100
List the 5 characteristics of life.
What is ability to reproduce, react to stimuli, are organized, grow and develop, use energy.
100
Describe the basic structure of an atom.
What is protons, neutrons, and the electron shell.
100
Explain what the cell wall does in a eukaryotic cell.
What is provides structure for the cell.
100
What does ATP stand for?
What is adenine triphosphate?
100
Name the layer of the leaf tissue that prevents water loss.
What is the cuticle/waxy layer.
200
State the difference growth and development.
growth: gaining more cells development: changes that will happen
200
Describe a polymer.
What are several monomers together creating long chains.
200
Explain what the cell membrane does in a eukaryotic cell.
What is regulates what goes in and out of the cell (nutrients and waste).
200
List the five reasons that cells need energy.
What are to carry out functions, make new cells, make proteins/enzymes, grow, transport nutrients, get rid of waste, divide, and maintain homeostasis?
200
Name the layer of the leaf tissue that allows gases to come in and out.
What is the stoma.
300
Explain homeostasis.
What is a balanced internal environment that must be maintained for cells to function best.
300
What are the monomers found in proteins?
What are amino acids.
300
Explain what the chloroplasts do in a eukaryotic cell.
What are the site of photosynthesis, chlorophyll (gives plants their green color), and convert light energy into chemical energy (ATP).
300
Label 1-4 on this diagram. file:///Users/student/Desktop/Screen%20Shot%202016-01-13%20at%208.18.02%20PM.png
1. adenine triphosphate 2. adenine 3. phosphate groups 4. ribose (sugar)
300
Name the layer of the leaf tissue that protects the leaf from the elements (like our skin).
What is the epidermis.
400
Explain the difference between producers, consumers, and decomposers.
producers: make own energy from sun consumers: eat other organisms decomposers: absorb from dead organisms
400
What are the 4 groups of macromolecules that make up all life?
What are lipids, carbohydrates, proteins, and nucleic acids.
400
Label at least 5 parts of this cell and state whether it is a plant or animal cell. file:///Users/student/Desktop/Screen%20Shot%202016-01-13%20at%207.51.49%20PM.png
1. mitochondria 2. vacuole 3. nucleus 4. cytoplasm 5. cell wall 6. cell membrane 7. chloroplast
400
Why is ATP especially efficient with energy storage?
What is because phosphate groups have a charge and like charges repel. Three phosphate bonds require lots of energy and transport chemical energy within a cell.
400
Name the layer of the leaf tissue that makes food and holds lots of chloroplasts.
What is the palisade layer.
500
List the organizational levels of living systems (from smallest to largest)
What is atom, molecule, biomolecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
500
Describe the four levels of protein structure.
primary: amino acids bonded as a polypeptide chain secondary: coiled array that are held in place by hydrogen bonds between parts of the polypeptide chain tertiary: chains, coils, or twists that fold and twist to make barrels and/or pockets quaternary: two or more polypeptide chains that are referred to as one molecule
500
Relate 6 out of these 8 terms to a school system: nucleus, endoplasmic reticulum, ribosome, golgi apparatus, lysosome, mitochondria, cell membrane, cytoskeleton.
Answers will vary from group to group.
500
Describe how this diagram shows how ATP formation is cyclical.
Once the ATP energy is used, ADP is available to pick up another phosphate to become ATP again. When the bonds break, energy is released. For it to continue to create energy, the molecule is continuing to change from ATP to ADP.
500
Name the layer of the leaf tissue that has many air pockets and contains the xylem and the phloem.
What is the spongy layer.
