Term
Cell Membrane
Definition
Controls what moves in and out of the cell and gives the cell shape.
Term
Nucleus
Definition
Control center, contains heredity material.
Term
Nuclear Membrane
Definition
Surrounds the nucleus and separates it from the rest of the cell.
Term
Nucleolus
Definition
Dark shadowy spot in the nucleus that makes ribosomes.
Term
Chromosome
Definition
Located in the nucleus and carries DNA
Term
Cytoplasm
Definition
Clear jelly where chemical reactions occur here due to high water content.
Term
Ribosome
Definition
Found in the cytoplasm, puts amino acids to make proteins
Term
Mitochondria
Definition
Makes energy from respiration, powerhouse of the cell.
Term
Vacuole
Definition
Membrane bound package that stores food, water, and minerals.
Term
Lysosome
Definition
Vacuole with digestive enzymes that speed up food breakdown. (not in plant cells)
Term
Rough Endo Reticulum
Definition
Has ribosomes on the outside, makes membranes, and makes secretory proteins.
Term
Smooth Endo Reticulum
Definition
System of tubes that runs through the cell, makes lipids and stores calcium.
Term
Golgi Body
Definition
Receives and modifies substances made in the ER, packages products/waste to leave the cell.
Term
Chloroplast
Definition
Contains chlorophyll, and is the location for photosynthesis.
Term
Cell Wall
Definition
Thick outer covering outside the cell membrane in plant cells.
Term
Energy

The energy actually doing work.
Term
Chemical energy
Definition
Potential energy of molecules that does the work of cells.
Term
Potential energy
Definition
stored energy
Term
Endergonic reactions
Definition
Require an input of energy.
Products have more energy than reactants.
Term
Exergonic reactions
Definition
releases energy, reactants have more energy than products.
