Q2: How do plants adapt to survive in deserts?

Plants in deserts often have fleshy stems to store water and may have spines instead of leaves to reduce water loss.

Q3: What is the importance of grouping plants and animals?

Grouping makes it easier to understand and study plants and animals on the basis of their similarities and differences. 

Q4: What are fibrous roots?

Fibrous roots are a type of root system where many thin roots spread out from the base of the stem, common in plants with parallel venation.MCQ & Extra Questions: Diversity in the Living World | Science Class 6

Q5: Give an example of an aquatic habitat and an organism that lives there.

An example of an aquatic habitat is a pond, and a fish is an organism that lives there.

Q6: What is the difference between terrestrial and aquatic habitats?

Terrestrial habitats are those found on land, while aquatic habitats are found in water bodies like ponds, lakes, and oceans.

Q7: What type of venation is found in the leaves of monocots?

Monocots typically have parallel venation in their leaves. In monocotyledonous (monocot) plants, the veins in the leaves run parallel to each other, forming a pattern where the veins are aligned along the length of the leaf. This is in contrast to dicotyledonous (dicot) plants, which typically have a reticulate (net-like) venation pattern where the veins form a branching network.

Q10: What type of roots does a mustard plant have?
a)
Fibrous roots
b)
Taproots
c)
No roots
d)
Aerial roots

Ans: b) Taproots

Mustard plants have a taproot system. In this type of root system, there is one main root, known as the taproot, that grows straight down into the soil. From this main root, smaller secondary roots branch out. Taproots help the plant access water and nutrients from deeper layers of the soil and provide strong anchorage to the plant.
