Organelles
Plant vs Animal cells
Characteristics of Living things
Organ Systems
100
Group of tissues that work together to form a specific body part
An organ
100
This organelle takes in sugars and produces energy for the cell
Mitochondria
100
Only plant cells have this protective organelle that gives it structure
Cell wall
100
Example of this is taking in oxygen and exhaling
Every living thing breathes
100
This organ system helps us breathe and take in oxygen
Respiratory System
200
This is the smallest building block in organisms
A cell
200
This is the control center of the cell and houses all the genetic material
Nucleus
200
This type of cell is square or rectangular in shape, looks like brick wall under microscope
Plant cell
200
Example of this is a dog having a litter of puppies
Every living thing reproduces.
200
This organ system contains the stomach and intestines
Digestive system

The jelly-like substance that fills the inside of a cell, surrounds and protects other organelles
Cytoplasm
300
which type of cells are these?
Animal Cells
300
Examples of this characteristic are a plant moving towards sun, dog drooling when seeing food
Every living thing reacts/responds to stimuli
300
This organ system involves the brain sending signals to other parts of the body
Nervous system
400
This is a group of cells that work together
Tissue
400
Separates inside from outside of cell; lets good in and bad stuff out
Cell membrane
400
This type of cell is more rounded or smooth shape, not attached to each other
Animal cell
400
Example of this is a girl growing 3 inches during middle school.
Every living thing grows and develops
400
This organ system helps the body get rid of waste
Excretory System
500
Many organ systems working together to form a whole
Organism
500
This is only in plant cells; helps plants produce food through photosynthesis
Chloroplast
500
Which type of cells are these?
Plant cells
500
Example of this is an eagle catching and eating a mouse
Every living thing gets and uses energy
500
This organ system works with the skeletal system to make our body move
Muscular system
