Hi guys, today we will be talking about plants. 00:00:00
In this case, we will focus on nutrition and respiration, what they eat and how they breathe. 00:00:04
We will start with nutrition. 00:00:13
Remember that the name of this process, the name of the process that plants do to make 00:00:17
their own food is photosynthesis. 00:00:23
It takes place mainly in the leaves. 00:00:27
Water is absorbed by the roots. 00:00:33
The water comes from the ground. 00:00:38
The chlorophyll, which is in the leaves, absorbs sunlight and this is why leaves are green. 00:00:44
Leaves also absorb the carbon dioxide and the plants release oxygen. 00:00:55
Let's see with a picture, you will see it much better. 00:01:07
This is the leaves, the water that comes from the roots, as we said, the sunlight that is 00:01:11
absorbed by the leaves, the carbon dioxide, which is absorbed by the leaves too, and the 00:01:20
oxygen is released to the air. 00:01:32
That is why plants are necessary. 00:01:36
The name of the food, which is the result of photosynthesis, is glucose. 00:01:39
Now let's continue with respiration. 00:01:46
We need two things for respiration, oxygen and food energy, which is called glucose. 00:01:49
This is what we will use, what plants will use for respiration. 00:01:59
Carbon dioxide and water is released into the air during respiration. 00:02:05
Let's see a picture, you will see it much better. 00:02:18
This is the leaves, the plant, the glucose, the energy that they need. 00:02:23
The oxygen is absorbed and the carbon dioxide is released, just like animals and human beings. 00:02:30
Hope it is also useful for you guys, see you soon, bye bye! 00:02:41
