What are they

What are cells

Cells are what makes everything on Earth. There are some some smaller pieces to cells called proteins and organelles. There are also larger pieces to cells called tissues and systems. Cells are what contain the essential things to keep you alive and everything else on earth as well. They are found on every living organism in the whole world. The picture below is an animal cell, inside it the components that are used to keep them alive.

How many types of cells are there

There are many types of cells in the world. The two main ones are plant like cells and animal like cells. Plant cells are easier to identify because they make a cell wall which is made of cellulose. Plants have a wall, animals do not. Plants have organelles which contain chloroplast which is what makes them green.

All cells are different. Humans have thousands of different cells in our body. Some are used to carry oxygen through our body. Some are used to fight bacteria in our systems. They are used for many things.

Cell theory

What is cell theory

Cell theory is the principle that describes the fundamental unit of all living cells.

The three rules of cell theory

1. All organisms are made of on or more cells

2. All cells are the unit of structure and function of living things

3. All cells are made from other existing cells


What are microscopes

The definition of a microscope is - An optical instrument with one or more lenses magnified to see things too small for the naked eye to see.

Some of the different types of microscopes are electronic microscopes, simple microscopes, compound microscopes, dissection microscopes etc.

They use these different microscopes to find things too small for the naked eye but they can be used for many other things like particles different parts of organisms too small for the naked eye to see. Scientists use microscopes to generally see cells much too small for the naked eye to see.

Mount slides

What is the difference of a wet mount slide and a dry mount slide

Wet mount slides are used to contain the organelles that get squashed by the mount.

The procedure for doing that is:

Place the cell or specimen on a microsope slide with a drop of water on it. Gently place the thin glass cover slip onto it. The best way to do that is to place the edge of the cover slip first and lower it onto the specimen. Then use some filter paper to soak up the excess water.

Dry mount slides aren't as effective because the organelles will get squashed and they will go everywhere. That is is why you should use a wet mount slide instead of a dry mount slides.
