What are adaptive features of hydrilla?

Answer 1

1) leaves with narrow lamina to offer minimum resistance of water.

2) large air cavities with in the tissues to make it bouyont.

3) Xylem is poorly developed and no lignified as water can be absorbed easily from all sides

4) there is no cutical on it's leafs for easy absorbtion

Answer 2

the growth of hydrilla enables it to compete effectively for sunlight. It can elongate very rapidly, upto an inch a day..until it nears the water surface, where it gets sunlight.

i) It is a submerged hydrophyte found attached to the substratum by adventitious roots in fresh water ponds.

ii) The stem is soft and slender and bears thin and membranous leaves in whorls of 3-8.It limps when taken out of water showing the absence of any mechanical tissue.

iii) The leaves are arranged in such a way to provide least resistance to the flow of water. They lack cuticle and stomata.

iv) The whole plant is covered over by mucilage. It prevents epiphytic growth and protects the plant against the rotting effect of water.

Answer 3

Hydrilla has adaptive features such as rapid growth rates, extensive branching, and the ability to grow in diverse environmental conditions. It can also reproduce through fragmentation, allowing it to quickly colonize new habitats and outcompete native plant species. Additionally, hydrilla can survive under low light conditions by adjusting its photosynthetic rate to maximize efficiency.

Answer 4

Well it's a plant of course and it lives under water.

Answer 5

hydrilla is an plant with special species

Answer 6

it is a water plant
