   Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 3.4.2.6 − 7 3.4.2. 6 − 7). When a typical stem vascular bundle (which has xylem internal to the phloem) enters the leaf, xylem usually faces upwards, whereas phloem faces downwards. The conducting cells of the xylem (tracheids and vessel elements ...

   Oct 31, 2023 · Figure 30.10.1 30.10. 1: Mesophyll: (a) (top) The central mesophyll is sandwiched between an upper and lower epidermis. The mesophyll has two layers: an upper palisade layer and a lower spongy layer. Stomata on the leaf underside allow gas exchange. A waxy cuticle covers all aerial surfaces of land plants to minimize water loss.

   What is a protective layer of a leaf?

   • a protective layer that allows light to enter the leaf. It is waterproof in order to prevent water loss by evaporation. Epidermis – transparent, physical defence layer that does not contain chloroplasts. It allows light into the leaf. palisade mesophyll Plant tissue containing closely packed cells in the upper layer of a leaf.

   What is the outer layer of a leaf?

   • These cells form the protective outer layer of the leaf, providing a shield against environmental factors and preventing excessive water loss. Mesophyll Layer: Sandwiched between the upper and lower epidermis lies the mesophyll layer.

   How does the internal structure of a leaf promote photosynthesis?

   • The internal structure of the leaf is also adapted to promote efficient photosynthesis. When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata.

   How are leaves adapted?

   • Leaves are adapted in several ways to help them perform their functions. The internal structure of the leaf is also adapted to promote efficient photosynthesis. When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata.

   Why do leaves have a large surface area?

   • Leaves are thin – ensures all cells receive light. Leaves have a large surface area. spongy mesophyll The plant tissue in a leaf which has loosely packed cells and air spaces between them to allow gas exchange. – have very few chloroplasts and a large surface area to increase the diffusion of carbon dioxide and oxygen.

   What is the function of a leaf in a plant?

   • The leaf is a vital plant organ responsible for photosynthesis, transpiration, and gas exchange. It is typically thin and flat to maximize its surface area, which enhances the absorption of light and carbon dioxide while allowing efficient release of oxygen and water vapor. The structure of a typical leaf consists of several key components:
