Cuticle in xerophytes acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The aerial organs in xerophytes are covered, thick, waxy covering called cuticle. The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature.
So, the correct option is 'True'.

Green plants are absent in deep sea. Why?

  1. Light is absent

  2. High pressure

  3. Low temperature

  4. Great depth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis, which is essential for green plants, requires light. In the deep sea, light cannot penetrate, making it impossible for green plants to survive.

Effect of $O _{3}$ in plants, involve:

  1. Stomata burning

  2. Oxidizing burning

  3. Reduced survival

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

Ozone (O3) is a strong oxidant that can cause damage to plant tissues, including burning of stomata, oxidative stress, and reduced survival rates.

Most animals and plants can grow with pH, between

  1. 4 and 9

  2. 5 and 9

  3. 6 and 9

  4. 7 and 9
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Most plants and animals have evolved to thrive within a relatively neutral pH range, typically between 5 and 9, as extreme acidity or alkalinity interferes with biological processes.

_________ plants have flattened leaf-like stems to carry out photosynthesis.

  1. Prickly pear

  2. Potato

  3. A & B

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

In Opuntia (prickly pear), the stem is modified to a flattened green structure to perform the function of leaves. Leaf-like flattened modified stems are called phylloclades. 


So the correct option is "Prickly pear".

Nitrates, phosphates and sulphates are plants

  1. Disease

  2. Pollutants

  3. Nutrients

  4. Organic pollutants
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nitrates, phosphates, and sulphates are essential inorganic compounds that plants absorb from the soil to synthesize proteins and other vital molecules, thus acting as nutrients.
