A colorful, easy-to-follow worksheet about plant parts, needs, growth, and problem solving
| # | Answer | Explanation |
|---|---|---|
| 1 | Roots absorb water and minerals and help anchor the plant in the soil. | Roots hold the plant in place and take in water and nutrients from the ground. |
| 2 | Leaves | Leaves are the main place where photosynthesis happens. |
| 3 | nutrients (or minerals from the soil) | Plants need minerals or nutrients from soil in addition to sunlight, water, and air. |
| 4 | True | The stem carries water and other materials through the plant. |
| 5 | Possible answers: water, sunlight, air, nutrients, or space to grow. | Any one basic plant need is correct. |
| 6 | Flower | Flowers help plants reproduce and often become fruits that contain seeds. |
| 7 | Root = absorbs water; Leaf = makes food; Stem = supports the plant | Each plant part has a different important function. |
| 8 | The plant is responding to sunlight or light. | Plants grow toward light so they can make food. |
| 9 | photosynthesis | Photosynthesis is how plants use sunlight, water, and carbon dioxide to make food. |
| 10 | False | Different plants need different amounts of water. |
| 11 | Seed coat | The seed coat is the outer covering that protects the seed. |
| 12 | Sample answer: Roots absorb water and hold the plant in the soil, while leaves make food. | A correct answer should compare the jobs of the two parts. |
| 13 | The plant may wilt, dry out, and stop growing well. | Without water, plants cannot carry out important life processes. |
| 14 | B) Stem | The stem helps move water and support the plant. |
| 15 | seedlings | A seedling is a young plant after germination. |
| 16 | Germination is when a seed begins to grow into a new plant. | Germination is the first stage of plant growth from a seed. |
| 17 | B) Flower | Flowers help the plant make seeds. |
| 18 | False | Plants need air, especially carbon dioxide, to make food. |
| 19 | It helps the cactus store water and reduce water loss. | These features are adaptations for dry environments. |
| 20 | Leaves | Leaves capture sunlight for photosynthesis. |
| 21 | The sunny field gives the plants more light for photosynthesis. | More sunlight usually helps plants make more food. |
| 22 | B, C, A | A seed usually absorbs water first, then the root grows, and then the seedling develops. |
| 23 | Roots | Roots usually grow below the soil surface. |
| 24 | Sample answer: Leaves make food for the plant through photosynthesis. | Leaves are the plant’s main food-making structures. |
| 25 | oxygen | During photosynthesis, plants release oxygen into the air. |
| 26 | The plant did not get enough light. | Without enough light, plants cannot make food well. |
| 27 | True | Many fruits protect seeds and help animals or wind spread them. |
| 28 | The plant may have trouble getting water and minerals. | Damaged roots cannot absorb resources well. |
| 29 | B) Plants need water to stay healthy | Plants need water for many life processes. |
| 30 | Possible answers: give it enough sunlight, water it regularly, use good soil, and place it where it has space to grow. | Healthy plant care includes meeting basic needs like light, water, and nutrients. |
