  • It is the main photosynthetic organ of most vascular plants.
    Leaves
  • It is the broad flattened structure of the plant containing the green pigment called chlorophyll which helps the plant from photosynthesis.
    Leaf
  • What are the main functions of plant leaves?
    1. Photosynthesis
    2. Gas Exchange
    3. Transpiration
  • It is the process of conversion of carbon dioxide and water to glucose and oxygen in the presence of sunlight.
    Photosynthesis
  • What is the formula of photosynthesis?
    6CO2 + 6H2O - (sunlight) -> C6H12O6 + 6O2
  • It refers to the diffusion of gases from an area of higher concentratio to an area of lower concentration.
    Gas Exchange
  • This is where plants obtain the gases they need.
    Leaves
  • What are the two process of gas exchange?
    1. Photosynthesis
    2. Respiration
  • It is a continuous process that takes place in the plants throughout the day and night.
    Respiration
  • This gas exchange occurs only in the daytime in the presence of sunlight and oxygen.
    Photosynthesis
  • During this gas exchange, carbon dioxide moves in through the stomata while the oxygen moves out.
    Photosynthesis
  • Where do gas exchange takes place?
    Stomata
  • What is the process of gas exchange?
    Diffusion
  • During this gas exchange, oxygen enters the plant through the stomata, and carbon dioxide is released.
    Respiration
  • It is the removal of excess water in the form of water vapor. It occurs by the opening of stomata present in the leaves.
    Transpiration
  • It is the minute pores in the epidermis where gas exchange occurs.
    Stomata
  • It is a waterproof covering made up of cutin, waxes, and polysaccharides. It is generally described as an extracellular thick waxy layer that covers the outside part of the epidermis, and helps plants conserve water.
    Cuticle
  • These are two kidney-shaped cells found on the leaf epidermis and surrounds the stomata. It opens and closes the stomata and controls water loss within a leaf.
    Guard Cells
  • What is the plural term of stoma?
    Stomata
  • It is also called the "middle leaf."
    Mesophyll
  • What are the two layers of Mesophyll?
    1. Palisade
    2. Spongy
  • It is a rectangular layer that creates a layer below the upper epidermis of the plant. It houses most of the leaf's chloroplasts, that is why it serves as the leaf's photosynthesis layer.
    Palisade Layer
  • It is a layer of mesophyll found internally to the lower epidermis, and facilitates the exchange of gases.
    Spongy Layer
  • It is the only layer of mesophyll present in monocots.
    Spongy Layer
  • It is the outer layer of the leaf and it helps protect the leaf by aiding in preventing water loss and providing an extra layer between the outside and inside of the leaf.
    Epidermis
  • It is the flattened surface (broad portion) of a leaf.
    Blade
  • It is the tip of the leaf.
    Apex
  • It is the leaf edge boundary area.
    Margin
  • These are vascular tissue bundles that support the leaf and transport nutrients.
    Veins
  • It is the central main vein arising from secondary veins. It helps the leaf to keep in an upright position.
    Midrib
  • It is the area of the leaf that connects the blade to the petiole.
    Base
  • It is a thin stalk that attaches the leaf to a stem.
    Petiole
  • These are leaf-like structures at the leaf base.
    Stipules
  • What are the two types of leaves?
    1. Simple
    2. Compound
  • This type of leaf contains a single leaf that attaches to the stem. It has a single blade or lamina and is not divided further into smaller leaflets.
    Simple Leaf
  • The leaves of Banana and Hibiscus are...

    Simple
  • This type of leaf is separated into distinct leaflets, each with its own small petiole (but without an axillary bud).
    Compound Leaf
  • In this type of compound leaf, leaflets are present on the common axis called the rachis; leaves are arranged in the opposite manner.
    Pinnately Compound Leaves
  • In this type of compound leaf, leaflets are attached at a single point of the petiole.
    Palmately Compound Leaves
  • What type of leaf do Neem and Rose have?
    Pinnately Compound Leaves
