In submerged hydrophytes, which of the following is present?
In submerged hydrophytes, which of the following is present? Correct Answer Air spaces
Explanation:
- Hydrophytes are plants that are either partially or fully submerged into water.
- Partially submerged hydrophytes like Lilly have stomata present on their upper leaf surface (lower pat is submerged in water).
- Fully submerged hydrophytes like water ferns do not have stomata, instead of stomata, the plant's surface cells are capable of absorbing water, nutrients, and dissolved gases in the water.
- Aerenchyma are the spaces or air channels in the leaves, stems and roots of Hydrophytes. It is an adaptation of hydrophytes, these air spaces provides buoyancy to the plants
Additional Information
- Cuticle: It is a thick layer present on the cells of xerophytes to prevent the loss of water
- Sclerenchyma: Sclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits. They are usually dead and without protoplasts.
- Vascular tissue: Xylem and phloem are collectively termed vascular bundles. These may or may not have cambium
