Real Plant Parts & Their Functions practice questions
Which three things do leaves need to make food for the plant?
Sunlight, water and air ✓
Insects, rain and darkness
Soil, wind and moonlight
Fruit, seeds and pollen
Leaves combine sunlight, water (from the roots) and air to make food that helps the plant grow.
Why are most leaves broad and flat?
To absorb more water from the soil
To attract more insects
To make the plant heavier
To absorb as much sunlight as possible ✓
A broad, flat shape gives leaves a large surface area to catch more sunlight for making food.
Why are many flowers brightly coloured and scented?
To attract insects and other animals that help with pollination ✓
To scare away animals that eat plants
To absorb more sunlight for the plant
To help the plant absorb water faster
Bright colours and scents attract insects such as bees, which help transfer pollen between flowers so seeds can form.
After a flower is pollinated, what does it usually develop into?
A wider stem
A larger leaf
A new root
A fruit containing seeds ✓
Once pollinated, a flower can develop into a fruit, which contains and protects the seeds inside.
