Internal Leaf Parts & Function
Lower epidermis - outmost tissue on the lower side of the leaf; protects the leaf
Upper epidermis - outmost tissue on the upper side of the leaf; protects the leaf
Palisade layer - rows of elongated cells in the upper center of leaf; site of photosynthesis
Cuticle - waxy layer on the covering the epidermis; holds in moisture, prevents too much absorption of water
Stoma - opening between the guard cells; allows for gas exchange and some water
Guard cells - surround the stoma; control the opening and closing of the stoma
Vein - supply support for the leaf; contain the xylem and the phloem
Spongy layer - irregular shaped cells in lower center of leaf; absorbs gas & some water
Air space - space in the spongy layer; contain gases
Xylem - found in the vein; transports minerals and water from roots to shoots
Phloem - found in the vein; transports sugar & other products of photosynthesis from leaves to other parts of the plant
Chloroplast - cells in the leaves that contain chlorophyll; trap light energy and convert it to chemical energy
Mesophyll - all of the middle tissue of the leaf
What else can I help you with?
What is the function of the external leaf structure?
The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
What are the lobes on a leaf and how do they contribute to the overall structure and function of the leaf?
The lobes on a leaf are the separate sections or divisions that extend out from the main part of the leaf. They contribute to the overall structure and function of the leaf by increasing the surface area for photosynthesis, allowing for more efficient absorption of sunlight and exchange of gases. This helps the leaf to produce food and oxygen for the plant.
What is the function of a stipule in relation to a leaf structure?
A stipule is a small, leaf-like structure found at the base of a leaf stalk. Its main function is to protect the leaf bud as it grows and to help regulate the flow of nutrients to the leaf.
Would a leaf function as an organ organ system or tissue to make food for a plant?
A leaf functions as a tissue in a plant, specifically as part of the plant's organ system for photosynthesis. The leaf contains chlorophyll, which absorbs sunlight and utilizes it to convert carbon dioxide and water into glucose, the plant's food source.
Stalk that joins the leaf blade to the stem?
The stalk that joins the leaf blade to the stem is called the petiole. Its primary function is to support the leaf and connect it to the rest of the plant's vascular system for the transport of nutrients and water.

What is the function of capillaries in the leaf?
function of capillaries in leaf
What is the function of the external leaf structure?
The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
What is the parts of the outer part of the leafs?
The outer part of the leaf is called the cuticle. It is a waxy layer and does not comprise of live cells. It's function is to prevent the leaf from desiccation (drying out).
What are the lobes on a leaf and how do they contribute to the overall structure and function of the leaf?
The lobes on a leaf are the separate sections or divisions that extend out from the main part of the leaf. They contribute to the overall structure and function of the leaf by increasing the surface area for photosynthesis, allowing for more efficient absorption of sunlight and exchange of gases. This helps the leaf to produce food and oxygen for the plant.
What are the function of the vain?
The function of the veins in a leaf is to transport food to different parts of the leaf
What is the function of the leaf blade?
The function of the leaf blade is to abosorb light and make food.
Why is the leaf called the jack-of-all-trades organ of the pant?
Leaf called the jack of all trades because it can perform all the function in plants. Leaf produces food,stores it, and transport it to the other part of the plant.
Give the function of each part?
mouth,esophagus,and stomach
How can you tell the difference between a leaf and a leaflet?
Leaf is part of a plant. Leaflet is part of a compound leaf.
What is the function of a stipule in relation to a leaf structure?
A stipule is a small, leaf-like structure found at the base of a leaf stalk. Its main function is to protect the leaf bud as it grows and to help regulate the flow of nutrients to the leaf.
