Cards in this deck (32)
- 1The gene containing control centerNucleus
- 2Bounding the nucleus is the __________nuclear membrane
- 3The membrane is _________Seletively permable
- 4A jellylike substance that encloses the membrane is ____________Nucleoi Plasma
- 5___1____Inside the nucleus and the site where __2__1. nucleus
2. ribosomes - 6The___1__ eventually migrate into the cytoplasm and serve as the site of ___2____1. ribosomes
2. protein sythesis - 7The gentic material __1__ has the instructures for building __2_ that builds cells>tissues>ograns1. DNA
2. proteins - 8Chromatina loose network of threads formed formed by the combination of DNA and proteins that are scatted throughout the nucleus during interphrase ( cell not divided)
- 9Chromosomesis the tightly coiled version of chromosomes that occurs during metosis
- 10The Plasma/Cell Membranea transport barrier that contains the cell's contents and seprates them from the surrounding env.
- 11Microvillitiny finger-like projection that greatly increase the cell' surface for absortion
- 12Tight junctionBonds two cells together into leak proof sheets that prevent substance from pressing through the extracellular space
(Ex. skin cells) - 13DesmosomesHold cells together and prevent the cells from being subjected to mechial cell from being pulled apart.
- 14Gap junctionsallow direct passage of molecules such as nutrients from one cell to another
- 15Cytoplasmconsists of the cell material outside of the nucleus and inside the cell membrane
- 16cytosolis the semi-transparent fluid which suspends the elements inside the cell
- 17inclusionsare stored nutriets such as fat and pigment such as melaton seen in the skin and hair cells
- 18organellesthe metabolic machinery of a cell
- 19__________________ is the powerhouse of the cell and contains enzymes to breakdown food,Mitochondria
- 20_______1_______ from brokendown food escapes as heat or is captured to form __2__ molecules1. Energy
2. ATP - 21____ provides the energy a cell needs for its many activities1. ATP
- 22Ribosomesare the actual sites of protein sythesis in the cell
- 23Endoplastic reticulum (ER)a system of fluid filled canals that coil and twist through the cytoplasm
- 24The ER serves as a mini circulatory system for the cell, b/c it provides a _______ for carrying sub. from one part of the cell to another.natural channels
- 25Rough ERcontain protein producing ribosomes and the amount of rough ER a cell to another.
- 26Ribosomesare the amount of protein a cell makes (muscle cell = )
- 27Smooth ERnetwork of channels, but and breaks down cholestrol and detoxifies drugs.(liver)
- 28Golgi Apparastusa stack of flat membranes sacs that function in modfying and packaging proteins ( from rough ER via vesicles)
- 29Lysosomescontain powerful enzymes that are capable of digesting worn cell, structures and foregin substances and are abundant in white blood cells
- 30Peroxisomesthe membranous sacs containing powerful oxolose enzymes that help to digest fat and to detoxify harmful or poisonous substances.
- 31Cytoskeletonelaborate network of _____
structures that extends throughout the ____ and deterimes a cell's ____ and ____ oter organelles - 32Centrioles
