What is usually the first stage of a flowering plant's life cycle?
Seed
If you want to see how a Mung Bean Plant changes, what should you do?
Observe it. Look to see if there is an impact from more or less sunlight, more or less water.
Name two things that plants need to grow.
Water and sunlight (also air or nutrients)
What can happen to a plant if it does not get enough water?
It can dry up and die.
Where do plants get nutrients?
From the soil
What does a seed grow into?
A seedling / young plant
In the mung bean experiment, why were the two sprouts chosen to be the same size?
To make the experiment fair.
What do plants get from the soil?
Nutrients
Why do plants need sunlight?
They need sunlight to make food.
What part of the plant takes in water and nutrients from the soil?
The roots
What does an adult flowering plant produce?
Flowers
If one plant gets water and another does not, what are you testing?
If water helps plants grow.
Plants need four important things to grow. Can you name all four?

Two plants are the same size. One gets sunlight and one gets no sunlight. Which plant should grow better?
The plant that gets sunlight.

A student puts one mung bean sprout in light and another in a dark box. Both get water. What should the student compare after one week?

A plant has sunlight and water, but it has no nutrients. What might happen to the plant?
It may grow slowly and become small and weak.
Put these stages in the correct order: fruit with seeds, seed, adult plant with flowers, seedling, adult plant with fruits.
Seed → Seedling → Adult plant with flowers → Adult plant with fruits → Fruit with seeds
A plant in the dark grows poorly. A plant in the light grows well. What conclusion can the scientist make?
Light is important for plant growth.
