Question

Lysosomes are produced by:
A. Golgi apparatus
B. Mitochondria
C. Endoplasmic reticulum
D. Leucoplasts

Answer 1

Hint: Anton van Leeuwenhoek was the first who saw and described a living cell. The cells possess the membrane bound distinct structures called as organelles which perform different functions which collectively contribute to the cell functioning.

Complete answer:
On the basis of the type of nucleus and other cell organelles, cells are divided into two groups: prokaryotes and eukaryotes. Prokaryotic organisms are the organisms which are primitive and have comparatively less developed organelles than the eukaryotic organisms. The eukaryotic organisms have well defined organelles.
In this question, we are asked about the lysosomes, so we will discuss the cell organelle lysosomes.
Lysosomes are the membrane bound small vesicles which are present in cytoplasm. The lysosomes are formed by the packaging of small vesicles in Golgi bodies. Lysosomes are acidic in nature and are responsible for the degradation of large molecules and worn out cell organelles. The lysosomes are rich in hydrolytic enzymes which can degrade any molecule into smaller parts. You will be surprised to know that lysosomes can even digest their own cell by causing programmed cell death or apoptosis. That is why lysosomes are often called ‘suicidal bags’.
Mitochondria are membrane bound cell organelles which are responsible for the production of energy in the form of ATP. These are called the ‘powerhouse’ of the cell.
Endoplasmic reticulum is the cell organelle which lies on the periphery of the nucleus where the modifications of proteins synthesized by the ribosomes take place. Smooth endoplasmic reticulum is responsible for the production of lipids.
Leucoplasts are the colorless plastids of different shapes, size and nutrients. Amyloplasts store carbohydrates, elaioplasts store oils and fats and aleuroplasts store proteins.

Therefore, lysosomes are synthesized by Golgi bodies present in the cell. So option-A is correct.

Note: The cell organelles like chloroplasts and mitochondria contain their own circular DNA and ribosomes. By evolutionary evidences, it is believed that mitochondria as well as chloroplast existed as unicellular organisms but due to the changing environment both of these organelles couldn’t survive as discrete organisms and came into endosymbiont relationship with eukaryotic cells. Since then these are the part of eukaryotic cells.
