Cards

Term
Cell membrane
Definition
A phospholipid layer that covers a cell's surface and acts like a barrier between the inside of the cell and the cell's environment/allows nutrients in and waste products out
Term
Cell wall
Definition
A structure made from cellulose that surrounds the cell membrane of some cells and provides strength and support to the cell
Term
Chloroplast
Definition
Found in plants and algae/makes food using the energy of the sun
Term
Chlorophyll
Definition
Chemical found in chloroplasts that traps light energy/makes chloroplasts green
Term
DNA
Definition
Heredity material found in the nucleus of the cell
Term
Endoplasmic reticulum
Definition
Looks like flattened sacks stacked side by side or like cloth folded back and forth/transports material from the nucleus to other parts of the cell
Term
Golgi complex (aka - Golgi apparatus, Golgi body)
Definition
Processes and transports material received from the endoplasmic reticulum out of the cell by using small compartments called vesicles
Term
Lysosomes
Definition
Digests food particles, wastes, old cell parts, and other foreign invaders
Term
Mitochondria
Definition
Breaks down food particles to make ATP (energy)/bean-shaped organelle that is surrounded by two membranes
Term
Nucleus
Definition
The most visible organelle when looking through a microscope/contains the cell's DNA and is the control center of the cell
Term
Ribosome
Definition
The site where amino acids are hooked together to make proteins/the only organelle in eukaryotic cells that is not covered my a membrane/smallest most abundant organelle
Term
Vacuole
Definition
Membrane-covered chamber that stores food, water, and other materials/the pigment in vacuoles is what gives some plants their color/makes celery crispy
Term
Multicellular
Definition
Organisms that are composed of more than one cell
Term
Unicellular
Definition
Organisms that are composed of only one cell
Term
Organelles
Definition
Specialized structures which carry out the cell's life processes
Term
Cytoplasm
Definition
Jelly-like fluid inside if the cel
Term
Nucleolus
Definition
Stores the materials that will be used later to make ribosomes in the cytoplasm
Term
Prokaryote
Definition
Organism without a nucleus
Term
Prokaryote
Definition
Organism with no membrane-covered organelles
Term
Prokaryote
Definition
Organism with circular DNA
Term
Prokaryote
Definition
Bacteria
Term
Eukaryote
Definition
Organism with a nucleus
Term
Eukaryote
Definition
Organism with membrane-covered organelles
Term
Eukaryote
Definition
Organism with linear DNA
Term
Eukaryote
Definition
All other cells except bacteria
