    • What type of gas exchange occurs in the spongy mesophyll of a leaf?
      CO2 and O2
    • What do vascular bundles transport throughout the plant?
      Water, nutrients, and photosynthates
    • Chloroplasts are abundant in the spongy mesophyll of a leaf.
      False
    • Gas exchange in leaves occurs through the stomata
    • Transpiration is regulated by guard cells, which control the opening and closing of stomata
    • The lamina of a leaf is designed to capture sunlight for photosynthesis
    • The lamina's large surface area maximizes light absorption
    • What does the spongy mesophyll allow in a leaf?
      Gas exchange
    • Stomata are small pores on the leaf surface that regulate gas exchange and water loss.
      True
    • The opening and closing of stomata balances gas exchange and water conservation.
      True
    • The spongy mesophyll contains chloroplasts for photosynthesis.
      False
    • Stomata regulate gas exchange and water loss
    • Order the main parts of the external anatomy of a leaf.
      1️⃣ Lamina
      2️⃣ Petiole
      3️⃣ Veins
    • Match the leaf part with its function:
      Lamina ↔️ Captures sunlight
      Petiole ↔️ Supports leaf, connects to stem
      Veins ↔️ Transports water and nutrients
    • The spongy mesophyll allows for gas exchange and photosynthesis.
      True
    • Xylem transports water and minerals using dead cells with thick walls
    • Trichomes are hair-like outgrowths on the leaf surface that can reduce water loss and deter herbivores.
      True
    • What process is the leaf structure adapted to maximize?
      Photosynthesis
    • Stomata regulate both gas exchange and water loss in leaves.

      True
    • The petiole connects the leaf to the stem
    • What controls the opening and closing of stomata?
      Guard cells
    • What is the function of the lamina in the external anatomy of a leaf?
      Captures sunlight
    • Match the leaf part with its primary function:
      Palisade Mesophyll ↔️ Photosynthesis
      Spongy Mesophyll ↔️ Gas exchange
      Stomata ↔️ Transpiration
      Vascular Bundles ↔️ Transport of water
    • The petiole connects the leaf to the stem and supports the lamina.

      True
    • What is the function of the epidermis in a leaf?
      Protective outer layer
    • Vascular bundles transport the products of photosynthesis throughout the leaf
    • Stomata allow the uptake of carbon dioxide and the release of oxygen
    • Match the leaf part with its function in photosynthesis:
      Epidermis ↔️ Protective outer layer
      Palisade Mesophyll ↔️ Photosynthesis
      Spongy Mesophyll ↔️ Gas exchange
      Stomata ↔️ Water loss regulation
    • What is the function of the epidermis in a leaf?
      Provides a protective outer layer
    • The leaf structure includes large surface area, thin layers, and abundant chloroplasts to maximize photosynthesis.

      True
    • The lamina is the broad, flat surface of the leaf designed to capture sunlight
    • What are the key components of the epidermis in the internal anatomy of a leaf?
      Cuticle, guard cells
    • What does the vascular bundle in a leaf transport?
      Water and nutrients
    • What does phloem transport in leaves?
      Sugars and organic compounds
    • What is the function of hydathodes in leaves?
      Excretion of excess water
    • The palisade mesophyll contains chloroplasts for photosynthesis
    • Match the leaf part with its function in photosynthesis:
      Palisade Mesophyll ↔️ Photosynthesis
      Stomata ↔️ Gas exchange and water loss regulation
      Vascular Bundles ↔️ Transport water, nutrients, and photosynthates
    • What is the primary function of the lamina in a leaf?
      Captures sunlight
