How do we classify something as living?

Living things…

1. Have a need for energy(from chemicals, sunlight, other animals, etc.)

2. Respond to their environment (to survive)

3. Have the ability to reproduce= pass genetic info

(asexual or sexual)

4. Are made up of one or more cells

Cell Theory3 basic components:1. All organisms are made of

cell(s).

2. All existing cells are produced by other living cells.

3. The cell is the most basic unit of life.

2 Types of Cells1. Prokaryotes= No nucleus

(“before” nucleus)◦Example = Bacteria

2. Eukaryotes= Nucleus (“true” nucleus)All other Kingdoms:◦Fungi ◦Plants◦Protists◦*Animals

Eukaryotic cells have many organelles- Structures that perform specific functions.

*plasma membrane, cytoplasm, nucleus

(Kingdom Fungi)(Kingdom Plantae)(Kingdom Protista)(Kingdom

Animalia)

Cell LocomotionCilia = “eyelashes”Flagella = “small whips”*Locomotion needed to find a food

source or escape predators/harsh conditions.
