Velamen tissue is found in

  1. epiphytes

  2. hydrophytes

  3. xerophytes

  4. parasitic roots

  5. respiratory roots
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multiple choice

Mosses occur in moist places because

  1. they cannot grow on land

  2. their gametes fuse in water

  3. they lack vascular tisuue

  4. they lack root and stomata
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since moss gametophytes have no vascular system to transport water through the plant or waterproofing systems to prevent tissue water from evaporating, they live in a damp environment in which to grow, they require a surrounding of water to reproduce.
