Study Notes
Basic Biological Concepts
- Cell Theory: The cell is the fundamental unit of life.
- Abiotic Factors: Light is an example of an abiotic factor.
- Adaptation: A trait acquired by an organism, like a chameleon changing color, is an adaptation.
- Evolution: Evolution explains the diversity of life as a result of changes leading to present biodiversity.
- Biology & Society: Biology and societal advancements impact all organisms.
- Homeostasis: Maintaining a stable internal environment in living organisms.
- Heredity: Genetic information is passed from one generation to the next.
- Photosynthesis: Plants use light energy to create sugar and oxygen through photosynthesis.
- The process involves carbon dioxide, water, and light energy.
- The chemical equation for photosynthesis is: 6CO2 + 6H2O → C6H12O6 + 6O2.
- Chlorophyll: A green pigment in leaves crucial for photosynthesis.
- Pollination: Moving pollen from one plant part to another.
- Genetic Engineering: Modifying an organism's genetic makeup.
- Circulation: The heart pumps blood throughout the body.
- Cellular Respiration: The breakdown of glucose to produce energy (ATP).
- The chemical equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O.
- Creation Theory: The theory that living organisms were created by a supreme being.
- DNA: Deoxyribonucleic acid, carrying hereditary information, is present in all cells.
- Energy Source: The sun is the primary source of energy for most life forms.
Cell Structure & Function
- Cell Components: Mitochondria is the "powerhouse" of the cell, responsible for energy production.
- One-celled vs. Multi-celled Organisms: Living things can be single-celled or multicellular, each with unique structures and functions.
- DNA Location: DNA holds our hereditary information.
- Genes: Genes contain the information for a single trait.
Biology Branches and Concepts
- Histology: Histology is not a major branch of biology.
- Major Branches of Biology: The text does not identify other major branches of biology.
Plant and Animal Cells (Incomplete Information)
- A Venn diagram illustration comparing plant and animal cells is missing details.
