Nucleus: The nucleus is responsible for the storage, protection, and organization of genetic material (DNA) in eukaryotic cells. It controls and regulates all cellular activities by directing the synthesis of proteins and RNA.
Vacuole: Vacuoles are membrane-bound organelles found in plant and fungal cells. They play both structural and functional roles by regulating the cell's internal pressure, maintaining turgor pressure, storing vital molecules such as amino acids, ions, and water.
Golgi apparatus: The Golgi apparatus receives proteins and lipids from the endoplasmic reticulum and modifies, sorts, packages them into vesicles to be transported to their final destination (such as lysosomes, cell membrane, or secretion outside the cell).
Lysosome: Lysosomes are membrane-bound organelles that contain digestive enzymes. They break down and recycle cellular waste materials, molecules, and cellular structures that are no longer needed by the cell. They also play a role in defending the cell against invading bacteria.
Chloroplasts: Chloroplasts are organelles found in plant and algae cells that are responsible for photosynthesis. They absorb light energy and use that energy to convert carbon dioxide and water into glucose and oxygen. This process is crucial for the production of food and oxygen in the biosphere.
