What is the inside of a leaf called?
Most of the interior of the leaf between the upper and lower layers of epidermis is a parenchyma (ground tissue) or chlorenchyma tissue called the mesophyll (Greek for “middle leaf”). This assimilation tissue is the primary location of photosynthesis in the plant.
What is stored in a leaf?
Starch is stored in the stroma of the chloroplasts and in the cytoplasm of leaves.
What is leaf made of?
A leaf is made of multiple layers that are sandwiched between two layers of tough skin cells called the epidermis. The epidermis also secretes a waxy substance called the cuticle. These layers protect the leaf from insects, bacteria, and other pests.
Is a leaf a tissue or an organ?
A leaf is an organ. Leaves are the main photosynthetic organs of plants and are filled with palisade cells that have the chloroplasts needed for…
What are the parts of a leaf and their functions?
Structure-Function Relationship: Leaves
| Name of Structure | Structure | Function |
|---|---|---|
| Pith | Parenchyma with vacuoles and plastids | Storage, support |
| Plasmodesmata | Openings between sieve tubes connecting cytoplasm | Transport of sap |
| Spongy cells | Rounded, widely spaced, near stomata | Allow gas exchange |
| Suberin | Waxy molecule | Waterproofing |
What are the 4 parts of a leaf?
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
What is structure of leaf?
All leaves have the same basic structure – a midrib, an edge, veins and a petiole. The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive. Plants provide food for all life on the planet.
How does a leaf take in water?
During transpiration, water evaporates from tiny holes in the surfaces of leaves into the air. These tiny holes are called stomata. As water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.
What is the green tissue in the interior of a leaf?
Chloroplasts are concentrated in the cells of the mesophyll, the green tissue in the interior of the leaf. Carbon dioxide enters the leaf and oxygen exists, by way of tiny pores called STOMATA.

Do leaves drink water?
A. While plants can absorb water through their leaves, it is not a very efficient way for plants to take up water. If water condenses on the leaf during high humidity, such as fog, then plants can take in some of that surface water. The bulk of water uptake by most plants is via the roots.
