Tissue is a group of something that works together to carry out a job for an organism. What is that something tissue is made out of?
Cells (of one kind)
Which type of cell makes up most multicellular organisms?
Eukaryotic
Which of the following is a method of transport that requires energy: osmosis, diffusion, meiosis, or endocytosis?

What are the three parts of the cell theory?
1. All living things are composed of one or more cells.
2. Cells are the basic unit of structure and function in living things.
3. All cells come from other cells.
What cell structures are found in plant cells but not animal cells?
Cell walls and chloroplasts
What is the difference between autotrophs and heterotrophs?
Autotrophs produce their own food, and heterotrophs must eat plants or other animals to get food.
What are the four steps of mitosis called, and why is the process of mitosis important?
1. prophase, metaphase, anaphase, and telophase
2. Mitosis ensures that the new cells produced will have the exact same DNA
