Aquatic and Terrestrial Plants Concepts

The video tutorial covers different types of plants based on their habitats. Terrestrial plants grow on land and adapt to various environmental conditions. In hilly areas, plants are tall with needle-like leaves to shed snow. Desert plants survive with minimal water due to special adaptations. Aquatic plants are categorized into floating, fixed, and underwater types. Floating plants have spongy bodies to float, while fixed plants have roots anchored in the soil with flexible stems to withstand water currents.

What are terrestrial plants?

• Plants that grow in deserts

• Plants that grow in the air

• Plants that grow on land

• Plants that grow in water

Why do trees in cold hilly areas have needle-like leaves?

• To absorb more sunlight

• To prevent water loss

• To allow rain and snow to slide off easily

• To attract pollinators

What is a unique feature of desert plants?

• They grow in cold climates

• They can survive with very little water

• They have broad leaves

• They require a lot of water

What feature helps fixed aquatic plants to withstand water currents?

• Thick leaves

• Flexible stems

• Heavy roots

• Broad flowers

Why do fixed aquatic plants have a waxy coating on their leaves?

• To prevent water from collecting on them

• To attract insects

• To absorb more sunlight

• To make them heavier
