Questions

1. What is the first stage of a plant's life cycle?

   1. Flower
   2. Seed
   3. Leaf
   4. Fruit
   Show answer

   Answer: Seed

   Every plant begins as a seed — a tiny protective case with a baby plant and stored food inside.

2. Plants can make their own food using sunlight.

   Show answer

   Answer: True

   Plants are unique — they can produce their own food through photosynthesis using sunlight, water, and carbon dioxide.

3. The underground part of a plant that absorbs water is the ___.

   Show answer

   Answer: root

   Roots grow underground, where they anchor the plant and absorb water and nutrients to send up through the stem.

4. Which part of a plant holds it upright and carries water?

   1. Leaf
   2. Flower
   3. Stem
   4. Seed
   Show answer

   Answer: Stem

   The stem is the plant's backbone — it supports the leaves and flowers and acts as a highway for water and nutrients.

5. Plants need sunlight, water, soil, and air to grow.

   Show answer

   Answer: True

   All four are essential — sunlight for energy, water for nutrients and hydration, soil for anchor and minerals, air for carbon dioxide.

6. What do we call it when a seed begins to sprout?

   1. Evaporation
   2. Germination
   3. Migration
   4. Hibernation
   Show answer

   Answer: Germination

   Germination is when a seed absorbs water and begins to grow — sending a root down and a shoot up toward the light.

7. Plants make food using sunlight in a process called ___.

   Show answer

   Answer: photosynthesis

   Photosynthesis happens in the green parts of plants (mostly leaves) — chlorophyll captures sunlight to turn CO2 and water into sugar.

8. A plant would grow well in complete darkness.

   Show answer

   Answer: False

   Without sunlight, plants cannot photosynthesize and make food — they would eventually wilt and die.

9. What do plant roots absorb from the soil?

   1. Sunlight
   2. Air
   3. Water and nutrients
   4. Flowers
   Show answer

   Answer: Water and nutrients

   Root hairs absorb water and dissolved minerals from the soil, which travel up the stem to feed leaves and flowers.

10. Flowers help plants make new seeds.

    Show answer

    Answer: True

    Flowers contain the reproductive parts of the plant — after pollination, they produce seeds for the next generation.
