CELL STRUCTURE
This organelle is known as the control center of the cell.
What is the nucleus?
The movement of molecules from an area of high concentration to an area of low concentration.
What is diffusion?
The process by which one cell divides into two genetically identical daughter cells.
What is mitosis?
This structure controls what enters and leaves the cell.
What is the cell membrane?
A solution with the same concentration of solutes as the inside of the cell is called this.
What is an isotonic solution?
This organelle produces most of the cell's ATP.
What are the mitochondria?
The movement of water across a selectively permeable membrane.
What is osmosis?
During this stage of mitosis, chromosomes line up in the center of the cell.
What is metaphase?
This jelly-like substance fills the inside of the cell and surrounds the organelles.
What is the cytoplasm?
A solution with a higher concentration of solutes than the cell causes water to leave the cell.
What is a hypertonic solution?
This organelle makes proteins and can be found attached to the rough ER.
What are ribosomes?
This type of transport requires cellular energy in the form of ATP.
What is active transport?
During this stage, sister chromatids separate and move toward opposite ends of the cell.
What is anaphase?
These structures are made of DNA and contain genetic information.
What are chromosomes?
A solution with a lower concentration of solutes than the cell causes water to move into the cell.
What is a hypotonic solution?
This organelle modifies, sorts, and packages proteins for transport.
What is the Golgi apparatus?
The movement of substances into the cell by the cell membrane surrounding and engulfing them.
What is endocytosis?
This type of cell division produces gametes with half the normal number of chromosomes.
What is meiosis?
A cell placed in a solution with a higher solute concentration than the cell will lose water. This solution is called what?
What is a hypertonic solution?
A red blood cell placed in a hypotonic solution will do this because water moves into the cell.
What is swell and possibly burst (hemolysis)?
This organelle contains digestive enzymes that break down waste and damaged cell parts.
What are lysosomes?
This process moves substances out of the cell when a vesicle fuses with the cell membrane.
What is exocytosis?
This stage of the cell cycle is when the cell grows and carries out its normal functions before DNA replication.
What is G1 phase?
Programmed cell death that occurs as a normal cellular process is called what?
What is apoptosis?
A red blood cell placed in a hypertonic solution will do this because water leaves the cell.
What is shrink (crenation)?
