This organelle is in both plants and animals. It is a barrier between the cell and the environment. It controls what goes in and out of a cell.
cell wall
cell membrane
cell organelles
mitochondria
This cell part is in ALL cells. It is the gel-like substance that provides cell shape.

Chromosomes
Cytoplasm
Mitochondria
This structure is only in plant cells. It is outside of the cell membrane and adds more support/structure to the plant.
Cell membrane
Cell Nucleus
Cell Wall
Endoplasmic Reticulum
What is the main function of the cell membrane?
Digestion
Storage
Protecitve Barrier
Roadway for the cell

What is the difference between a scientific law and a scientific theory?
A law usually uses math to describe phenomena but does not explain why they occur. A theory explains why phenomena occur using evidence.
A law has not been fully tested yet. A theory describes phenomena but does not explain why they occur.
Laws were discovered long ago, theories are recent discoveries.
A law has no evidence to back it up. A theory is just a guess.
Which three statements are part of the cell theory?
All living things are composed of cells.
The basic components of life consist of a nucleus and a cell membrane.
Cells are the smallest unit of living things that can perform the processes necessary for life.
Atoms are composed of cells.
Living cells come only from other living cells.
Advancements in microscope technology led to discoveries that helped form the cell theory. Which characteristic of "the nature of science" was demonstrated in the development of the cell theory?
Science is a competition for fame.
Science is an unchanging field.
Science is completed alone (in isolation).
Science is based on evidence.
An amoeba is a unicellular organism, while a cat is a multicellular organism. Which statement is true about both of these organisms?
They both have many cells.
They both have specialized cells
They both have a way to take in and release gases
They both have a hierarchy of cellular organization.
Multicellular organisms have a hierarchy of cellular organization. Cells perform different functions to carry out life processes within the hierarchy. What is the hierarchy of cellular organization from least complex to most complex?
Organ system, organ, tissue, cell
Organ, tissue, cell, organ system
Cell, organ system, organ, tissue
