Terms in this set (37)
Control center of the cell, site where transcription occurs
A part of the cell containing DNA and RNA and responsible for growth and reproduction
Three regions of the nucleus
nuclear membrane, nucleolus, chromatin
Double membrane perforated with pores that control the flow of materials in and out of the nucleus.
Found inside the nucleus and produces ribosomes
Clusters of DNA, RNA, and proteins in the nucleus of a cell
present when the cell is not dividing and is scattered throughout the nucleus
plasma membrane (cell membrane)
Flexible, selectively permeable (having pores or openings) boundary that helps control what enters and leave the cell.
a microscopic membrane of lipids and proteins that forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in and out of the cytoplasm.
hydrophilic head, hydrophobic tail
also contains proteins, cholesterol, and glycoproteins
anchoring junction that prevents cells from being pulled apart
tight junctions and gap junctions
tight junction: binds cells to leak proof sheet
gap junction: allows communcation between cells
A jellylike fluid inside the cell in which the organelles are suspended
the portion of the cell outside the nucleus, site of most cellular activity
cytosol, organelles, and inclusions
The semifluid portion of the cytoplasm.
like tiny organs within cells.
Chemical substances such as stored nutrients or cell products
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
non membrane bounded organelles responsible for protein synthesis
Ribosomes are found where?
in the cytoplasm and on the rough endoplasmic reticulum
A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.
That portion of the endoplasmic reticulum studded with ribosomes, makes proteins
That portion of the endoplasmic reticulum that is free of ribosomes, makes lipids, carbs and steroid and detoxification of drugs
stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
golgi apparatus produce
secretory vesicles, cell membrane components, lysosomes
An organelle containing digestive enzymes
Uses chemicals to break down food and worn out cell parts
lysosomes are packaged by
the Golgi apparatus
Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals
Break down fatty acids and produce hydrogen peroxide
Peroxisomes replicate by
A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement
elements of cytoskeleton
microtubules(smallest), microfilaments(largest), intermediate filaments
a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
