Question

"Lysosomes" were discovered by
A) Haeckel
B) Christian de Duve
C) Hugo de Vries
D) Purkinje

Answer 1

Hint: Lysosomes are cell organelles found within eukaryotic animal cells. They have basic functions such as breaking down of cellular wastes and debris.

Complete answer:
Lysosomes was discovered by Belgian cytologist Christian de Duve in the 1950s. Lysosomes originate from membranes of the trans-golgi complex. The lysosomal apparatus, endoplasmic reticulum, golgi complex and secretory vesicles form a system of intracellular organelles delimited by unit membranes.

Let's analyze the options for finding the correct answer.
>Option A: Ernest Haeckel was a german zoologist and naturalist, who discovered thousands of new species and coined new terms in biology such as ecology and phylum. Ernest Haekel is the founder of "recapitulation theory". Lysosomes were not discovered by Ernest haekel. Therefore, this is the incorrect option.
>Option B: Christian de Duve discovered lysosomes. He also discovered peroxisomes. Christian de Duve won Nobel prize in physiology for the discovery of lysosome and peroxisomes. Christian de Duve invented the terms such as autophagy, endocytosis and exocytosis etc.Therefore, this is the correct option.
>Option C: Hugo de Vries was a dutch botanist and one of the first geneticists. He worked in the fields of heredity and was best known for his mutation theory. Lysosomes were not discovered by Hugo de Vries. Therefore, this is the incorrect option.
>Option D: Purkinje was a czech anatomist and physiologist. He is best known for his discovery of Purkinje cells, which are the large brain cells found in the middle layer of the cerebellum. Purkinje didn't discover lysosomes. Therefore, this is the incorrect option.

Thus, the correct answer is option (B) Christian de Duve.

Note:The functions of lysosomes are as follows,
-The major function is to digest and remove waste from the cell.
-It is involved in cell membrane repair.
-It also has a role in response to foreign substances.
