Cell Organelles and Their Functions

for Mrs. Ferranti's AP Bio class

	Boundary between intracellular and extracellular environment. Regulates entry and exit of substances
	a netlike array of protein filaments lining the inner surface of the nuclear envelope; it helps maintain the shape of the nucleus.
	combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus of a eukaryotic cell
	The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
	contains collections of enzymes that perform specialized tasks, including the synthesis of membrane lipids, and the detoxification of drugs. Is free of ribosomes.
	Organelle that modifies, sorts, and packages proteins from the endoplasmic reticulum and send proteins to their final destination
	a large membrane covered structure found in plant cells that serves as a storage container for water and other liquids
	organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use
	One of a family of closely related plant organelles, including chloroplasts, chromoplasts, and amyloplasts (leucoplasts).
	organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis
	A microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide..
	a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
	A solid rod of actin protein in the cytoplasm of almost all eukaryotic cells, making up part of the cytoskeleton and acting alone or with myosin to cause cell contraction.
	Open channels in the cell wall of a plant through which strands of cytosol connect from an adjacent cell.
	specialized junctions that hold adjacent cell together, consist of dense plate at point of adhesion plus extracellular cementing material
	small membrane sacs that specialize in moving products into, out of, and within a cell
	a thin membrane around the cytoplasm of a cell
	structures in the nuclear envelope that allow passage of certain materials between the cell nucleus and the cytoplasm
	The chemical substances located between connective tissue cells.
	small particle in the cell on which proteins are assembled; made of RNA and protein
	is a eukaryotic organelle that forms an interconnected network of tubules, vesicles, and cisternae within cells. Rough endoplasmic reticula synthesize proteins, studded with ribosomes.
	cell organelle filled with enzymes needed to break down fats and polysaccarides
	A membrane that encloses the central vacuole in a plant cell, separating the cytosol from the vacuolar contents, called cell sap; also known as the vacuolar membrane.
	An infolding of the inner membrane of a mitochondrion that houses the electron transport chain and the enzyme catalyzing the synthesis of ATP.
	One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope; play a role in cell division.
	A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
	The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
	straight, hollow tube of proteins that gives rigidity, shape, and organization to a cell.
	A component of the cytoskeleton that includes all filaments intermediate in size between microtubules and microfilaments.
	A type of intercellular junction in animal cells that prevents the leakage of material between cells.
	A type of intercellular junction in animals that allows the passage of materials between cells.
