What is spongy mesophyll layer?
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
Why are mesophyll cells are named so?
Mesophyll cells are named as such because they are located in the mesophyll layer of plant leaves. This layer is where photosynthesis primarily occurs, as it contains a high concentration of chloroplasts in the mesophyll cells to help with the process of converting sunlight into energy.
Why are the cells of the palisades layer packed so tightly togehter?
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through.
Why are cells of the spongy layer packed so loosely together?
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
Which region contain greatest number of chloroplast in a plant?
The region of a dicot leaf where most of the chlosoplast is found is in the palisade mesophyll because this is where the sunlight gets trapped so most the chlorophyll need to be present here so that photosynthesis can occur.

Why are cells of the palisades layer packed so tightly together?
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through. Tightly packed palisade cells is one way in which leaves are adapted for photosynthesis.

Why are the cells of the spongy layer packed so loosly together?
Because you cannot live in them. For instance, if they were packed tightly together, they would be called apartments. My question is why are they called apartments when they are all stuck together?
What element are present in solid liquid and gas state?
in solids molecules are tightly packed in liquid molecules are not so tightly packed whereas in gas they are free to move
What do the particels in a solid do?
they dont do anything. they are so tightly packed they cant do anything.
How much movement is there in the particles of solids?
they just vibrate as they are packed so tightly.
What is the function of palisade mesophyll cell?
Palisade cells are the main photosynthesis centers in a plant. They form the upper surfaces of leaves and contain many chloroplasts.They are important in producing energy through photosynthesis.
How are particles spaced in a solid?
Particles in a solid are tightly-packed, so there is no movement at all, therefore no space.
Why are cells of the spongy layer packed so loosely together?
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
What is a substance whose matter is more tightly packed than other another substance have a greater density or mass?
A substance with matter that is more tightly packed will generally have a greater density compared to a substance with less tightly packed matter. Density is a measure of mass per unit volume, so substances with denser matter will have more mass in a given volume.
