Study Notes
Prokaryotic Cells
- Lack a nucleus and other membrane-bound organelles
- Have a simpler structure compared to eukaryotic cells
- Found in bacteria and archaea
Mitochondria
- Powerhouse of the cell
- Responsible for cellular respiration
- Produces ATP (adenosine triphosphate), the primary energy currency of cells
Golgi Apparatus
- Modifies, sorts, and packages proteins synthesized by ribosomes
- Acts like a post office, directing proteins to their final destination
Anaphase
- Stage of mitosis where sister chromatids separate and move to opposite poles of the cell
- Ensures that each daughter cell receives a complete set of chromosomes
Meiosis
- Cell division process that produces gametes (sex cells) with half the number of chromosomes as the parent cell
- Essential for sexual reproduction and genetic diversity
Ribosomes
- Sites of protein synthesis
- Read messenger RNA (mRNA) and translate it into proteins
Passive Transport
- Movement of substances across cell membranes without requiring energy
- Driven by concentration gradients or pressure differences
Photosynthesis
- Process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose
- Occurs in chloroplasts and uses chlorophyll to capture sunlight
