Apr 8, 2015 · Lysosomes are membrane-bound organelles found in animal and plant cells that contain digestive enzymes. They were discovered in 1955 and play key roles in breaking down materials through autophagy, heterophagy, cell death pathways, and more. Lysosomes produce hydrolase enzymes and maintain an acidic interior environment needed for enzymatic ...
Lysosomes are predominantly found in eukaryotic animal cells and are responsible for breaking down cellular debris. In plants, the role of lysosomes is undertaken by the vacuoles as traditional cell biology dictates.

- These figures show the major organelles and other cell components of (a) a typical animal cell and (b) a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells.
- The eukaryotic plasma membrane is a phospholipid bilayer with proteins and cholesterol embedded in it.
- Microvilli, shown here as they appear on cells lining the small intestine, increase the surface area available for absorption. These microvilli are only found on the area of the plasma membrane that faces the cavity from which substances will be absorbed.
- The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs.
Nov 24, 2016 · Function of lysosomes • Lysosomes digest the organic waste that is produced due to the various metabolic activities of the cell. • They play an important function is removing the worn out cell organelles and organic debris by a process called Autolysis.
Apr 13, 2024 · lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms. Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump.
