Plants adapt to the environment in different ways.
Give one different way how different parts of the plant adapt explain what it does.
roots/stems/leaves (deserts/tropical rainforests/wetlands)
Deserts:
- Deep roots to absorb water deep in the ground.
- Shallow roots absorb water quickly.
- Thick stems to store more water.
- Needle-shaped leaves to reduce water loss.
Wetlands:
- Aerial roots to get more oxygen in the air due to the lack of oxygen in the soil.
- Stems have holes to facilitate gaseous exchange due to the lack of oxygen in the soil.
- Leaves are waxy to reduce water loss from high salt content and high sunlight.
Tropical rainforests:
- Buttress roots support trees to grow tall to get more sunlight.
- Stems twine around trees to climb tall and get more sunlight.
- Leaves are broad and smooth to get more sunlight and shed excess water.
Give two features of the following animals that help them get food.
- Giraffe
- Lion
- Hummingbird
- Mantis
- Pelican
Animal features that help them get food:
Giraffe: long necks to get food high up in trees. They also have a tough tongue and lip which prevents injury from sharp leaves.
Lion: Superb sense of sight, hearing and smell to help them hunt. Their sharp teeth and claws help tear prey apart.
Humming bird: They can flap their wings quickly and stay in the same position for a long time. The use their long and narrow beak to get nectar out of flowers easily.
Mantis: Huge compound eyes to give all-round vision to hunt prey. They also have spikes on their legs to help them catch prey.
Pelican: Sharp eyesight and good at swimming and flying. This makes it wasy for them to catch fish. They can store fish in their throat poach.
