What else can I help you with?
Where are chlorplasts in a leaf?
Chloroplasts are found in the cells of young stems and immature fruits, leaves are the real photosynthetic factories of the plant.
What is the area in a leaf containing many air spaces between cells so that carbon dioxide from the stomata can pass through?
The underside of the leaf.
Is a leaf a cell?
No, a leaf is not a cell. A leaf is an organ of a plant that is made up of multiple types of cells, including stomatal cells, epidermal cells, and chloroplast-containing cells. Cells are the basic structural and functional units of living organisms, including plants like leaves.
How does most carbon dioxide reach the photosynthesising cells of a green leaf?
Carbon dioxide enters the leaf through small pores called stomata located primarily on the underside of the leaf. Once inside the leaf, carbon dioxide diffuses into the cells containing chloroplasts, where photosynthesis occurs. This process allows the plant to convert carbon dioxide into sugars using light energy.
In which part of a leaf is a food made?
Food is made in any cell containing chloroplasts. The greatest contribution is by the pallisade cells on the upper surface of the leaf.
Where in a leaf would you expect to find palisade cells?
Palisade cells are typically found in the upper layer of a leaf called the palisade mesophyll. They are located directly beneath the upper epidermis and are responsible for carrying out photosynthesis due to their high concentration of chloroplasts.
Where in the leaf does almost all photosynthesis occur?
Almost all photosynthesis occurs in the chloroplasts, specifically in the chlorophyll molecules located in the mesophyll cells of the leaf. The mesophyll cells are located in the middle layer of the leaf, where they are well exposed to light.
Which cells would you expect to have the most chloroplast?
Cells in plant leaves would be expected to have the most chloroplasts because they are specialized for photosynthesis. Specifically, the palisade mesophyll cells located in the upper layer of the leaf would have the highest concentration of chloroplasts due to their role in capturing sunlight for photosynthesis.
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.
Does a leaf have cells?
Yes, a leaf has cells. They have A LOT of cells
Where are the palisade mesophyll cells located?
Palisade mesophyll cells are located in the upper layer of the leaf tissue called the mesophyll. They are typically found just beneath the upper epidermis of the leaf in plants. Their role is in photosynthesis, where they absorb light energy and carry out the process of photosynthesis.
Palisade cells are located near the top surface of the leaf for maximum absorption of what?
Sunlight
