What helps aquatic plants to float in water?
-In the aquatic plants a large air cavity is present in parenchyma cells that give buoyancy to the plants and help them to float in the water. This type of parenchyma cell is known as aerenchyma. -The aerenchyma cells of stems and roots serve as a storage centre for nutrients and water.
Can you guess how water plants are able to float on water?
The tissue which allows aquatic plants to float is Aerenchyma. The cells of aerenchyma make a network which has wide air spaces or air cavities for gaseous exchange. These air cavities make the plant light and buoyant and hence, plants can float easily in water.

Which plants do not have stomata?
Functional stomata are absent in submerged aquatic plants and in non-vascular land plants (for example, mosses) which are normally covered by a water film.
Which plants have more stomata?
In vascular plants the number, size and distribution of stomata varies widely. Dicotyledons usually have more stomata on the lower surface of the leaves than the upper surface. Monocotyledons such as onion, oat and maize may have about the same number of stomata on both leaf surfaces.
What plants have stomata?
Stomata occur in vascular plants. Vascular plants include the lower vascular plants such as horsetails (Equisetum), ferns (class Filicinae), gymnosperms, and angiosperms.
