Solid, liquid and gases are the three states of matter. All the three are of different properties and can be easily distinguished on the bases of the motion of their molecules, forces and the arrangement of the molecules. The molecules in the solid are closely packed and, therefore, have a strong intermolecular force, which gives […]

Stomata in the leaves of plants are situated in the position at the tip point, that is at the tip corner with a small opening which helps a plant to absorb carbon-dioxide. They also exhale oxygen out from leaves. This is the food for leaves which is done through stomata in plants and also water
In the layers of the tissues of animals and plants there is one layer where stomata lie. This layer is epidermal layer. Stomata are helpful for leaves. Rather, we can say to plants in a respiratory system. They allow leaves or rather a plant to breathe. Tissues in leaves breathe through stomata pores and then
