Plants in the Surroundings — Important Questions

Photosynthesis

Step 1: Green leaves act like the kitchen of the plant. Step 2: They use sunlight, carbon dioxide from air, and water from roots to make food. Step 3: This food-making process is called photosynthesis. Step 4: Germination is when a seed grows into a new plant. Respiration is breathing. Absorption is what roots do with water. Step 5: So the correct answer is Photosynthesis.

Petiole

Step 1: A leaf has several parts — leaf blade, midrib, veins, petiole, tip, and stomata. Step 2: The petiole is the stalk or the small stick-like part that joins the leaf to the stem. Step 3: The midrib is the main central vein in the middle of the leaf. Step 4: Stomata are tiny holes on the underside of the leaf. Step 5: The petiole connects the leaf to the stem, so it is the correct answer.

Stomata

Step 1: Leaves have tiny holes on their underside. Step 2: These holes are called stomata. Step 3: The leaf takes in carbon dioxide (air) through stomata during photosynthesis. Step 4: It also gives out excess water and oxygen through the stomata. Step 5: Veins carry water inside the leaf, midrib is the central vein, and petiole connects the leaf to the stem. So stomata is the correct answer.

To carry water and nutrients to all parts of the plant

Step 1: The stem has many important jobs in the plant. Step 2: It supports the plant and keeps it upright. Step 3: It also carries water and nutrients absorbed by the roots to the leaves and other parts. Step 4: Absorbing water is done by roots, making food is done by leaves, and attracting birds is done by flowers. Step 5: So the correct answer is carrying water and nutrients to all parts of the plant.
