Cell History & Theory
This English scientist built a microscope and discovered cells while examining cork tissue.
Who was Robert Hooke?
This substance makes up the majority of a cell's volume and is essential for chemical reactions.
What is water?
The flexible outer covering that protects the inside of every cell from the outside environment.
What is the cell membrane?
This organelle directs all cell activities and stores genetic information in eukaryotic cells.
What is the nucleus?
Simple cells that lack a nucleus and membrane-bound organelles.
What are prokaryotic cells?
The statement that "all living things are made of one or more cells" is part of this scientific framework.
What is the Cell Theory?
DNA and RNA belong to this group of macromolecules that store genetic information.
What are nucleic acids?
The fluid inside a cell that contains salts and other molecules.
What is the cell wall?
Plant cells use light energy to make food inside this organelle.
What is a chloroplast?
Complex cells that contain a nucleus, such as plant and animal cells.
What are eukaryotic cells?
Complete this part of the Cell Theory: "The cell is the basic unit of ______".
What is life?
These macromolecules store energy, make up cell membranes, and do not dissolve in water.
What are lipids?
The rigid structure found outside the cell membrane that provides support in plant cells.
What is the cell wall?
This organelle prepares and packages proteins into tiny vesicles for transport.
What is the Golgi Apparatus?
Two organelles/structures found in plant cells that are NOT found in animal cells
What are cell walls and chloroplasts?
According to Cell Theory, all new cells come from these.
What are pre-existing cells?
Sugars and starches are examples of this macromolecule used for quick energy
What are carbohydrates?
The network of protein threads inside a cell that provides frame, shape, and movement.
What is the cytoskeleton?
This web-like organelle helps produce proteins and lipids and moves materials inside the cell.
What is the Endoplasmic Reticulum (ER)?
This cell type processes energy in both chloroplasts AND mitochondria.
What is a plant cell?
True or False: Robert Hooke's discovery proved that all non-living things are made of cells.
What is False? (Cells are the basic unit of living organisms)
These macromolecules are made of amino acid chains and help with structural support and transport.
What are proteins?
General term for any specialized structure within a cell that performs a specific function.
What is the nucleus?
Cellular respiration occurs here to process energy in both plant and animal cells
What is the mitochondria?
Bacteria are examples of this general type of cell.
What are prokaryotes / prokaryotic cells?
