Cell Structures
The outer boundary of the cell that controls movement in and out.
What is the plasma membrane?
Movement of molecules from high to low concentration.
What is diffusion?
Division of the nucleus resulting in two identical daughter cells.
What is mitosis?
Deoxyribonucleic acid, the molecule carrying genetic information.
What is DNA?
The process of making a protein from mRNA.
What is translation?
Organelle that contains DNA and directs cellular activities.
What is the nucleus?
Diffusion of water across a selectively permeable membrane.
What is osmosis?
Division of the cytoplasm at the end of mitosis.
What is cytokinesis?
Ribonucleic acid, a nucleic acid involved in protein synthesis.
What is RNA?
Proteins that catalyze chemical reactions.
What are enzymes?
Organelles that synthesize proteins.
What are ribosomes?
Movement of substances against their gradient using energy (ATP).
What is active transport?
What are the phases of mitosis in order?
Prophase, Metaphase, Anaphase, Telophase.
Building blocks of nucleic acids, consisting of sugar, phosphate, and base.
What are nucleotides?
Programmed cell death.
What is apoptosis?
he “powerhouse of the cell.”
What is the mitochondrion often called?
Passive transport that uses carrier proteins or channels.
What is facilitated diffusion?
The ordered sequence of events for cell growth and division.
What is the cell cycle?
Adenosine triphosphate, the cell’s main energy currency.
What is ATP?
The process of expelling material from a cell by vesicles fusing with the membrane.
What is exocytosis?
A network of protein fibers that supports cell shape and aids movement.
What is the cytoskeleton?
The process of a cell engulfing material into vesicles.
What is endocytosis?
The phase of the cell cycle where the cell grows and replicates DNA before division.
What is interphase?
The process of making RNA from DNA.
What is transcription?
The process by which cells use oxygen to produce ATP from glucose.
What is cellular respiration?
