  1. Prosopis, tree, scrub

  2. Saccharum, grass, forest

  3. Shorea robusta, herb, tropical rain forest

  4. Acacia catechu, tree, coniferous forest

A Correct answer
Explanation

Prosopis species are typically trees found in arid or scrubland environments, making this the most accurate match among the choices provided.

Plants like Rhizophora and Avicennia grow on the sea shores under saline conditions. For this they have special roots for respiration which are called

  1. Floating roots

  2. Pneumatophores

  3. Climbing roots

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

Pneumatophores are specialized root structures that grow out from the water surface and facilitate the aeration necessary for root respiration in hydrophytic trees such as many mangrove species (e.g., Avicennia germinans and Laguncularia raecemosa), bald cypresses, and cotton (Tupelo) gum (Nyssa aquatica). So, the correct option is "B" (Pneumatophores).

Choose the feature not associated with organism found in tropical deserts

  1. Small body size

  2. Large surface area relative to their volume

  3. Large body extremities

  4. Small surface area relative to their volume
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tropical desert areas are those where there is scarcity of water and extensive heat. Organisms in those areas adapt to survive in that ecological condition. Adaptations like thorns and succulents in flora helps the plants to survive without plenty of water. The leaves and stems undergo modification to conduct photosynthesis in less available water. Animals like frogs, rabbits, snakes, camels, etc. also go through modification in their characteristics to ensure their survival. Large surface of an any organism can lead to radiation of more body heat per unit of mass which can be fatal. Hence, such adaptations is not seen in organisms present in tropical desert.

So the correct option is 'large surface area relative to their volume'

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'.

Find the correct match.

  1. Halophyte - Wheat

  2. Xerophyte - Mustard

  3. Geophyte - Tomato

  4. Hydrophyte - Pistia
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Hydrophytes are plants adapted to living in aquatic environments; Pistia (water lettuce) is a classic example of a free-floating hydrophyte.

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".
