Warm-UpWarm-Up
1.1. What organelle is responsible for What organelle is responsible for producing energy within a cell?producing energy within a cell?
2.2. What plant cell organelle uses sunlight What plant cell organelle uses sunlight to make cellular food and store energy?to make cellular food and store energy?
3.3. What animal cell organelle helps transfer What animal cell organelle helps transfer chromosomes during Meiosis and chromosomes during Meiosis and Mitosis?Mitosis?
Bio (organic):
Molecules:
Has to do with life
Makes up everything
Bio (organic) molecules make up EVERYTHING in a cell
Organic molecules Organic molecules areare polymerspolymers
MonomerMono: onemer: molecule
Monomer: one part that makes up a polymer
Polymer Poly: manymer: molecule
Polymer: a large molecule made of many repeating parts
Think!Think!
• What is something you see everyday What is something you see everyday that is made of many repeating that is made of many repeating parts?parts?
Monomer or Polymer?Monomer or Polymer?
A single partA single part
Many repeating partsMany repeating parts
There are 4 major groups There are 4 major groups of bio (organic) molecules: of bio (organic) molecules: carbohydrates, nucleic carbohydrates, nucleic acids, proteins & lipidsacids, proteins & lipids
For each (bio) organic For each (bio) organic molecule, you NEED to know 5 molecule, you NEED to know 5 things!things!
1. AKA (other names): other names it can be called
2. Monomer: name of the monomer
3. Purpose: job in our bodies
4. Examples: things that are that organic molecule
5. Related organelles: what organelle it has to do with
