Cells in real life

Do the cells in our body all look like the pretty picture on the presentation? Of course not. Do all of our cells look the same? Of course not.

Watch this video to see some AMAZING pictures of cells that are in your body!



The picture below shows the level of organization within an organism.

The plant cell too?

A plant cell has all of the same major organelles as an animal cell, such as:

cell membrane
nucleus
cytoplasm
vacuole
lysosomes
ribosomes
golgi bodies
endoplasmic reticulum
mitochondria

BUT...a plant cell has two more parts that have extremely important functions.

cell wall - gives extra structure and protection to the plant cell

chloroplast - produces "food" for the cell through the process of photosynthesis

All these parts? In one tiny animal cell? That's AMAZING!

View the presentation below to see all of the AMAZING organelles that make up an animal cell and their functions.

The Result is....Cell Theory!

Thank you Theodor Schwann! Thank you Rudolf Virchow! Thank you Matthias Jakob Schleiden!

The work of these historical scientists was combined to create a theory of cells. There are 3 parts to the cell theory:

• All living things are composed of cells.
• Cells are the basic unit of structure and function in living things.
• All cells are produced from other cells.

The Amazing Discovery of Cells

Once upon a time, long, long ago there were many scientists that worked hours and hourse to discover the tiniest living part of an organism - the cell!
