plant

• What is the function of epidermal tissue in plants?

  It covers surfaces and protects the plant
• What role do root hair cells play in plants?

  They absorb water and minerals
• What is the primary function of palisade mesophyll?

  It contains many chloroplasts for photosynthesis
• Why does spongy mesophyll have air spaces?

  To allow gas exchange for photosynthesis and respiration
• What are xylem and phloem classified as?

  Vascular tissues
• What does phloem transport in plants?

  Phloem transports dissolved sugars
• What is the function of xylem in plants?

  Xylem transports water and minerals
• What is transpiration in plants?

  The loss of water vapor from leaves through the stomata
• How does transpiration affect water movement in plants?

  It creates a pull that draws water up from the roots through the xylem
• What is translocation in plants?

  The movement of dissolved sugars from the leaves to other parts of the plant
• What are stomata and their function?

  Stomata are tiny openings on the leaf surface that allow gas exchange
• How do guard cells regulate stomata?

  They control the opening and closing of stomata to regulate water loss and gas exchange
• What are the main types of plant tissues and their functions?

  • Epidermal Tissue: Covers surfaces and protects the plant; includes root hair cells for absorption.
  • Palisade Mesophyll: Contains chloroplasts for photosynthesis.
  • Spongy Mesophyll: Allows gas exchange with air spaces.
  • Xylem: Transports water and minerals.
  • Phloem: Transports dissolved sugars.
• What processes are involved in water and nutrient movement in plants?

  • Transpiration: Loss of water vapor from leaves, creating a pull for water uptake.
  • Translocation: Movement of dissolved sugars from leaves to other parts of the plant.
• How do stomata and guard cells function in plants?

  • Stomata: Tiny openings for gas exchange.
  • Guard Cells: Control the opening and closing of stomata to regulate water loss and gas exchange.
