What is ecology?
The study of living organisms and their environment
100
What are macromolcules
Large molecules that make up all living things
100
What are organelles?
Tiny working parts of the cell
100
What are cells?
The basic units of life
100
What organisms do photosynthesis?
plants only
200
What is a producer? Give an example
An organism that makes it's own food - plants
200
What are the elements in CHNOPS?
Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur
200
What do ribosomes do?
make protein
200
What are two differences between a eukaryotic cell and a prokaryotic cell?
Eukaryotic cells have a nucleus, prokaryotic cells do not. Eukaryotic cells have membrane bound organelles (mitochondria, ect) prokaryotes do not, prokaryotes are only bacteria, eukaryotes are plant, animal and fungi

Why do we breathe? Include the reaction for cellular respiration in your answer
To make ATP!!! Oxygen + glucose -> CO2 + ATP
300
What is an invasive species?
A species that is not native to an area that can disrupt homeostasis
300
What type of macromolecules give us quick energy? give a scientific example
carbohydrates, glucose
300
What are two functions of the plasma membrane and what are two structures it is made of?
barrier to the cell, and regulates what comes in and out (selectively permeable); made of a bilayer of phospholipids and proteins
300
What are three similarities between prokaryotes and eukaryotes?
both have a plasma membrane, ribosomes, and DNA
300
What is the equation for photosynthesis? Can photosynthesis happen without carbon dioxide?
carbon dioxide + sunlight -> oxygen + glucose
400
Where is there the most energy on the food pyramid? Why?
At the bottom because plants get 100% of their energy from the sun. As you go up the food pyramid, each level only gets 10%
400
What macromolecules store energy? What are the monomers?
Lipids, fatty acids
400
List three organelles that plant cells have that animal cells do not
chloroplast, vacuole, cell wall
400
If a student finds a cell in a pond and looks at it under a microscope, he sees that it has NO NUCLEUS, ribosomes, and a flagella. What kind of cell is it?
prokaryotic
400
How to the reactions for photosynthesis and cellular respiration relate to each other?
The products of cellular respiration are the reactants for photosynthesis
500
What is a keystone species? How does removing one influence the food web and disrupt homeostasis?
A keystone species is a top predator in a food web. If they die, the food web cannot regulate itself and all the organisms die. Homeostasis is everything being balanced and if you kill a keystone species, it is no longer balanced
500
Enzymes are macromolecules that provide structure and function inside cells. What type of macromolecule are enzymes?
protein
500
What type of cells have vacuoles? What is their function in the cell?
Vacuoles are found in plant cells and store water. They make plants stand up straight.
500
A student is looking at a new cell under a microscope. He notices a nucleus in the center filled with DNA. What kind of cell is he looking at? Eukaryote or prokaryote?
Eukaryote because it has a nucleus
500
If you put BTB in a solution with carbon dioxide it turns yellow. If we breathe in a tube, what color will the BTB turn? If we put plants in the tube, what will happen to the yellow color and why?
The BTB will turn yellow because we breathe out CO2. If we put plants in, the plants will suck up the CO2 for photosynthesis and the water will turn blue again
