float
Match the aquatic plants with their adaptations:
Water lily = Waxy leaves Water hyacinth = Air spaces in the swollen leaf stalk Water fern = Hairs on the leaves that trap air
What is meant by structural adaptations?
The physical characteristics of an organism that help it survive in its natural habitat
Organisms that are adapted to their environment will either have to move to a different habitat or die.
False
What is one way plants adapt to conserve water in hot environments?
Having needle-like leaves to reduce surface area and water loss
Having a _______________ body shape helps animals adapt to moving in water.
streamlined
Match the following adaptations with their respective environments:
Having large ears to lose excess body heat = Hot environments Having closely packed feathers or thick fur and a layer of fat under the skin to trap air and stay warm = Cold environments Having air tubes that extend above the water surface = Underwater Having good night vision = Dark environments
Climbing on supports is an adaptation of aquatic plants to obtain sunlight.
False
What is one way animals adapt to breathing underwater?
Having gills to take in oxygen from water
Having strong, _______________ stems helps land plants adapt to obtain sunlight.
woody
What is meant by behavioural adaptations?
The special ways an organism behaves to survive in its natural habitat
Plants can survive without sunlight.
False
Study Notes
Types of Adaptations
- Structural adaptations: physical characteristics that help an organism survive in its natural habitat
- Behavioural adaptations: special ways an organism behaves to survive in its natural habitat
Adaptations for Survival
- Organisms that are adapted to their environment can cope with factors such as temperature and light, get air, water, and food, and protect themselves from predators
- Organisms that are not adapted to their environment will either have to move to a different habitat or die
Adaptations for Hot Environments
- Having large ears to lose excess body heat
- Avoiding the Sun's heat by staying underground or in the shade during the day
- Obtaining water from plant parts that they eat
- Feeding on the nectar or sap of plants
- Sweating and urinating very little to conserve water
- Having needle-like leaves in the form of spines to reduce surface area and water loss
- Having thick fleshy stems that store water
- Having roots that spread out over a wide area to absorb as much water as possible
Adaptations for Cold Environments
- Having closely packed feathers or thick fur and a layer of fat under the skin to trap air and stay warm
- Travelling long distances to avoid the cold weather
- Hiding and resting during winter to conserve energy
- Having needle-like leaves to reduce water loss
- Shedding leaves to survive the winter
Adaptations for Breathing Underwater
- Having air tubes that extend above the water surface
- Using moist skin to absorb oxygen
- Having gills to take in oxygen from water
- Trapping air bubbles
- Having nostrils or blowholes at the top of the body to breathe
Adaptations for Moving in Water
- Having a streamlined body shape
- Having special body parts like webbed feet, fins, and flippers
Adaptations for Flying
- Having well-developed wings
- Having feathers
- Having a streamlined body shape
- Having strong, hollow bones
Adaptations for Living in Dark Environments
- Having good night vision
- Having body parts that can light up
Adaptations for Obtaining Sunlight
- Having strong, woody stems to hold up branches and leaves
- Climbing on supports like walls, fences, or other plants
- Creeping along the ground with stems that spread out
- Having leaves that float on the water surface or extend above it
- Having waxy leaves that repel water
- Having air spaces in the leaf stalks
Adaptations of Aquatic Plants
- Some aquatic plants float or have leaves above the water surface to obtain sunlight
- Having large waxy leaves that allow water to run off
- Having air spaces in the swollen leaf stalk to help the plant float
- Having hairs on the leaves that trap air to allow the leaves to float on the water surface
This quiz covers the different types of adaptations in organisms, including structural and behavioural adaptations, and how they help organisms survive in their natural habitats.
