plant tissue

• Where does photosynthesis take place in plants?

  In leaves
• What is the leaf classified as in plant anatomy?

  A plant organ
• What are the two types of epidermal cells in a leaf?

  Upper epidermis and lower epidermis
• What is the primary function of the epidermis in a leaf?

  To protect the surface of the leaf
• Why is the upper epidermis transparent?

  To allow light to pass through
• What is the function of the waxy cuticle on the leaf?

  To reduce water evaporation
• What are stomata?

  Tiny pores on the lower epidermis
• What do stomata allow to enter and leave the leaf?

  Carbon dioxide enters, oxygen leaves
• What are guard cells?

  Cells that surround stomata
• What is the role of palisade mesophyll in a leaf?

  Contains chloroplasts for photosynthesis
• What do chloroplasts contain that is essential for photosynthesis?

  Chlorophyll
• What is a key feature of spongy mesophyll?

  It is full of air spaces
• How does carbon dioxide move in the leaf?

  From stomata through spongy mesophyll
• What is the function of xylem tissue?

  Transports water from roots to leaves
• What mineral is transported by xylem and is used to make chlorophyll?

  Magnesium
• What does phloem tissue transport?

  Dissolved sugars produced by photosynthesis
• What is the process of moving sugars through phloem called?

  Translocation
• Where is meristem tissue found in plants?

  At growing tips of shoots and roots
• What type of cells does meristem tissue contain?

  Stem cells
• What can stem cells in meristem tissue differentiate into?

  Different types of plant tissue
• What are the main tissues found in a leaf and their roles?

  • Epidermal tissue: Protects leaf surface
  • Palisade mesophyll: Contains chloroplasts for photosynthesis
  • Spongy mesophyll: Allows gas diffusion
  • Xylem: Transports water and minerals
  • Phloem: Transports sugars
  • Meristem: Contains stem cells for growth
• finish sentence

  sugars are transported to storage organs through the stomata
• how does closing its stomata help a plant

  reduces water loss
