A lysosome functions as the "garbage disposal unit" of a cell, primarily responsible for breaking down and recycling waste materials within the cell by digesting old cell parts, extracellular debris, and invading pathogens using digestive enzymes, thus maintaining cellular homeostasis and contributing to important processes like programmed cell death (apoptosis).
The primary function of a ribosome in a living cell is to synthesize proteins by translating the genetic code carried by messenger RNA (mRNA) into a sequence of amino acids, which then fold to form functional proteins; essentially acting as the site where protein synthesis occurs within the cell.
Centrioles are barrel-shaped organelles in the cytoplasm of animal cells that help organize microtubules and form centrosomes, cilia, and flagella. They are found near the nuclear envelope. Centrioles are essential for the formation of cilia and flagella in living cells. It is a barrel-shaped organelles made of microtubules that play a central role in the formation of cilia, flagella, and centrosomes.
Plastids, organelles found primarily in plant cells, are responsible for the synthesis and storage of important molecules like food, pigments, and other metabolites, with their primary function being photosynthesis, using sunlight to convert carbon dioxide into energy-rich compounds like glucose; they also play a role in the plant's color due to the pigments they store
