Here are two types of seeds. What differences do you find among the roots and leaf venation of their plants? (a) Wheat (b) Kidney beans

Wheat is a monocot seed (one cotyledon). Monocot plants have fibrous roots and parallel venation in their leaves.

Kidney beans are a dicot seed (two cotyledons). Dicot plants have a taproot system and reticulate (net-like) venation in their leaves.

So the two plants differ in both root type (fibrous vs taproot) and leaf venation (parallel vs reticulate).

Answer: Wheat: fibrous roots + parallel venation. Kidney beans: taproot + reticulate venation.

Manu's mother maintains a kitchen garden. One day, she was digging out radish from the soil. She told Manu that radish is a kind of root. Examine a radish and write what type of root it is. What type of venation would you observe in the leaves of radish plant?

Radish is a dicot plant. Dicot plants have a taproot system — one main root with smaller side roots branching from it.

The radish we eat is actually a modified taproot that stores food.

Since radish is a dicot, its leaves have reticulate (net-like) venation.

Answer: Radish has a taproot system. Its leaves show reticulate venation.

Look at the image of a mountain goat and a goat found in the plains. Point out the similarities and differences between them. What are the reasons for these differences? (a) Mountain Goat (b) Goat found in the plains

Similarities: Both are goats — they have four legs, a similar body shape, and eat plants.

Differences: Mountain goats tend to have thicker fur/coat to withstand cold temperatures, and their hooves are adapted for gripping rocky mountain surfaces. Goats found in the plains have thinner coats suited to warmer conditions.

Reasons: These differences are adaptations. The biodiversity and features of animals vary from region to region because of distinct environmental conditions. Mountain goats need features that help them survive cold climates and rocky terrain, while plains goats need features suited to warmer, flatter habitats.

Answer: Both are goats with four legs and plant-eating habits. Mountain goats have thicker fur and gripping hooves — adaptations for cold and rocky environments. Plains goats have thinner coats suited to warmer conditions. These differences are adaptations to their different habitats.
