1. How do multicellular organisms differ from unicellular organisms in terms of their cellular organization and functional capabilities?
2. Which part of the leaf acts as a protective skin, shielding internal tissues from damage and water loss?
3. What is a key component of cellular respiration in cells?
Parts of the leaf
Epidermis, palisade, spongy tissue, stomata, xylem, phloem.
Organizational levels
Cell, tissue, organ, system.
Unicellular vs multicellular
Multicellular have specialized cells; unicellular are single-celled.
Photosynthesis equation
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
Cellular respiration equation
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP.
Xylem — function?
Transports water and minerals upward.
