Cell Theory

What does a cell membrane do for an animal cell?
It is a layer of the cell that acts as a barrier, letting certain substances in and out of the cell. This layer surrounds the cytoplasm.
100
How does a vacuole help an animal cell?
Vacuoles don't actually need to be in an animal cell, but when they are, they store waste and other extra things inside a cell, like water.
100
Does an animal cell have a cell wall?
No, an animal cell only has a cell membrane.
100
Does the cell theory include anything about microscopes leading to the discovery of cells?
No, the cell theory does not state this.
200
What is the cytoplasm of a cell?
A jelly-like substance inside the cell that holds all of the organelles within it.
200
What is the job of a lysosome in a cell?
This organelle has digestive enzymes that help the organelle break down waste within the cell. An example of waste is a worn-out organelle.
200
Do animal cells go through photosynthesis?
No, because animal cells do not consist of chloroplasts.
200
True or false?
The cell theory states that cells are the basic building blocks of all living things.
This is true. The cell theory does contain this.
300
What is the nucleus' job in an animal cell?
The nucleus is the control center of the cell. It carries DNA and contains a nucleolus along with chromatin. The nucleus looks over the cell's activities and it helps manage cell division.
300
How does a cell benefit from a mitochondrion?
The mitochondrion is the powerhouse of the cell. It provides and stores energy in the cell.
300
What is osmosis?
Osmosis occurs when some molecules pass through a semi-permeable membrane.
300
Who proposed the cell theory?
Matthias Schleiden, Theodor Schwann, and Rudolf Virchow all contributed to the cell theory.
400
How is a cell helped by the cytoskeleton?
The cytoskeleton gives shape to the animal cell. It also allows movement within the cell, and it helps cell division.
400
What is the job of a Golgi complex?
The Golgi complex processes things like lipids and proteins within the cell.
400
Where is chromatin kept in a cell?
Chromatin is kept in the nucleus of a cell.
400
Do all cells come from existing cells?
Yes, they do. This is part of the cell theory.
500
What do ribosomes do and where can you find them?
Ribosomes provide protein to the cell. You can find them floating within the cytoplasm or attached to the endoplasmic reticulum.
500
How does a smooth endoplasmic reticulum help an animal cell?
The smooth endoplasmic reticulum synthesizes lipids like phospholipids.
500
What is the job of a rough endoplasmic reticulum?
Rough endoplasmic reticulums produce protein.
500
All living things have to have more than one cell according to the cell theory.
This is not true. The cell theory states that every living thing is composed of one or more cells. Therefore, living things can only have one cell.
