Cells: structure and functions, chemistry of life

By Cindy Guzman

It's the smallest functional and structural unit of all living organisms.

​​Cell

makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies

Why are important?

A cell is the smallest functional and structural unit of all living organisms.

​

Must carry out all of its life functions.

Unicellular Organisms

​

​They're made up of more than one cell.

Multicellular Organisms

​

• All cells come from existing cells.

• The cell is the basic unit of all organisms.

• All organimis are mede up of one or more cells. ​

Some text here about the topic of discussion

• A cell membrane is made of phospholipid molecules.

​

• The tail of the phospholipid is made up of carbon and hydrogen atoms. ​

• lipids

• carbohydrates

• proteins

• nucleus acids​
