Flashcards in Chapter 4 - Cells Deck (38):
Theory that all organisms consist of one or more cells, which are the basic unit of life; all cells come from division of pre-existing cells and all cells pass hereditary material to offspring
Semifluid substance enclosed by a cell's plasma membrane.
Organelle with two membranes that holds a eukaryotic cell's DNA
Structure that carries a specialized metabolic function inside a cell
A cell's outermost membrane - semi-permeable
A relationship in which the volume of an object increases with the cube of the diameter, and the surface area increases with the square
Organelle of protein synthesis
Small circle of DNA in some bacteria and archea
Protein filament that protects from the surface of some bacteria and archea
Region of cytoplasm where DNA is concentrated inside a bacterium or achaeon
Long, slender cellular structure used for motility
Semirigid but permeable structure that surrounds the plasma membrane of some cells
Community of microorganisms living within a shared mass of slime.
Protects and controls access to DNA and has membrane
Routing, modifying mew polypeptide chains, synthesizing lipids and has membrane
Modifying new polypeptide chains and lipids, sorting and shipping proteins and lipids. Membrane
Small, membrane enclosed organelle that's involved in Transporting, sorting, or digesting substances in a cell
Transporting, storing, or digesting substances in a cell.
Make ATP to break down glucose
Photosynthesis in plants, some protists
Enzyme filled vesicle that functions in Intracellular digestion
Enzyme filled vesicle that breaks down amino acids, fatty acids, and toxic substances
Fluid filled organelle that isolates or disposes of waste, debris, or toxic materials.
Assembling polypeptide chains. NO MEMBRANE
Anchor for cytoskeleton. NO MEMBRANE
Contributes to cell shape, internal organization, movement. Microtubules, microfilaments, intermediate filaments
Modifies proteins made by ribosomes attached to it
Makes lipids, breaks down carbohydrates and fats, inactivates toxins
Collective term for DNA molecules together with their associated proteins.
A structure that consists of DNA and associated proteins; carries part or all of the cell's genetic information
A double membrane that constitutes the outer boundary of the nucleus. Pores in the membrane control which substances can cross.
In a cell nucleus, a dense, irregular shaped region where ribosomal subunits are assembled
Viscous fluid enclosed by the nuclear envelope
Fluid-filled vesicle in many plant cells
Series of interacting organelles(ER, golgi, vesicles)between nucleus and plasma membrane; produces lipids, proteins.
Organelle of photosynthesis in the cells of plants and many protists
Organelle thar produces ATP by aerobic respiration in eukaryotes
