Here are the correct answers for your worksheet, with a quick explanation for each one to help you understand why.
1. Spinach is a \_\_\_\_\_\_ of a spinach plant.
*
Answer: D. Leaf
*
Why: When we eat spinach, we are eating the green, flat part of the plant that catches sunlight. That part is called the leaf.
2. Which part of a plant produces pollen?
*
Answer: C. Flower
*
Why: The flower is the reproductive part of the plant. Inside the flower, there are parts that make yellow dust called pollen, which helps the plant make seeds.
3. A tomato is a \_\_\_\_\_\_ of a tomato plant.
*
Answer: B. Fruit
*
Why: In science, if a part of the plant grows from a flower and has seeds inside it, it is called a fruit. Tomatoes have seeds inside, so they are fruits (even though we cook them like vegetables!).
4. Which part of a plant helps keep the plant in upright position?
*
Answer: A. Stem
*
Why: The stem is like the backbone of the plant. It is strong and holds the leaves and flowers up toward the sun. Without the stem, the plant would fall over on the ground.
5. What makes the color of leaves green?
*
Answer: A. Chlorophyll
*
Why: Leaves contain a special chemical called chlorophyll. This chemical absorbs sunlight to help the plant make food, and it reflects green light, which is why our eyes see the leaves as green.
6. Which of the following is the smallest part of a plant?
*
Answer: B. Plant cell
*
Why: Everything living is made of tiny building blocks called cells. You need a microscope to see them. Seeds, flowers, and leaves are all made of millions of these tiny cells stuck together, so the cell is the smallest part.
