Cell Basics
This is the smallest unit of life.
What is a cell?
This model describes the dynamic structure of the plasma membrane.
What is the fluid mosaic model?
This is the diffusion of water across a selectively permeable membrane.
What is osmosis?
This is the site of ATP production.
What is the mitochondrion?
This phase of the cell cycle is where the cell grows and replicates DNA.
What is interphase?
This cell part contains 70% water and surrounds organelles.
What is the cytoplasm?
These proteins are embedded in the membrane and may act as channels or carriers.
What are integral proteins?
This kind of transport requires no energy and moves substances down a gradient.
What is passive transport?
These are the two types of endoplasmic reticulum.
What are rough and smooth ER?
The stage of mitosis where chromosomes line up at the center.
What is metaphase?
The theory that states all organisms are made of one or more cells.
What is cell theory?
This type of junction prevents substances from passing between cells.
What is a tight junction?
This pump moves sodium out and potassium into the cell using ATP.
What is the Na⁺/K⁺ ATPase pump?
This organelle packages and ships proteins and lipids.
What is the Golgi apparatus?
This molecule carries the genetic code from DNA to the ribosome.
What is mRNA?
This fluid surrounds cells and includes interstitial and intravascular fluids.
What is extracellular fluid (ECF)?
This sugar-rich coating helps with cell recognition and adhesion.
What is the glycocalyx?
A red blood cell will swell and burst in this type of solution.
What is a hypotonic solution?
This structure breaks down hydrogen peroxide.
What is catalase (in peroxisomes)?
This form of cell death is orderly and programmed.
What is apoptosis?
This part of the cell contains genetic information and is surrounded by a double membrane.
What is the nucleus?
These are the three types of specialized cell junctions.
What are tight junctions, desmosomes, and gap junctions?
This form of vesicular transport brings fluids into the cell.
What is pinocytosis?
These extensions help move substances across the surface of the cell.
What are cilia?
These RNA molecules bring amino acids to the ribosome during translation.
What is tRNA?
