'Characteristics of animals' Animal World Part-2

 Hello friends in this blog you are going to read about animals, so let's start.

Recap of previous article- 

1. Life on our Planet, which makes our planet unique.

2. Animals and Plants are two types of living organisms which play a very significant role in ecosystem.

3. Difference between plant and animal (in short).

======================

We all have seen trees, maybe in the park or besides our house, or anywhere else. The trees are huge and you will not find movement in them, only you can see their growth. But animals can move freely, this is one of the major difference between plants and animals, but we had already read this in the previous part. But what about small single-celled plants and animals? That's what we are going to know in  this article.

Generally plants can not move but some exceptions like swimming algae can move. The plants are called Autotrophs; as they produce their own food by the green pigment called chlorophyll, but animals  can't do that and depend on plants for food, and they are called Heterotrophs.

Animals have a nervous system that makes them sensitive to touch heat cold pain and other changes in environment (Stimuli). On the other hand plants lack such nervous system, but there are again some exceptions like the touch-me-not plant which closes the leaves when touched.

The cell structure of plants and animals. Most plants have rigid/hard cell walls and they also contain cellulose. But animal cells do not contain cellulose. While animals stop growing after they are mature, but plants grow in size and shape until they die.

Animals	Plants
1. Animals can move.	1. Plants cannot move
2. Animals have a nervous system which responds to stimuli	2. Plants lack a nervous system which responds to stimuli
3. Animal cells do not contain cellulose.	3. Plants have hard cell walls and have cellulose in them.
4. Growth stops when animal becomes mature.	4. Growth does not stop until the plant dies.

Table of differences  between plants and animals.

Now you know how the plants and animals differ each other, but a question arises which one of these two came first, plant or animal? We will discuss it in next part until then you can read our other blogs.

  

 

'What is an animal?' Animal World Part 1

Hello friends in now we are going to start a new series in which you will read about animals and it's name is 'Animal World'.

 Life is a very unique thing, and it is the only thing that makes our planet Earth different from other planets and without it our planet isn't so unique. The Earth has a diversity of living organisms from ants to whales, from rats to huge elephants, from a small plant to a huge tree there are a lot of organisms on the Earth.

Plants are stable and can not move from one place to another, while the animals can move to other places. The word animal comes from Latin word 'anima'. It means 'life' or 'breathe'. Animals and plants are play a very significant role in the ecosystem, while from the movement of animals we can easily differentiate between plants and animals, but there are other features of animals like- they eat food and they are capable of taking care of themselves.

But, the simplest animals are very similar to simplest plants. Sometimes it is difficult to differentiate between these two. 

So how can we easily differentiate between these two? We will discuss about this in it's next part, so stay tuned until then you can read our other articles.
