surface area
- Contains ribosomes similar to prokaryotic ribosomes
- Mitochondrial DNA (circular) codes for some proteins
- Inner compartment (matrix) contains enzymes for food breakdown
- Intermembrane space is located between the inner and outer membranes
