QUESTION 1
What does a seed need to start growing?
Water, warmth, and air (and then sunlight to keep growing).
QUESTION 2
What part of a plant makes new seeds?
The flower, after it is pollinated.
QUESTION 3
Why is a plant's life called a cycle?
Because the new seeds grow into plants that make more seeds, so it repeats again and again.

Create: draw the life cycle.

Have students draw a seed, a sprout, a grown plant, and a flower, then add arrows in a circle to show how the cycle repeats. A printable plant life-cycle worksheet is in the Science library.

Answer key — Part A: 1) sprout · 2) seedling · 3) pollination · 4) roots · 5) germinate · 6) flower · 7) life cycle · 8) seed
Part B: 1) Water, warmth, and air (and then sunlight to keep growing). 2) The flower, after it is pollinated. 3) Because the new seeds grow into plants that make more seeds, so it repeats again and again.
