Xerophytes possess

  1. Sunken stomata

  2. Deep roots

  3. Thick cuticle

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Xerophytes employ multiple strategies to conserve water, including sunken stomata to reduce transpiration, deep root systems to access water, and a thick waxy cuticle to prevent water loss.

Ephemerals are a type of xerophytes ______________.

  1. Drought escaping

  2. Drought resisting

  3. Drought enduring

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ephemerals are classified as drought escaping plants because they avoid the drought period entirely by existing as dormant seeds.

What is wrong about xerophytes?

  1. Sunken stomata

  2. Small spiny leaves

  3. Thick cuticle

  4. Larger number of stomata
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Xerophytes minimize water loss by reducing the number of stomata or having them sunken. A larger number of stomata would increase transpiration, which is detrimental to a plant in a dry habitat.

A non-succulent xerophyte with thick leathery leaves having white sticky waxy coating is

  1. Nerium

  2. Calotropis

  3. Bryophyllum

  4. Ruscus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Calotropis is a non-succulent xerophyte that features thick, leathery leaves covered in a white, waxy, or hairy coating to reduce water loss and reflect sunlight.

In xerophytes, photosynthesis often occurs through

  1. Root

  2. Modified stem

  3. Stomata

  4. Scaly leaves
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In many xerophytes, leaves are reduced to spines to prevent water loss. Consequently, the stem becomes green and photosynthetic (cladode or phylloclade) to perform the function of leaves.

Which ones develop characteristics of xerophytes?

  1. Hydrophytes

  2. Sciophytes

  3. Heliophytes

  4. Halophytes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Halophytes grow in saline environments where water uptake is difficult due to high salt concentrations, leading to physiological drought. Thus, they often develop xerophytic adaptations.
