What is the structure of leaf?
Leafs are flat parts of plants, which grow from stem, twig, branch, etc. They make food for the plant through a process named photosynthesis, by taking CO2 and releasing O2 to the atmosphere. You can study its structure by two ways, seeing its external parts and its internal structure (also its cells). Externally: apex (or leaf point), upper epidermis) which protect the cells), margin (the outer edge), veins (they carry water, minerals and food to the plan), lower epidermis (covered by small holes known as stomata), midrib and the petiole (or stem). Internally: cutin (a waxy surface), upper epidermis, palisade cell, chloroplast (contains chlorophyll for the photosynthesis), air space, spongy mesophyll cell (were the respiration takes place), lower epidermis, stoma (opens to allow gases in and out)
Is A Leaf Function As A tissue To Make Food For A Plant?
Yes, a leaf functions as a tissue called a mesophyll to make food for the plant through photosynthesis. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose (sugar), which is used as energy for the plant.
What does leaf cells do?
Leaf cells perform photosynthesis, converting sunlight, water, and carbon dioxide into glucose and oxygen. They also regulate water and gas exchange through stomata, help support the structure of the leaf, and store nutrients for the plant.
Why the cuticle transparent?
The cuticle is transparent because it is made up of a thin, protective layer of cells that lack pigmentation or other substances that would make it opaque. This transparency allows light to pass through and reach the underlying tissue for processes like photosynthesis in plants.
How is the structure of a leaf related to the function?
The most important function of a leaf is photosynthesis: the production of energy from sunlight, carbon dioxide and water. The shape of the leaf helps to maximize the sunlight receiving area and the veins in the leaf make it easier to move the raw materials and products of photosynthesis in and out of the leaf.
What make a leaf waterproof?
The upper skin of the leaf has a layer of wax on it, called a cuticle. This makes the leaf waterproof. The upper skin of the leaf has a layer of wax on it, called a cuticle. This makes the leaf waterproof.
What kind of cells make the cuticle for the leaf?
The cuticle of a leaf is primarily made up of cells called epidermal cells. These cells are located on the outer layer of the leaf and secrete a waxy substance that forms the protective cuticle layer.
What is water in a leaf used for?
Water in a leaf is used for photosynthesis, which is the process by which plants make their own food. Water is essential for transporting nutrients and minerals from the soil to the leaves, and it also helps to maintain the turgidity of plant cells, allowing the leaf to remain rigid and upright for efficient light absorption.
What are grass characteristics?
=have several main roots of the same size..=leaves make a big part of grass plants,,=most grasses have short stems covered by leaf bases..=grasses are efficient in photosynthesis
Main function of a leaf?
Photosynthesis - make food.
How does a leaf make engery?
from the Sun through photosynthesis
What is a main function of a leaf?
to capture photosynthesis and make food
What is is the main function of a leaf?
to capture photosynthesis and make food
What does a leaf need to make photosynthesis?
Photosynthesis in general needs: Carbon dioxide, Water, and energy to be processed. Within the leaf, there are cells; within each cell, there are chloroplast; within the chloroplast, photosynthesis is made.
Why is a leaf part of a plant?
because that's the part that can make photosynthesis
What do leaf make food out of?
They use photosynthesis which means they get their food from the sun.
The leaf main job then is to make?
The cells of a leaf contain large numbers of chloroplasts, the part of the plant responsible for photosynthesis. The main job of a leaf is to collect sunlight which allows the plant to produce carbohydrates via photosynthesis.
