Plants

• What does the xylem do?


  It conducts water and dissolved minerals from the roots to the leaves.
• What does the phloem do?

  Transports amino acids and sugars throughout the plant.
• How are xylem and phloem organized?

  Vascular bundles
• Does the movement in xylem go in more than one direction?

  No, only one.
• What do pits in plants do?

  Facilitate water movement
• What is root pressure?

  Force that pushes water up from the roots to the stems and leaves.
• What is guttation?


  Where water is forced out of the leave through the stomata.
• What is adhesion?


  When water molecules stick to the walls of their vessel.
• What happens when the vessel is narrow?


  The water rises higher.
• What is transpiration?


  Where water escapes through the pore of a plant.
• What are guard cells in plants?


  Guard cells regulate the rate of transpiration by opening and closing the stomata.
• What are stomata?


  Pores on the surface of plant leaves that allow for gas exchange.
• Can guard cells become turgid?


  Yes, they become turgid when they bend.
• What is the role of cell wall pressure in generating turgor in plants?


  It helps the plant maintain structure and keeps the plant from wilting
• What is the role of cell turgor in plants?


  Cell turgor plays a crucial role in maintaining plant structure and function. It occurs when water flows into the plant cell’s vacuole, causing the vacuole to swell and press against the cell wall.

  This pressure not only helps maintain the plant's rigidity but also supports various physiological processes
