cell organelles general biology

	a part of the cell containing DNA and RNA and responsible for growth and reproduction
	A highly-porous membrane that separates the nucleus from the cytoplasm
	A small hole in the nuclear envelope through which substances pass between the nucleus and the cytoplasm
	small, dense region within most nuclei in which the assembly of proteins begins
	a cell organelle composed of RNA and protein; the site of protein synthesis
	System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm
	A network of membranes inside eukarytoic cells invovled in lipid synthesis (steroid in gonads), detoxification (in liver cells), and/or Ca2+ storage (muscle cells).
	Organelle that modifies, sorts, and packages proteins from the endoplasmic reticulum and send proteins to their final destination
	vesicles that bud from the Golgi apparatus and that contain digestive enzymes
	Powerhouse of the cell, organelle that is the site of ATP (energy) production
	Organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis
	a membrane-bound sac within the cytoplasm that is filled with water and dissolved substances. stores metabolic wastes and gives a plant cell support by means of turgor pressure
	One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope; play a role in cell division.
	strong supporting layer around the cell membrane in plants, algae, and some bacteria
	thin, flexible barrier around a cell; regulates what enters and leaves the cell
	newly discovered organelle that is thought to play a role in the transport of molecules (such as mRNA) from the nucleus to the cytoplasm.
	a jellylike fluid inside the cell in which the organelles are suspended
	Threadlike strands of DNA and protein in a cell nucleus that carry the code for the cell characteristics of an organism.
	saclike structures that store materials such as water, salts, proteins, and carbohydrates
	The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles; includes the nuclear membrane, smooth and rough endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.
	A meshwork of fine fibers in the cytoplasm of a eukaryotic cell; includes microfilaments, intermediate filaments, and microtubules
	The thinnest of the three main kinds of protein fibers making up the cytoskeleton of a eukaryotic cell; a solid, helical rod composed of the globular protein actin
	An intermediate-sized protein fiber that is one of the three main kinds of fibers making up the cytoskeleton of eukaryotic cells. Intermediate filaments are ropelike, made of fibrous proteins.
	The thickest of the three main kinds of fibers making up the cytoskeleton of a eukaryotic cell; a straight, hollow tube made of globular proteins called tubulins. These form the basis of the structure and movement of cilia and flagella.
	A type of cell lacking a membrane-enclosed nucleus and other membrane-enclosed organelles; found only in the domains Bacteria and Archaea.
	A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells.
	This says that all living things are made of cells, that cells are the basic unit of structure and function and that cells only come from other cells.
