Diversity in the Living World Class 6 Science MCQ Questions with Answers | CBSE Curiosity Book Chapter 2

Leaves are the food factories of the plant, performing photosynthesis to synthesize food. They also have tiny pores called stomata which help in the loss of excess water through a process called transpiration.

Ponds, deserts, and jungles are naturally occurring habitats. Cultivated land is an artificial, human-made environment created specifically for agriculture and rearing domestic animals.

Plants with fibrous roots generally have leaves with parallel venation (like grass, wheat, and maize). Plants with tap roots generally have leaves with reticulate venation (like rose and peepal).

Trees are tall plants with a thick, hard, and woody stem called a trunk. Herbs have soft, green stems, and shrubs have hard but relatively thin stems with branches near the base.

A lemon plant is a shrub because it is medium-sized, has a hard woody stem, and its branches start from near the base of the stem. Spinach and tomatoes are herbs, while mango is a tree.

A streamlined body shape offers the least resistance to the flow of water, making it easier to swim. Slippery scales protect the body. These are typical adaptations of aquatic animals like fishes.

All living organisms share common characteristics: they need food for energy, respire to release that energy, respond to changes in their surroundings (stimuli), and reproduce to continue their species.

There is a direct correlation between root systems and leaf venation. Plants with fibrous roots exhibit parallel venation, while plants with taproots exhibit reticulate venation.

To survive in arid conditions, desert plants are adapted to lose very little water (often having leaves reduced to spines) and have root systems that go very deep into the soil to absorb scarce ground water.

Wheat, sugarcane, and maize are grasses with fibrous roots and parallel venation. A Peepal tree has a taproot system, so its leaves exhibit reticulate (net-like) venation.
