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.
