Plants have adaptations that help them survive in many different environments.
300
The venus flytrap has the ability to trap and eat insects. What might this adaptation t ell you about its environment?
It suggests that there are many insects in its environment and that it is hard to get nutrients from other sources.
300
Which of these is not a true statement?
A. Roots anchor the plant in the ground.
B. Roots help capture light energy for photosynthesis.
C. Roots absorb nutrients and water from the soil.
D. Roots are covered by many hairs to increase surface area.
B. Roots help capture light energy for photosynthesis.
400
A trait that helps a plant survive in its environment is called an _____________?
Adaptation
400
Plant roots also grow downward, in the direction of the pull of ___________
Gravity
400
Why do some trees lose their leaves in the fall or winter?
To conserve water
400
Some trees have adapted to cold winter air by losing their leaves. What do you think would happen to trees if their leaves did not fall off before a cold winter?
The entire tree would freeze and die. In warm weather, the roots take in water and send it up to the leaves, where it is used for photosynthesis. The leaves use the water to make food that gets transported throughout the plant. If the leaves did not fall off, then water in the leaves might freeze and kill the leaves, stems, and maybe even the trunk and the roots. When the leaves fall off, the trees live on stored food until spring.
400
Plants that trap insects or other small animals are called carnivorous plants.Why must they still do photosynthesis?
Carnivorous plants get nutrients, but not energy, from organisms they trap. They get energy from sugars produced during photosynthesis.
500
Some stimuli that affect plants are __________?
Chemicals, heat, gravity, water, or light
500
What are some examples of tropisms?
Plant stems that grow upward, towards a source of light, and plant roots that grow toward a source of water.
500
What might happen if you brought a desert into a humid greenhouse?
The plant would probably die, because it does not have the right adaptations for the new environment.
500
How do plants survive in their habitats?
Plants have adaptations to help them get water and sunlight, reproduce and survive in their habitats.
500
