Text Solution

Verified by Experts

(a) A newly formed lysosome containing hydrolytic enzymes is called primary lysosome. Secondary lysosome contains hydrolytic enzymes and some digestible material. A secondary lysosome, after digestion of matter. Contains indigestible matter. Such a lysosome is called residual body.
At times, primary lysosome fuses with damaged or unwanted organelles, forming a large sac called autophagic vacuole.
(b) Lysosome arise from the Golgi complex.
(c) Three kinds of plant lysosomes are spherosomes, aleurone grain and vacuoles. These also contain reverse food materials.

The partially digested food coming from the stomach of a person enters a long and narrow organ A in his body. The organ A receives the secretions of two glands : liver and secretes a greensih yellow liquid B which is normally stored in the organ C. Pancreas secretes pancreatic juice which contains three digestive enzymes D, E and F. The intestinal juice completes the process of digestion of food. The inner wall of organ A has million of tiny finger-like projections G which help in the rapid absorption of digested food into blood stram. The undigested part of food then passes into wider tube H which absorbs most of the water from undigested food. The last part of tube H called I stores this undigested food (or waste) for some time. The undigested food is then passed out though opening J as faeces in the process known as K. (a) Name the organ A.

The organism B takes in the solid food by the process of ingestion, digests a part of this food and throws out undigested food in the process called E.
