WHAT IS A CELL?

Cells are the basic unit of all living things. All cells need energy, get rid of waste and contain genetic material to make more cells. Some living things are made of only 1 cell (unicellular) and other organisms like humans are made of many cells working together (multicellular).

To better understand cells…

LET’S BREAK IT DOWN!

All living things are made of cells.

All living things are made of cells.

Cells can be seen with a light microscope which can magnify objects up to 1,000 times. Typically a microscope slide is prepared which creates a thin layer of cells and holds them in place. Dye is used to stain the cells, making them easier to see. Cells can range in size. For example, an amoeba is about 1 mm in length and the biggest ones can be seen without a microscope. A red blood cell is 100x smaller at 0.01 mm and a bacteria is 1000x smaller than an amoeba at about 0.001 mm.

Plant & Animal Cells Have Organelles.

Plant & Animal Cells Have Organelles.

Organelles are parts of a cell that help the cell to function and stay organized. The mitochondria, for example, is where sugars are used to produce energy. The vacuole is a membrane bound organelle that stores fluids. The cell membrane controls what comes in and out of a cell. Plant and animal cells need organelles in order to carry out their everyday functions.
