    • 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

    • 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
