Know the seven characteristics of living things and three parts of cell theory
Identify and describe the function of the organelles in animal and plant cells
Compare and contrast animal and plant cells
Identify the parts of the microscope and describe the function of each part
Be able to calculate magnification of microscope (eye piece x objective lens)
Identify and describe the levels of organization in organisms (atoms all the way to organisms)
Identify the four basic types of tissues in animals
Concepts You Need To Know- Chemistry of Life
1. Define matter and give one example. Anything that has mass and takes up space. Can be a solid, liquid, or gas. Ex:
water, air, a desk.
2. Describe the relationships between atoms, elements, molecules, and compounds. Atoms are the smallest unit of
matter, and two or more atoms chemically bonded are a molecule. A Compound is atoms of two or more elements
chemically bonded, so while H2 is a molecule, OH is both a molecule and a compound.
3. Describe how matter undergoes change:
physical change: change in form or appearance. Could be a change in state of matter. Ex: freezing water, sharpening
a pencil
chemical change. Changing a material into a new substance. Its properties can change, may give off odor, change in
color, or emit a precipitate. Ex : tarnished silver, rust, burning wood, making toast
6 CO2 + 6 H2O
C6H12O6 + 6O2
To count atoms, remember the number BELOW the element counts only for that element. If the number is
in front of the molecule, multiply it times the number of that element.
The side of the equation WILL balance; atoms are only rearranged.
4. Define (and be able to Identify) the reactants and the number of atoms in it
Reactants are the substance ABOUT to react in a chemical equation, usually to the left of the arrow.
5. Define (and be able to Identify) products and the number of atoms found in it
Products are he substances produced in a chemical reaction and after the arrow.
6. What are the elements commonly found in living things?
Carbon (makes it organic), hydrogen, oxygen, and nitrogen
7. Identify the four major organic compounds, give examples of each and their functions.
Carbohydrates main energy source. Ex: Sugars and starches Source: Grains, fruit, and vegetables.
Proteins Builds and repairs cells. Ex: amino acids and enzymes. Source: Animal products (meats, eggs, daily) legumes
Lipids Source for stored energy. Ex: fats, waxes, and oils. Fats and fatty acids
Nucleic acid Stores genetic info. Ex: nucleotides, DNA and RNA
Concepts You Need To Know- Living Things
8. Describe the seven characteristics of living things All organisms are:
made of cells
react to changes in their environments
made of similar compounds
reproduce
use energy
maintain a stable environment (homeostasis)
grow and develop
9. Describe the three parts of the cell theory
a. All living things are composed of cells.
b. Cells are the basic unit of structure and function.
c. All cells come from pre-existing cells.
10 Identify and describe the function of the organelles in animal and plant cells KNOW YOUR FOLDABLE
11 Compare and contrast animal and plant cells (How are they different? What do they have in common?)
Plant and animal cells share many organelles: nucleus (containing chromosomes), cell membrane, cytoplasm,
mitochondria, endoplasmic reticulum, ribosomes, Golgi bodies, and vacuoles. Plants have a larger central
vacuole, a cell wall, and chloroplasts.
12 Identify and describe the levels of organization in complex organisms
Atom – smallest unit of matter
Molecule- two or more atoms bonded together
Organelles – “tiny organs”, made of macromolecules
CELLS- living thing
Tissue –same kind of cells working together Ex: epithelial, Muscle, Nervous, Connective
Organs
Systems
Organism
13 Describe the four basic types of tissues in animals
Epithelial Covers and protects the cells beneath it (skin)
Nervous – contains cells that generate electrical impulses to other cells
Muscle contains cells that move parts of your body
Connective cell spaced far apart; gives support and acts as storehouse (bones, blood)
14 Identify the parts of the
microscope and describe the function of each part
15 Be able to calculate total magnification of a microscope
Eyepiece X power of objective
coarse adj.
Ex 10X X 40X + 400X
eyepiece
Body tube
fine adjustment
arm
Nosepiece
low power objective
High power objective
Stage
Stage clips
Base
Diaphragm
Mirror
