1. collecting data
2. formulating a hypothesis
3. testing the hypothesis,
4. stating conclusions.

Ionic Bond
A chemical bond resulting from the attraction between oppositely charged ions.
Covalent Bond
a bond formed when atoms share one or more pairs of electrons
Hydrogen Bond
Attraction between a slightly positive hydrogen atom and a slightly negative atom.
Organic Chemistry
4 Organic Compounds:
proteins, lipids, carbohydrates, nucleic acids
Carbohydrates
the starches and sugars present in foods
function: short term energy source
example: pasta
Lipids
Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon, hydrogen, and
oxygen.
function: long term energy storage, components of the membrane
example: butter, oil
, Proteins
Chains of amino acid molecules used in all cell functions and body growth
function: structural in hair and skin, digestive enzymes
example: collagen, keratin, silk
Nucleic Acids
DNA and RNA
function: information molecule, hereditary molecule
plasma membrane (cell membrane)
Flexible, selectively permeable (having pores or openings) boundary that helps control what enters
and leave the cell.
Cytoplasm
A jellylike fluid inside the cell in which the organelles are suspended
Nucleus
A part of the cell containing DNA and RNA and responsible for growth and reproduction
Endoplasmic Reticulum
A cell structure that forms a maze of passageways in which proteins and other materials are carried
from one part of the cell to another. They carry materials throughout the cell. The ER is the "transport
system" of the cell.
Smooth ER
That portion of the endoplasmic reticulum that is free of ribosomes.
Rough ER
That portion of the endoplasmic reticulum studded with ribosomes.
Ribosomes
Makes proteins, site of protein synthesis
Lysosomes
An organelle containing digestive enzymes, containing strong digestive enzymes which when released
can break down worn out organelles or food.
Mitochondria
Powerhouse of the cell, organelle that is the site of ATP (energy) production
Vacuoles
Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
