The ability to take in nutrients; this includes absorption, which is the ability to bring dissovled materials into the cell.
Ingestion
A tiny cellular structure that carries out a specific function necessary for the cell to survive.
Organelle
Large membrane-bound organelle used for storage of food, water, or waste.
Vacuole
A membrane that allows some molecules to pass through but does not alow other molecules to pass through.
Semipermeable membrane
The control center of the cell, contains DNA
Nucleus
The ability to release energy from the breakdown of food molecules.
Respiration
The semipermeable membrane between the cell contents and the cell's surroundings.
Plasma membrane
The organelle in animal cells responsible for hydrolysis reactions that break down proteins, carbohydrates and some lipids.
Lysosome
The random motion of molecules from an area of high concentration to an area of low concentration until its concentration becomes equal throughout the area.
Diffusion
A network of folded membranes studded with ribosomes that aid in protein synthesis.
RER
The ability to maintain internal stability (also known as regulation).
Homeostasis
A jellylike fluid inside the cell in which the organelles are suspended.
Cytoplasm
Double membrane-bound organelles found in the cells of plants, algae, and some protozoa, generally involved in either the manufacture or storage of food.
Plastids
Movement of molecules through the plasma membrane aided by a process that requires energy input
Active Transport
An organelle of flattened, interconnected membrane sacs responsible for modifying and packaging proteins for transport.
Golgi Apparatus
The ability to release biosynthesized substances.
Secretion
The motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents.
Cytoplasmic Streaming
Double-membrane-bound organelles in which nutrients are converted to energy.
Mitochondria
The diffusion of water through a semipermeable membrane from an area of high water concentration to low water concentration.
Osmosis
A small membrane-bound sac that transports wast, food, or products of biosynthesis
Vesicle
The ability to remove nonsoluble, undigested waste from the cell.
Egestion
A cell that has no nucleus or other distinct membrane-bound organelles.
Prokaryotic cell
Plastids containing th egreen pigment, chlorophyll, used in photosyntesis.
Chloroplasts
A solution that has a high solute concentration (and so a low water concentration) relative to another solution.
Hypertonic Solution
An organelle made of microtubules that aids in cell reproduction
Centrioles
