Chapter 3 Flashcards
Semi-fluid portion of the cytoplasm
Cytosol
Control center
Nucleus
Intracellular structures with specific functions
Organelles
Responsible for forming the spindle during mitosis
Centrosome
Modifies, sorts, packages and delivered proteins and lipids
Golgi complex
Organelles that destroy bacteria and recycle worn out cell parts
Lysosomes
Non membranous chemical substances that are produced and used by cells
Inclusions
Located inside the nucleus and helps assemble ribosomes
Nucleolus
Cellular respiration occurs here
Mitochondria
Protein synthesis occurs here
Ribosomes
Passive transport depends on this type of energy to move materials
Kinetic
When a solution reaches equilibrium, an _____ number of molecules move in and out of a cell
Equal
Mechanisms that move substances across a cell membrane requiring energy
Active transport
The infolding of a cells membrane around a liquid droplet to bring it into the cell
Pinocytosis
In passive transport, net movement of substances is (up, down) their concentration gradient
Down
Movement of any substances from high concentration to low concentration wether or not a membrane is involved
Simple diffusion
Movement of a substance from a low concentration to a high concentration
Active transport
In exocytosis, these structures unite with the cell membrane and release their contents to the outside of the cell
Vesicles
Phagocytosis is process by which _______ are taken through a cell membrane
Insoluble solids
The word gradient means
Difference
The majority of the plasma membrane is composed of this type of molecule
Phospholipids
Cellular contents located between the plasma membrane and the nuclear membrane
Cytoplasm
Name the two types of ER
Rough, smooth
What structures are attached to the rough ER
Ribosomes
