Cell Biology

Lysosomes are membrane-bound organelles containing digestive enzymes. They are called the "suicidal bags" of the cell because they can digest the cell's own components when the cell is damaged or during programmed cell death (apoptosis).
- Mitochondria produce energy.
- Dictyosomes are part of the Golgi apparatus.
- Plastids are involved in photosynthesis and storage.

ATP (adenosine triphosphate) is primarily formed in the mitochondria, often called the powerhouse of the cell. It is produced through cellular respiration, mainly during oxidative phosphorylation.
- Cytoplasm is where glycolysis occurs.
- Ribosomes are involved in protein synthesis.
- Lysosomes are involved in digestion and waste removal.

Cells can be divided into two parts based on the organization of the nucleus: prokaryotic cells (without a well-defined nucleus) and eukaryotic cells (with a true nucleus). This fundamental classification differentiates cells structurally and functionally.
