Cells Flashcards
Cellular ropes made of repeating units of the protein actin
Microfiliament
Internal framework that anchors organelles, gives shape
Cytoskeleton
Hollow tubes for transport, movement. Made of actin and Tubulidentata proteins
Microtuble
Vesicles pinch off these structures, proteins modified and packaged here
Golgi body
Cellular stomach
Lysosomes
Selectively permiable doorman
Cell membrane
The most important plastid, turns co2 h2o into sun
Chloroplast
Membrane bound spheres that store water and dissolve materials , membrane around called tonoplast
Vacuoles
Site of rRNA production in nucleus
Nucleolus
Rod like structures that package the DNA into neat discrete unit, plays role in cell division
Chromosomes
Used for movement and to move material past cell beat back and forth like oars
Cilia
Site of lipid synthesis
Smooth er
Appearance due to being peppered with ribosomes , this membrane network receives just synthesized protein and may modify
Rough er
The brain of the cell
Nucleus
Organelle has double membrane and converts to glucose an o2 to produce energy in the form of ATP
Microchondria
Enclose plant cells, strong cellulose fibres give ridgeity
Cell wall
Small organelles I. Plants that contain pigment or starch
Plastids
Small membranous spheres that transport materials out of cell via exocytosis and into cell via endocoytosis
Vesicle
Made of RNA and protein these small numerous organelles are the site of protein synthesis
Ribosomes
Twin barrel like structures in animals that play a role in cell division , 9-triplet arangment of microtubles
Centriole
Whip like structures used for movement in unicellular organisms have 9+2 arrangement of microtubles
Flagella
Centrioles
9+0 pattern of microtubles
Animal cells only
Give rise to basal bodies
Microtubles
Made up of thirteen rows of Tubulin proteins
Arranged in hollow tube
Moves materials in cell
Cilia
Cell movement using ATP
9+2 arrangement of microtubles
Flagella
9+2 arrangement of microtubles
Cell movement using ATP
Ribosomes
Consist of rRNA and protein
Made of two units
Site for protein synthesis
What are the three membranes with double membranes
Microcondria, nucleus
Endotosis
Moves things into cell via membranous vesicles
Exotosis
Move things out of cell via membranous vesicles
Folded layers of membrane which act ad transport corridors through the cytoplasm of the cell
Endoplasmic reticulum
Names of the two subunits of ribosomes
Small and large
A small vacuole often secreted by Golgi apparatus
Vesicles
Folds of the Microcondria inner member where the cellular respiration reaction occurs
Cristae
These chemicals are a major component of the cell membrane
Phospholipid
Organelle responsible for protein synthesis
Ribosomes
Organelle which conducts photosynthesis
Chloroplast
Cells which have a membrane bound nucleus
Eukaryotic
The middle part of the cell membrane is called _______ because it is water fearin
Hydrophobic
A structure found inside of a cell which carries out a specific function
Organelle
The centre area of a mitochondrion
Matrix
Proteins that associate with DNA to form chromosome
Histones
