Aerenchyma is a specialised type of which tissue that contain air spaces
Answers
Answer:
Parenchyma
Explanation:
Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root. The channels of air-filled cavities provide a low-resistance internal pathway for the exchange of gases such as oxygen and ethylene between the plant above the water and the submerged tissues. Aerenchyma is also widespread in aquatic and wetland plants which must grow in hypoxic soils.
- They contain very large intercellular spaces. These are present in aquatic plants.
- Aerenchyma helps in the buoyancy of the floating plants
- It helps in the respiration and provides sufficient oxygen to the aquatic plants
- The aerenchyma formation takes place naturally in the roots of rice (Oryza sativa)
- The aerenchyma of leaves and stems of aquatic plants are large longitudinal cells with air spaces or lacunae, which are gas-filled
- Aerenchymatous cells are often water-filled
- Aerenchyma cells are continuous from shoots to roots and help in diffusion of air from leaves to roots. It helps in maintaining sufficient oxygen levels for respiration.
- The excess oxygen consumed, diffuses out from the roots into the soil atmosphere
- They help in creating locally aerobic rhizosphere in the anaerobic soil
