List the organelles and their function that plant cells have that animal cells do not
Bonus: List one that they share, but there is a major size difference between them and why
Chloroplasts: Turn sunlight into food
Cell wall: Provide structure and support
Bonus: Vacuole: storage facility, plants have 1 very large vacuole
List three examples of models...

A all living things are made of cells
B basic unit of life
C cells come from pre-existing cells
Place the following terms in order of least specific to most specific...
cell, organism, organ system, nucleus
nucleus, cell, organ system, organism
Which statement describes BOTH plant and animal cells...
A) Must consume food in the form of other organisms
B) Convert the sun's energy into sugars
C) Produce carbon dioxide as waste
D) Require mitochondria to produce useable waste
E) Use water and carbon dioxide to produce energy
F) Require oxygen to get energy from food
Animal: A,C
Plant: B,E
Both: D, F
As an animal cell takes the food eaten and turns it into energy, while breaking down the food, waste is created in the process. This waste is specifically carbon dioxide, what is the best reason to determine why the cell is doing this?
A) To be the biggest strongest cell in the body
B) To make more cells
C) To maintain homeostasis
D) To protect itself and other cells around it
C) To maintain homeostasis
It can show something too small/too large to see, provides a visual of something that may be hard to imagine.
Pretend you have dove to the deepest part of the ocean where no man has been before. You find a strange creature down in the deep, how can you determine if this creature is living?
A) The creature must breath oxygen
B) The creature must be able to move
C) The creature must be made of one or more cells
D) The creature must be able to reproduce
C) The creature must be made of one or more cells

List the organelles plant and animal cells share and their jobs
Mitochondria: Breaks food into energy
Vacuole: Stores water, waste, and food
Nucleus: Contains the DNA, command center
Cytoplasm: Jelly like holds other organelles in place
Cell Membrane: Gatekeeper, determines how much food, water, and waste can enter and leave the cell
Define hypothesis
Limited evidence, few observations, what theories and laws begin as
Write your own hypothesis in an if, then, because statement
If the grass in my backyard is dying, then we may be in a drought, because plants need water to survive and it rained in a while.
If a cell falls out of homeostasis what happens?
The cell may not function properly, you may become sick, after a long time the cell may die
