Question

what are the adoption seen in hydrilla plant ??​

Answer 1

Step-by-step explanation:

The leaves are thin, long and ribbon shaped to provide least resistance to the flow of water 8. The roots are either poorly developed, they only needed for anchorage, not for absorption of nutrients and water 9. Plants produce seeds that can float 10. The whole plant is covered over by mucilage.

Hydrilla – Ecological Adaptations

• Hydrilla is also known as water thyme, scientifically it is named as Hydrilla verticillata (L.f.)
• Royle Hydrilla’s scientific name is made up of the Greek word “hydro” meaning “water” and
• the Latin word “verticillus” that means “the whorl of a spindle”. Appropriately named, it is
• an aquatic plant with leaves that are whorled around the stem. Hydrilla is in the Frog’s Bit
• family, or Hydrocharitaceae. It is the only species of the genus Hydrilla in the world though it
• resembles many of the other species in the family.

Ecological Adaptations:

Morphological :

1. It is a submerged hydrophyte found attached to the substratum by adventitious roots

in fresh water ponds.

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.

3. Peculiar hairs are presents on leaf and stem

4. Leaves are whorled, 5 in bunch

5. Leaf is roughly textured

6. The stem is long, slender, spongy and flexible to move with water currents

7. The leaves are thin, long and ribbon shaped to provide least resistance to the flow of water

8. The roots are either poorly developed, they only needed for anchorage, not for

absorption of nutrients and water

9. Plants produce seeds that can float

10. The whole plant is covered over by mucilage. It prevents epiphytic growth .
