I. B - Cell

Cards (13)

  • Cell wall - outer layer external to the plasma membrane
  • Primary cell wall - cellulose
    Secondary cell wall - lignin
  • Middle lamella - Glues adjacent cell walls together
  • Lacuna - space when the plant is dying
  • Plasmodesmata - connects cytoplasm from one cell to another
  • Protoplast - cell sap of a plant cell, consisting of:
    1. Cell wall
    2. Cell sap
    3. Cytoplasm
  • Plastids - close-related organelles that are unique to photosynthetic eukaryotes
    1. Chloroplasts - site of photosynthesis
    2. Chromoplasts - provide protection
    3. Leucoplasts - food/starch storage
  • Pigments of plastids
    1. Chloroplasts - chlorophyll and carotene
    2. Chromoplasts - carotene and xanthophyll
    3. Leucoplasts - no pigment
  • Types of leucoplasts
    1. Proteinoplast
    2. Amyloplast
    3. Elaioplast
  • Locomotory organelles
    1. Cilia - short, hair-like protrusions
    2. Flagella - long, whip-like
  • Chloroplasts undergo cyclosis to:
    1. Maximize light absorption
    2. Distribute photosynthetic products evenly
  • Plant crystals - store metabolic waste in the central vacuole
  • Compositions of plant crystals and structures
    1. Calcium oxalate
    2. Raphides - needle-like in large numbers
    3. Styloid - large solitary needle
    4. Druse - spherical
    5. Prismatic - prism
    6. Calcium carbonate
    7. Club-like
    8. Worm-like
