1.1.8. NUTRITION
1.1.8.1. Organisms need nutrition for energy for all the other proccesses
1.1.8.2. Nutrition in Plants
1.1.8.2.1. Sunlight + Carbon Dioxide + Water = Oxygen + glucose
1.1.8.2.2. Plants create their own food thus they are seen as autotrophic
1.1.8.3. Nutrition in Animals
1.1.8.3.1. Animals consume other organisms to obtain energy
1.1.8.3.2. Animals use digestion to break down complex molecules into simpler molecules to be absorbed
1.1.8.3.3. Animals obtain their food thus they are seen as heterotrophic
2. Photosynthesis
3. 1.3
3.1. Prokaryotic organisms
3.1.1. Bacteria
3.1.1.1. microscopic single celled organisms
3.1.1.2. they have a cell wall (not cellulose)
3.1.1.3. dont have a nucleus but loops of chromasome of DNA
3.1.1.4. lack mitochondria and other membrane bound organelles
3.1.1.5. some bacteria photosynthesise without chloroplasts
3.1.1.5.1. this is possible because bacteria still contain clorophyl and enzymes necessarry for photosynthesis
3.1.1.6. other bacteria feed on living/ dead organisms
3.1.1.6.1. if they feed on dead organic matter they are known as decomposers
3.1.2. Prokaryote = without nucleus
3.1.2.1. always single celled

4.1.2.2. fungi
4.1.2.2.1. not all are pathogenic
4.1.2.2.2. much more common in plants than animals
4.1.2.2.3. fungal diseases in plants tend to affect the entire crop
