Section B: Short Answer Questions
- The four main parts are roots, stem, leaves, and flowers.
- The main function of the heart is to pump blood to all parts of the body.
- Leaves are important because they make food for the plant through photosynthesis.
- The skeleton gives the body shape/support and protects the organs.
- A seed needs water, warmth, and air to sprout and grow.
- The stomach helps to break down and digest food.
- The five senses are sight, hearing, smell, taste, and touch.
- Plants need sunlight as energy to make their food.
- The skull protects the brain.
- The flower part of the plant becomes a fruit.
- Our bodies need lungs to take in oxygen from the air and get rid of carbon dioxide.
- Roots anchor the plant in the soil and absorb water and nutrients.
- The heart and lungs are found inside the chest.
- Flowers are brightly coloured to attract insects like bees for pollination.
- The root usually grows underground and absorbs water, while the stem grows above ground and supports the plant.
- Muscles help us move by pulling on our bones.
- You are eating the leaves of the spinach plant.
- The main bone is the spine or backbone.
- Stems support the leaves and flowers, and transport water and food through the plant.
- Both humans and plants need water and nutrients to live and grow. (Other similar answers are acceptable).
Section C: Problem Solving
- The seed in Pot A will grow into a healthier plant. Both need water, but the plant in Pot A also gets sunlight, which it needs to make food and be healthy.
- He is also using his lungs to breathe hard and get oxygen, and his heart to pump blood and oxygen to his muscles. His brain is controlling all his movements. (Any two are acceptable).
- Carrots are a root, broccoli is a flower (or flower bud), and sunflower seeds are seeds.
- Two possible reasons are: 1) It is not getting enough water. 2) It is not getting enough sunlight.
- The metal frame or chassis of the robot would be like the skeleton. Its job would be to give the robot its shape and support all the other parts.
- Yes, they are both fruits. A fruit is the part of the plant that holds the seeds, and both apples and strawberries hold seeds.
- A human needs a heart to pump life-giving blood to every part of the body. A plant doesn't need a flower to live; the flower's job is just to make seeds for new plants. The leaves, stem, and roots are essential for the plant to survive.
- If a tall tree had a weak stem, it would likely fall over, especially in the wind. It would not be able to support its branches and leaves.
- The brain sent the message to move your hand. You used the sense of touch.
- This plant likely lives in a dry environment. The large, deep roots help it search for and find water deep under the ground where the soil is not as dry.
