Lysosomes and Peroxisomes
Lysosomes
Lysosomes are roughly spherical bodies bounded by a single membrane. They are manufactured by the Golgi apparatus (pathway 2 in the figure).
Lysosomes
The main function of these microscopic organelles is to serve as digestion compartments for cellular materials that have exceeded their lifetime or are otherwise no longer useful.
Lysosomes - Little Enzyme Packages
You will find organelles called lysosomes in nearly every animal-like eukaryotic cell. Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things.
In the late endocytic pathway, it has been proposed that endocytosed macromolecules are delivered to a proteolytic environment by 'kiss-and-run' events or direct fusion between late endosomes and lysosomes.
lysosomes Membrane-enclosed organelles containing digestive enzymes. The lysosomes fuse with food vacuoles and enzymes contained within the lysosome chemically breakdown and/or digest the food vacuole's contents.

Lysosomes and Peroxisomes (of the eukaryotic cell) The cell could not house such destructive enzymes if they were not contained in a membrane-bound system.
Lysosomes
Lysosomes are membrane-bound vesicles containing hydrolytic (digestive) enzymes produced by the Golgi complex.
Lysosomes are membrane-bound digestive organelles that can digest macromolecules (break them down to small compounds) that were taken in from the outside of the cell by an endocytic vesicle.
Lysosomes are the garbage disposals of the cell. They are single membrane bound organelles that are released from the Golgi but stay in the cell.

Lysosomes, shown in Figure 17, are relatively large vesicles formed by the Golgi. They contain hydrolytic enzymes that could destroy the cell. Lysosome contents function in the extracellular breakdown of materials.
Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells. Hydrolytic enzymes of plant cells are more often found in the vacuole.
In a way, they're specialized lysosomes. That is to say that their function is really to handle waste products, and by handle, mean take in waste products and also get rid of waste products.
Unlike lysosomes, which are formed in the Golgi apparatus, peroxisomes usually self-replicate by enlarging and then dividing, although there is some indication new ones may be formed directly.

I-cell disease A lysosomal storage disease in which certain hydrolases are missing from the lysosomes owing to a defect in the synthesis of the lysosomal targeting signal, mannose 6-phosphate.
Organelle (OR-gun-EL) A specialized, membrane-bounded structure that has a specific function in a cell. Examples include the nucleus, mitochondria, Golgi, ER, and lysosomes.
organelle -- n. A membrane-bound structure in a eukaryotic cell that partitions the cell into regions which carry out different cellular functions, e.g., mitochondria, endoplasmic reticulum, lysosomes.
lysosome Cytoplasmic, membrane-bounded organelle that contains digestive and hydrolytic enzymes, which are typically most active at the acid pH found in the lumen of lysosomes.
These substances are organized to constitute the living organelles, as endoplasmic reticulum, ribosomes, chloroplasts, mitochondria, Golgi apparatus, nucleolus, nucleus, lysosomes, vacuoles, and centrosomes.
Finally, Smo did not colocalize with LBPA+ or LAMP-1+ late endosomes/lysosomes (Figures 2F and 2G), even in the presence of leupeptin (Figure 2H). (Incardona, 2002) ...
