NOTES

Marshall Biology

Chapter 6-2, 7-4

OBJECTIVE:

Understand how the body regulates its functions.

Chemical Change (Reaction)

When an atom or a group of atoms are reorganized into a new substance

TWO PARTS OF A CHEMICAL CHANGE:

·       Reactant:

·       Product:

o   The result of something

Reactant à Product                                                         (à YIELD)

Glucose + Oxygen à Carbon Dioxide + Water

C₆H₁₂o₆ + O₂ à CO₂ + H₂O

BALANCE AN EQUATION:

Based on

Coefficient: Number used to balance an equation

Journal:

1. Distinguish between vesicles and vacuoles
Vesicles: are not an organelle because they don't have a membrane, made in the Golgi apparatus
Vacuoles: store food and waste and have a membrane

2. Name three different ways that animal cells and plant cells differ (think organelles and structure)
Animal Cells
Has Centrioles
Has Lysosomes
No Cell Wall
No Chloroplast

Plant Cells: 
Has cell wall
Has Chloroplast
Larger Vacuoles
No Centrioles
No Lysosomes

3. Due to its close proximity where do ribosomes travel after leaving the nucleus?
The endoplasmic reticulum

4. What is the function of Lysosomes in animal cells?
protection for the cell, digest waste/worn out materials
