Plant Nutrition and Respiration 00:00:11
Nutrition 00:00:14
How do plants make food for themselves? 00:00:19
Plants make their own food, called glucose, through a process called photosynthesis. 00:00:25
Photosynthesis takes place mainly in the leaves. 00:00:33
Water is absorbed from the soil by the roots and goes up to the stem to the leaves. 00:00:37
Leaves contain a green chemical called chlorophyll. 00:00:43
This absorbs energy from sunlight. 00:00:48
Leaves absorb carbon dioxide from the air. 00:00:52
During photosynthesis, plants release oxygen into the air. 00:00:56
Plants also need minerals for nutrition. 00:01:01
Minerals are absorbed in the water by the roots. 00:01:05
Respiration 00:01:10
How do the plants breathe? 00:01:10
Respiration gives the plant the energy it needs to grow and be healthy. 00:01:16
Plants use the glucose made through photosynthesis and oxygen for respiration. 00:01:22
During respiration, carbon dioxide and water is released into the air. 00:01:29
An interesting thing about plants is how photosynthesis and respiration work together. 00:01:35
During photosynthesis, plants produce oxygen and glucose. These are needed for respiration. 00:01:40
During respiration, plants release carbon dioxide and water. These are needed for photosynthesis. 00:01:47
All animals, including humans, need oxygen to live. 00:01:55
Plants give our planet oxygen through photosynthesis. 00:02:00
It is why trees and other plants are so important and we should look after them and not cut 00:02:04
them down. 00:02:10
