Organic Molecules
What two elements are found in all organic molecules?
What are carbon and hydrogen?
What part of the cell controls what goes in and out?
What is the cell membrane?
Which type of cell has no nucleus: prokaryotic or eukaryotic?
What is a prokaryotic cell?
What is the chemical formula for water?
What is H₂O?
What is the nucleus compared to in the “bagel shop” analogy?
What is the manager’s office or control center?
What are the building blocks (monomers) of proteins?
What are amino acids?
What is the jelly-like fluid inside the cell that holds organelles?
What is the cytoplasm?
What do both prokaryotic and eukaryotic cells have in common?
They both have DNA, ribosomes, cytoplasm, and a cell membrane.
What are the three states of matter?
What are solid, liquid, and gas?
If the nucleus is the manager, what is the cell membrane like?
What is the security gate or door that controls entry and exit?
Which macromolecule stores genetic information in living things?
What are nucleic acids (DNA and RNA)?
What structure gives a plant cell its rigid shape and support?
What is the cell wall?
Which type of organism includes plants, animals, fungi, and protists?
What are eukaryotes?
What is it called when a liquid climbs up a thin tube, as in plants drawing water?
What is capillary action?
What is the cytoplasm compared to in the bagel shop analogy?
What is the kitchen space where materials are mixed and reactions happen?
What is the main difference between a monomer and a polymer?
A monomer is one small molecule; a polymer is many monomers joined together.
What part of the cell contains the DNA and acts as the control center?
What is the nucleus?
What kind of environment do some Archaea live in?
Hot springs, salty lakes, or swamps with little oxygen.
What causes water molecules to stick together, letting insects walk on water?
What is surface tension caused by hydrogen bonding?
Which cell part works like conveyor belts or scaffolding to move materials?
What is the cytoskeleton?
What special lipid forms the double layer that makes up cell membranes?
What are phospholipids?
What is the internal framework of fibers that helps the cell maintain its shape and move materials?
What is the cytoskeleton?
Why are eukaryotic cells considered more complex than prokaryotic cells?
They contain membrane-bound organelles like nuclei, mitochondria, and ER.
Why does ice float on water?
Because ice is less dense than liquid water.
If a cell stopped producing proteins, which part of the cell would likely be malfunctioning?
What are the ribosomes or the nucleus?
