Study Notes
Autotrophs
- Autotrophs are organisms that produce their own food using light (photosynthesis) or chemical energy (chemosynthesis).
- They play a critical role in ecosystems as primary producers, forming the base of the food chain.
Prokaryotic Cells
- Prokaryotic cells lack a nucleus and membrane-bound organelles, differentiating them from eukaryotic cells.
- Their DNA is typically circular and located in a region called the nucleoid.
- Prokaryotes include bacteria and archaea, known for their simple cell structure.
Abiotic Factors
- Abiotic factors are non-living components that affect the environment and ecosystems.
- Examples include sunlight, temperature, water, soil, and minerals.
- These factors influence the health and distribution of living organisms.
Heterotrophs
- Heterotrophs are organisms that cannot produce their own food and depend on consuming other organisms.
- They include animals, fungi, and many bacteria, playing a vital role in nutrient cycling and energy transfer within ecosystems.
Eukaryotic vs. Prokaryotic Cells
- Eukaryotic cells possess a true nucleus containing their DNA, unlike prokaryotic cells.
- They contain various membrane-bound organelles (e.g., mitochondria, endoplasmic reticulum) that perform specialized functions.
- Eukaryotes include organisms such as plants, animals, fungi, and protists, exhibiting greater complexity in structure and function.
