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
