Model of a cell

A cell contains several structures, including:

  1. Nucleus - The cell's control centre, containing DNA and regulating cell activity.

  2. Endoplasmic reticulum (ER) - A network of membranes involved in protein synthesis and lipid metabolism.

  3. Golgi apparatus - A stack of flattened membranes that modify, sort, and package proteins and lipids for transport to other parts or outside the cell.

  4. Mitochondria - The cell's powerhouse, responsible for producing energy through cellular respiration.

  5. Lysosomes - Small, spherical structures that contain digestive enzymes and break down waste and cellular debris.

  6. Vacuoles - Large, fluid-filled organelles that store materials such as water, salts, and pigments.

  7. Microfilaments and Microtubules - Tiny protein fibres that help maintain cell shape and support the cellular movement.

  8. Peroxisomes - Small organelles containing enzymes involved in metabolic processes, including the breakdown of fatty acids and detoxifying harmful substances.
