Plant Adaptations and Survival Strategies

The video discusses how plants adapt to various environments, such as deserts and rainforests, by developing special features over time. It explains the concept of native and introduced plants, highlighting how some introduced species become invasive. The video also covers plant breeding, which helps plants adapt more quickly to new conditions, ensuring better survival and crop yield.

What are the basic needs of plants to survive in different habitats?

• Light, air, water, nutrients, and space

• Air, soil, water, and temperature

• Food, shelter, water, and sunlight

• Sunlight, soil, water, and animals

Why do some desert plants have long roots?

• To anchor themselves in the sand

• To find water deep in the soil

• To absorb more sunlight

• To store nutrients

What adaptation helps rainforest plants deal with excess water?

• Thick bark

• Drip tips on leaves

• Waxy leaf coating

• Deep roots

What is a key feature of plant adaptations in shady rainforest environments?

• Small, thick leaves

• Big, spiky leaves

• Deep, narrow roots

• Brightly colored flowers

What is the term for plants that have developed special features over time to live in a specific habitat?

• Native plants

• Invasive plants

• Introduced plants

• Hybrid plants

What is the impact of invasive plants on native species?

• They have no impact on native plants

• They compete with and can overtake native plants

• They only affect animal populations

• They help native plants grow

Why did wheat from Europe initially struggle to grow on the Canadian prairies?

• It needed more sunlight

• It took too long to grow and froze

• It required too much water

• It was eaten by local wildlife

What process did farmers and scientists use to develop a new variety of wheat for the Canadian prairies?

• Natural selection

• Plant breeding

• Genetic modification

• Cross-pollination

How do plants naturally adapt to changes in their environment?

• Over a long period of time

• Through rapid genetic changes

• By changing their color

• By moving to a new location

What role do farmers and scientists play in plant adaptation?

• They only study plant failures

• They remove non-adaptive plants

• They help plants adapt more quickly

• They prevent plants from adapting
