Lesson Worksheet: Structural Adaptations Science

In this worksheet, we will practice defining a structural adaptation, describing examples of structural adaptations in plants and animals, and explaining how they aid survival.

Q1:

The stick insect (pictured) disguises itself within its environment. What is the main benefit of this?

The stick insect
  • AIt can hide from predators so that it is not eaten.
  • BIt can hunt other species of insects.
  • CIt can regulate its own body temperature better.
  • DIt can attract many mates.

Q2:

Ducks have webbed feet to help them swim through water in which they search for food.

Duck feet

Select the bird from the following pictures that is also well adapted to search for food in water.

  • A
    White swan
  • B
    Magpie (Pica pica) bird
  • C
    European Robin
  • D
    Owl

Q3:

A vulture has a sharp, crooked beak to tear flesh from its prey.

Griffon vulture

Choose the bird from the following pictures that also consumes meat.

  • A
    Male wild duck outside the water
  • B
    Pigeon
  • C
    Hawk's head
  • D
    Barn swallow bird

Q4:

The following are some examples of structural adaptations:

  1. Brightly colored leaves on flowers
  2. Strong, powerful, hind legs
  3. Skin or fur coloring that matches the environment
  4. A short and powerful beak to crush seeds
  5. Webbed feet to allow efficient swimming in water

Which of these structural adaptations helps organisms consume food?

Q5:

Some examples of structural adaptations are provided below:

  1. Brightly colored leaves on flowers
  2. Strong, powerful, hind legs
  3. Skin or fur coloring that matches the environment
  4. A short and powerful beak to crush seeds
  5. Webbed feet to allow efficient swimming in water

Which of these structural adaptations would help an organism quickly move away from a predator?

  • A2 only
  • B1, 3, and 4
  • C4 and 5
  • D5 only
  • E2 and 5

Q6:

Dolphins (pictured) have a structural adaptation of flippers. How does this adaptation help dolphins?

  • AIt helps them move through water.
  • BIt attracts mates for reproduction.
  • CIt keeps them cool.
  • DIt provides camouflage to help them hide from predators.

Q7:

Horses have been used throughout human history to work on farms, pulling heavy machinery, and to transport people and goods. Which of the following structural adaptations is the most useful for a horse to carry out these roles?

Horse
  • AThick, brown fur
  • BClean, glossy coat
  • CMany blunt teeth
  • DLong eyelashes
  • EStrong, powerful legs

Q8:

Some examples of structural adaptations are provided below:

  1. Brightly colored leaves on flowers
  2. Strong, powerful, hind legs
  3. Skin or fur coloring that matches the environment
  4. A short and powerful beak to crush seeds
  5. Webbed feet to allow efficient swimming in water

Which of these adaptations helps organisms hide from predators?

Q9:

Consider the following structural adaptations in mammals:

  1. Flippers and fins on whales
  2. Wings on bats
  3. Long arms on spider monkeys

What is the main reason for all of these adaptations?

  • ATo aid movement
  • BTo aid camouflaging in their natural habitat
  • CTo help consume food
  • DTo help capture prey

Q10:

Pitcher plants (pictured) have a deep flower, filled with liquid that has many digestive enzymes. When insects are attracted to the plant, they fall in. How does this benefit the plant?

Pitcher plants
  • AThe insects carry pollen to different plants to help reproduction.
  • BThe plant uses the insects to camouflage itself.
  • CThe plant digests the insects to obtain nutrients.
