Types of Cells
Simple, small cell without a nucleus and membrane bound organelles.
What is a prokaryote?
Small structure with a hydrophilic head and two hydrophobic tails.
What is a phospholipid?
The chemical formula for a molecule of water.
What is H2O?
Double Jeopardy
The smallest unit of matter.
What is an atom?
Proteins, carbohydrates, lipids, and nucleic acids are the molecules of life.
What is a biomolecule?
DNA is in paired threads in the nucleus.
What is a eukaryote?
The outer boundary of all cells formed from a phospholipid bilayer, membrane proteins, and cholesterol. Provides structure, maintains homeostasis, and moves materials in and out of the cell.
What is a plasma membrane?
What is a polar covalent bond?
The center of an atom consisting of protons and neutrons.
What is a nucleus?
A large molecule used for short term energy. Composed of C, H, and O in a 1:2:1 ratio.
What is a carbohydrate?
Double Jeopardy!
Used to view cells.
What is a microscope?
The membrane protein that moves large, charged particles across the phospholipid bilayer.
What is a transport protein?
When the water molecules motion slows down due to the decrease in temperature. Hydrogen bonds do not break as often and cause the structure to spread out and expand.
What is ice?
The negatively charged subatomic particle that orbits the nucleus. Determines at atoms reactivity.
What is an electron?
DNA and RNA are examples of biomolecules that store genetic information and consist of CHNO and P.
What is a nucleic acid?
Discovered cells by looking at cork under a microscope.
Who is Robert Hooke?
This molecule is between the phospholipid tails and it prevents the fatty acid tails from tangling and increases flexibility in the plasma membrane.
What is cholesterol?
Double Jeopardy
Movement of water due to solute concentration.
What is osmosis?
What is a molecule?
Building blocks are amino acids that consist of CHNO and sometimes S.
What is a protein?
1. All life is made of cells.
2. The cell is the smallest unit of life.
3. All cells come from pre-existing cells through cell division.
What is the cell theory?
Membrane protein with a carbohydrate chain that is used for cell identification.
What is a marker protein?
The property created by hydrogen bonds that allows for bugs to walk on the surface of water and for many drops of water to form a dome on a penny.
What is surface tension.
A type of bond formed between atoms in a molecule when the electrons are NOT shared equally.
What is a polar covalent bond?
Double Jeopardy
Small structures in a cell that have specific functions. Created when biomolecules work together to form this "little organ."
What is an organelle?
