CELLS

Cells store and use Energy

The energy that cells need comes originally from the sun

Chloroplasts in plant cells trap light energy from the sun and change it into chemical energy

The chemical energy is stored in bonds

Plant and Animal cells

Chemical energy is stored in bonds between atoms of carbon, hydrogen, and oxygen

Both plant and animal cells break down the molecules by breaking the bonds

Energy is released when the bonds are broken

Cells can either use the energy or store it The mitochondria in plant and animal cells

use oxygen to release the energy in chemical bonds

ATP

Cells store chemical energy In ATP molecules

When a cell needs energy, the ATP is broken down

Cells store and use information

The nucleus of plant and animal cells is the control center of the nucleus

The nucleus contains DNA and RNA. DNA has the instructions, or the code, for

the entire cell DNA and RNA work together to make

proteins DNA in the cell’s nucleus determines

what kind of cell it is.

Cell division

When a cell divides and becomes two cells, information needs to be passed on to the new cell

This means that the DNA doubles when a cell divides

A new cell contains the needed information to carry out all of the cell’s activities
