Plant cell and Animal cell

Both plant and animals are made up of cells. Both cells are eukaryotic in nature, having a well defined membrane – bound nucleus.

Plant cell and Animal cell

Both plant and animals are made up of cells. Both cells are eukaryotic in nature, having a well defined membrane – bound nucleus.

1. Plant cell

* It is usually larger in size. It is hard in nature.

* Plant cell have a cell wall in addition to their cell membrane.

* Plant cell have chloroplast which contain chlorophyll

* Plant cells have large vacuoles. Centrioles are absent.

2. Animal cell

* Animal cells are generally smaller than plant cells. It is not so hard as plant cell.

* A cell wall is absent.

* Chloroplast is usually absent.

* An animal cell may have many small vacuoles.

* Centrioles are found in animal cells.

3 Dimension - cell structure

1. How does a cell look like?

2. What is its shape and size?

The above cell has a three dimensional view. We can see the three sides of the cell structure. You can also view the size, shape and location on the organelles of the cell also.

3-D view is appealing because it is more like reality.

In 3-D, We can see the entire view of the cell. It exposes the accurate size and shape and shows the correct location of the cell organelles.

Activity 3:

Aim:

To rectify the variation between 2-D shape and 3-D shape.

Material required:

Polythene bag, water, marble ball (golli gundu)

Procedure:

Take a polythene bag with water. Put a marble ball into the polythene bag. Then draw a picture in your note book about this task.

If you draw a picture in round shape.

It will be called 2-Dimenstional picture.

If you draw a picture in spherical shape it is called 3-dimenstional.

Result:

Now you understand your misconceptions. So the animal cells are spherical in shape and structure, not in a round shape.
