Why are the cells of the spongy layer so loosely packed together?

Why are the cells of the spongy layer so loosely packed together?

Spongy mesophyll tissue is packed loosely for efficient gas exchange. Gases dissolve in this water as they move into and out of the cells. When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them.

Why might the cells of the Palisades layer have more chloroplasts in them than the spongy layer?

Why are the cells of the palisades layer packed so tightly together? Why would the cells of the palisades layer have more chloroplasts in them? for more efficient photosynthesis. What is the function of guard cells?

In which cell layer palisade or spongy are the chloroplasts packed more tightly together?

Palisade mesophyll layer: Tightly packed layer of elongated cells located directly below the upper epidermis. These cells contain most of the chloroplasts in a leaf.

How is a palisade cell adapted to its function?

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.

Why are palisade mesophyll cells columnar?

This layer (palisade layer) is located beneath the upper epidermis and is composed of cells that are columnar/cylindrical in shape. Because of their shape (elongated and cylindrical) palisade cells contain many chloroplasts Palisade cells contain 70 percent of all chloroplasts.

What is the function of the palisade layer in a leaf?

The palisade mesophyll layer is where most of the photosynthesis occurs in the leaf. The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis. The palisade cells are closely packed together to maximize light absorption.

How are the palisade and spongy cells arranged differently How do their arrangements relate to their functions?

Cells in the palisade layer are closely packed to absorb the most sunlight possible. Cells in the spongy mesophyll layer are more lossley packed to allow movement of gases requires for and produced by photosynthesis.

Why is palisade layer a tissue?

A tissue is a group of cells that coordinate to perform a particular action. The palisade layer of plant leaves is an example of such a tissue. This is because the cells of the palisade layer perform the function of trapping light and using it for photosynthesis.

Why is the shape of palisade cells important?

Because of their shape (elongated and cylindrical) palisade cells contain many chloroplasts Palisade cells contain 70 percent of all chloroplasts. This allows palisade cells to absorb as much as is needed for the process of photosynthesis.

Why are parenchyma cells packed tightly in the palisade layer?

Parenchyma cells are packed tightly in the palisade layer because it increases the efficiency of the plant. The more cells that are present, the more light that can be absorbed. Because light absorption is the first step in photosynthesis, absorbing more light means that the plant is able to produce more energy.

What is the palisade layer of a leaf composed of?

The palisade layer of a leaf is composed of parenchyma cells: this layer is where photosynthesis occurs. Parenchyma cells are present underneath the protective outer layer of the top of the leaf. Under the parenchyma cells is a layer of spongy cells that are loosely packed to allow gases and…

Why are the cells of spongy layer packed so loosely together?

To maximize the amount of light that is absorbed Why are the cells of the spongy layer packed so loosely together? To have a high increase of gas exchange What is the function of the xylem? transports water and soluble mineral nutrients from the roots throughout the plant What is the function of the phloem?

Why are the epidermis coated in a waxy cuticle?

Why are the epidermis layers of the leaf coated in a waxy cuticle? It helps conserve water Why are the cells of the palisades layer packed so tightly together? To maximize the amount of light that is absorbed Why are the cells of the spongy layer packed so loosely together?
