Cells

All organelles are suspended in cytoplasm Mostly water with other substances the cell stored until needed can change from jelly to liquid

• All living things are made up of one or more cells and their products • Simplest unit that can carry out all life processes • Come from other cells not non living things

Simple, single celled No nucleus or other membrane bound organelles

Have a complex internal organization Has a nucleus

Semi permeable Flexible and double layered Supports the cell and allows some substances to enter while keeping others out

“Brain” Contains genetic info that controls all cell activities ( genetic info stored in chromosomes ) contains DNA (carries coded instructions)

Makes energy available for the cell Contains enzymes that help with cellular respiration

“Subway system” 3D network of branching tubes and pocket fluid filled tubes transport materials such as proteins through the cell

Collects and processes materials to o be removed from the cell Makes and secretes mucus

Single layer of membrane enclosing fluid Functions include removing unwanted substances from the cell and maintaining internal fluid pressure (turgor) within the cell

Provides support for the cell and protection from physical injuries

Gives green colour to plants and helps with photosynthesis

When full of water, turgor pressure keeps the cells plump and keeps stems and leaves firm
