Question

From the features given choose the type of plant-based on habitat for every given feature.

Thick waxy stem, short root, cone shape plant, sloping branches, small and spine-like leaves, hollow stem.

Answer 1

Thick waxy coating:

1. The thick waxy coating on the stem of the desert plants helps to prevent frequent transpiration.
2. The water in the plant can be retained for longer hours.
3. The plant will be hydrated and will not require a frequent water supply.
4. Examples of desert plants are palm trees and desert willow trees.

Short roots:

1. Aquatic plants have short roots to hold the stem of the plant in flowing water firmly.
2. It is not much concerned with water absorption.
3. They are required to float on the surface for better water absorption in leaves.
4. Examples of aquatic plants with short roots are lotus.

Cone-shaped plants:

1. Mountains are prone to heavy rains and snow; thus, the shape of the cone helps the rainwater and snow to slide off easily.
2. The conical shape of trees helps the snow to wear off, and the plants get exposed to sunlight.
3. The formation of the cone is an adaption for survival in cold places.
4. Examples of mountainous plants are pine, Maple, cedar oak, and deodar.

Sloping branches:

1. Mountains are prone to heavy rains and snow; thus, the slopping branches help rainwater and snow slide off easily.
2. The sloppy branches of trees help snow wear off, and the plants get exposed to sunlight.
3. Examples of trees with sloping branches include pine, conifers, etc.

Small or spine-like leaves:

1. Small or spin spine-likes expose fewer stomata; thus, lesser transpiration takes place, and plants survive in less water in the desert.
2. Spines are also known as reduced leaves.
3. It is seen in cacti.
4. The Spine is an adaption for survival in the desert.

Hollow stem – Aquatic plant

1. Few aquatic plants have hollow and spongy stems filled with air.
2. This makes them light and helps them to float on water and receive the needed amount of bright sunlight.
3. Lotus plants have hollow, extremely light stems. This helps the leaves to float on water.
