1. 1.2 Cells
Plant and Animal Cells

2. Parts of the Cell
Cells are broken down into their functioning parts = organelles
Cell Organelles
Cell membrane – regulates movement of materials in/out of the cell
Cytoplasm – gel fluid which contains the organelles – mainly water
Nucleus – control centre – contains DNA
Mitochondria – produce energy – power house of the cell
- use cellular respiration and photosynthesis to gain energy
Endoplasmic reticulum – ER – assemble, transport, and store proteins
Golgi body – sorts and packages proteins, makes vesicles
Vacuoles – storage sites
Lysosome – digestion occurs here, break down wastes, food, and worn out parts
Ribosomes- create proteins

Saved in my files in Ch. 1

5. Difference Between Plant and Animal Cells
Plants only have the following parts:
Cell wall – support and protection of the cell
Chloroplasts – location of photosynthesis
Large Vacuoles – contain water and provide turgor pressure for plant support

6. Cell Theory Cells are the basic unit of life
All organisms are made of cells
All cells come from other cells

7. Prokaryotic vs. Eukaryotic
Prokaryotic – simple cells –bacteria
Eukaryotic – membranes around organelles and are more complex – liver cell

8. How do Cells Get Energy?
Metabolism – total of all chemical reactions taking place in our cells
Plants use both and animals only use cellular respiration
PHOTOSYNTHESIS
Light energy + carbon dioxide + water→ glucose + oxygen
CELLULAR RESPIRATION
Glucose + oxygen → carbon dioxide +water + energy
DNA – deoxyribonucleic acid
carries heredity material (genes)

9. Bacteria Over 5000 types Some are harmful – diseases – strep throat
Some are beneficial – produce food for us – cheeses
Grouped by shape:
Cocci – round
Bacilli – rod shaped
Spirilla – spiral

10. Viruses Life cycle of a virus: Virus attaches to specific host cell
Not living
Reproduce only by using a host cell
Life cycle of a virus:
Virus attaches to specific host cell
DNA is injected into the cell
DNA is replicated by the host cell
New viruses are formed inside the cell
The host cell bursts and new viruses are released
