Term
"Free" Ribosomes
Definition
Makes proteins that remain inside the cell.
Term
Cell or Plasma Membrane
Definition
Separates the cell's contents from the outside like a gate and moves substances into and out of the cell.
Term
Nucleus
Definition
Membrane bound and houses the cell's DNA.  Control center of the cell.
Term
Smooth Endoplasmic Reticulum (SER)
Definition
Makes lipids/detoxifies alcohol, no ribosomes
Term
Golgi apparatus
Definition
Sorts and packages proteins, post office of the cell
Term
Mitochondria
Definition
Releases the stored energy in food by converting glucose into ATP through cell respiration, powerhouse of the cell
Term
Cytoplasm
Definition
Area or space inside the cell, fluid of the cell.
Term
Lysosomes
Definition
Contains enzymes that cause the rapid break down of biomolecules/old cell parts, garbage can of the cell
Term
Rough endoplasmic reticulum (RER)
Definition
Makes proteins that leave/"E"xit the cell
Term
Chromosomes/DNA
Definition
Genetic hereditary material found in the nucleus
Term
Food vacuole
Definition
Stores food for the cell
Term
Cell wall
Definition
Made of cellulose and proteins/gives plant and bacteria cells extra support
Term
Chloroplast
Definition
Green/the site of photosynthesis in plant cells
Term
Central vacuole
Definition
Contains water, waste, and pigments in a plant cell
Term
Flagella
Definition
Used in locomotion/whip like action for bacteria and animal cells
Term
Vesicle
Definition
Transports substances (proteins and lipids) from the RER and SER to the Golgi apparatus
Term
_______ -->Tissues-->organs-->organ systems-->Body
Definition
cells
Term
What are made up of cells?
Definition
All living things.
Term
Where do all cells come from?
Definition
Pre-existing Cells
Term
What was the first kind of cell?
Definition
Prokaryote
Term
The cells that are move advanced; evolved later
Definition
Eukaryotes
Term
What structures do all cells have?
Definition
ribosomes, DNA, cytoplasm, and cell membranes
Term
What organelles do plants have that animals don't have?
Definition
cell wall, central vacuole, chloroplasts
Term
What type of cell are bacteria?
Definition
Prokaryotic cells
Term
What type of organisms have eukaryotic cells?
Definition
plants, animals, fungi, protozoa(protists)
Term
What is the endosymbiont theory?
Definition
An explanation about how some prokaryotes began to live inside of other prokaryotes and that led to the more advanced eukaryotic cells.
Term
What cell structure do bacteria and plants have that animals don't have?
Definition
cell walls
Term
Which cells have true nuclei and membrane bound organelles?
Definition
Eurkaryotic cells
Term
What is the Cell Theory?
Definition
1. All cells come from preexisting cells. 2. Cells are the basic structure and function of all organisms. 3. All living things are made of cells
Term
When did the first prokaryotic cells evolve?
Definition
3.6 billion years ago

Definition
ribosome
Term
cytoskeleton
Definition
The cell's “skeleton.” It defines the shape of the animal cell and determines its rigidity. It helps anchor organelles and is responsible for cell motility(movement).
Term
nuclear pores
Definition
allows substances in and out of the nucleus
Term
nucleoplasm
Definition
fluid or space inside the nucleus
Term
nucleolus
Definition
"little" nucleus, makes ribosomes
Term
What biomolecules make up cells?
Definition
lipids, proteins, carbohydrates, and nucleic acids
Term
What biomolecules make up the cell membrane?
Definition
phospholipids, carbohydrates, and proteins
