Study Notes
Microorganisms as Friends
- Microorganisms are beneficial in many ways, such as:
- Decomposing organic matter, recycling nutrients, and improving soil fertility
- Producing antibiotics, vaccines, and hormones
- Helping to clean up pollutants in the environment
- Aiding in the production of food, beverages, and pharmaceuticals
- Playing a key role in human health, influencing digestion, immunity, and mood
Sources of Energy
- Coal and petroleum are formed from:
- Plant and animal remains that have been buried for millions of years
- Heat, pressure, and time transforming these remains into fossil fuels
- These energy sources are non-renewable and finite
Conservation of Energy
- Energy cannot be created or destroyed, only converted from one form to another
- The law of conservation of energy states that the total energy of an isolated system remains constant
- Energy can change forms, such as from kinetic to potential energy or vice versa
Plant Cell Structure and Function
- A plant cell consists of:
- Cell wall: provides support and protection
- Plasma membrane: regulates what enters and leaves the cell
- Cytoplasm: site of metabolic activities
- Nucleus: contains genetic material
- Chloroplasts: responsible for photosynthesis
- Plant cells perform various functions, including:
- Photosynthesis: converting light energy into chemical energy
- Respiration: generating energy for cellular activities
- Synthesizing organic compounds
- Responding to stimuli and adapting to environments
