This year we have studied in science and the ecosystem living things, these days we are studying the plants. Together with the teacher Margaret learned that plants, as living beings, are made of organs, including the leaf. The leaf is very important for the plant because it performs many functions such as breathing and perspiration. These functions are performed through the stomata, tiny openings that are scattered on the plate.
To better understand the perspiration we did an experiment: we took a transparent plastic bag and a basil plant, we wrapped up the plant in the bag and tied the ends with string, and after a few days we have seen of the droplets on the bag. This is because the Plants absorb water from the ground and returns in the form of steam, which condenses encountering the cold wall of the bag. We also did another little experiment to see how the 'water reaches the leaf. We have colored the water with the 'ink and we have absorbed a stalk of celery, a few days after we cut the celery and saw through the ribs, small tubes, the water has risen to colorful leaves, it also spent more days the highest leaves are colorful.
