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?
Meso- means middle. So mesophyll are the cells found in the middle of the leaf between the upper and lower epidermis.
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.
How can you describe the motion of the particles in a solid?
The particles are tightly packed so they vibrate.

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.
How are particles spaced in a solid?
Particles in a solid are tightly-packed, so there is no movement at all, therefore no space.
Does liquid takes the shape of it container?
Yes because its atoms are tightly packed so it has volume but no definite form.
How can you describe the motion of the particles in a solid?
The particles are tightly packed so they vibrate.
