Question

Name two semi-autonomous organelles
a. Plastid and mitochondria
b. Golgi apparatus and lysosome
c. Lysosome and plastid
D. Lysosome and mitochondria

Answer 1

Hint:
The organelles which can survive on their own, have their own independent genetic material, can independently replicate, during cell division, they pass their own genetic material along with the cellular DNA are termed as semi-autonomous organelles.
However, they depend on the nuclear gene for biogenesis and on ground cytoplasm for biosynthetic activities, they cannot exist independently. Hence, they are called semi autonomous organelles.

Complete answer:
 In order to answer this question we need to have knowledge about organelles, their division and characteristics of the semi-autonomous organelles.
Organelle is a specialized subunit, with specific functions. Organelles are either membrane-bound organelles or non-membrane bound organelles.
There are many types of organelles. They include structures that make up the internal endomembrane system and other structures such as mitochondria and plastids.
Two broad classes of organelles- that contain their own DNA, and have originated from endosymbiotic bacteria:
mitochondria (in almost all eukaryotes)
plastids (in plants, algae).
Mitochondria and plastids have double membranes and own DNA. The organelles which contain their own DNA and reproduce independently of the nucleus are said to be 'semi-autonomous organelles'. They contain DNA as well as ribosomes and are able to synthesise some of its own proteins therefore, are called semi autonomous cell organelle.They also have the ability of synthesizing some of their proteins required for their functioning.
Mitochondria have their own DNA that can replicate independently. They can manufacture some of the proteins required for their functioning with the help of their DNA, RNAs, enzymes, and ribosomes and obtain the others from the cytoplasm. The organelles possess their own ribosomes, called mitoribosomes.

Therefore, the correct answer is a, plastid and mitochondria.

Note: A number of unicellular organisms, such as microsporidia, and diplomonads, have transformed their mitochondria into other structures. Also, mitochondrion has its own independent genome that shows substantial similarity to bacterial genomes.
