The Plant Kingdom: Characteristics and Classification

Hello friends! Welcome to a new Happy Learning video.
Today, we are going to learn about the importance of plants, their main characteristics and also, their classification. Presenting… The plant kingdom!
You already know that plants can’t move from one place to another, as you can see in these images, the great majority are held to the ground by roots, but they fulfill the vital functions of all living things: they are born, they grow, reproduce and die.
As you can see in these images, there are many types of plants, but… Do you know how many types there are? Well, according to scientists there are approximately 9 million different species. Some are gigantic, like this tree, that’s capable of producing shade for 100 people, at the same time! Others are tiny, like this miniscule flower… but although they may be different, they all have something in common… they are able to make their own food.
Plants don’t feed off other living creatures, like animals do, but they make their own food, thanks to photosynthesis, a process that transforms sunlight and inorganic matter in their surrounding, into food.
Photosynthesis is super important for plants, but for all living things too! Because in that process they release oxygen into the world… and without oxygen, none of us would be here today watching this video. Are plants important or what?
Plants were one of the first forms of life that appeared on earth, thanks to their capacity not to depend on other living creatures to survive.
Their most predominant colour is green, and this colour is called chlorophyll, an essential substance to perform photosynthesis.

As we said, there are many types of plants, and we can classify them in four large groups to get to know them better: algae, mosses, ferns and phanerogams.
Algae don’t have roots, stems or leaves. They live in water, both in rivers and seas, and they are the simplest plants.
Mosses are also simple plants. They live on solid ground but need a lot of humidity. They don’t have roots to absorb water in the ground because they live in very humid and bleak places.
Ferns are higher plants and their body is divided into roots, which is where they absorb water from the soil, stem, which is where the water circulates, and leaves, that grow upwards from the stem.
Phanerogams, despite their name, are the most common plants, because they reproduce through their flowers. They are higher plants and their bodies are divided into roots, stem and leaves. Trees are an example that belong to this group.
Well, now we know a bit more about plants and their importance towards all other living things. So you know that we need to take care of them, and respect them.
