What is the main function of the palisade layer in a leaf?
The palisade mesophyll layer of the leaf is adapted to absorb light efficiently. The cells: are packed with many chloroplasts. are column-shaped and arranged closely together.
Where is palisade found in a leaf?
The palisade parenchyma tissue usually is located on the upper side of the leaf, and the spongy parenchyma on the lower side. There may be only a single layer of palisade cells perpendicularly arranged below the upper epidermis, or there may be as many as three layers.
Why is the palisade layer at the top of the leaf?
The palisade layer contains the most chloroplasts as it is near the top of the leaf. The chloroplasts contain the pigment chlorophyll. The palisade cells are arranged upright. This means the light has to pass through the cell lengthways and so increases the chance of light hitting a chloroplast and being absorbed.
What is palisade function?
The palisade cell can be found in the upper part of all leaves. Their function is to enable photosynthesis to be carried out efficiently and they have several adaptations.
How does the palisade layer help photosynthesis?
Palisade cells help to absorb the sunlight for the photosynthesis process with the help of chlorophyll. Palisade cells are long and cylindrical in a structure that contains a large number of chloroplasts.
How is the palisade tissue layer structured?
This layer (palisade layer) is located beneath the upper epidermis and is composed of cells that are columnar/cylindrical in shape. In addition to a nucleus, some of the other important organelles of palisade cells include a cell membrane, a large vacuole, chloroplasts as well as a cell membrane among a few others.
What is beneath the palisade layer?
Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis. They are irregularly shaped cells that have many intercellular spaces that allow the passage of gases.
How is a leaf palisade cell adapted to its function?
What are the layer of a leaf?
Structure-Function Relationship: Leaves
| Name of Structure | Structure |
|---|---|
| Cuticle | Layer of suberin |
| Epidermis | Single layer of thin, closely packed cells |
| Guard cells | Spiral walls, bound at ends |
| Palisade cells | Tall, many chloroplasts, precisely spaced |
Why does the palisade layer contain the most chloroplasts?
The palisade layer contains the most chloroplasts as it is near the top of the leaf. The palisade cells are arranged upright. This means the light has to pass through the cell length ways and so increases the chance of light hitting a chloroplast and being absorbed.
