RRB ALP & Tec.
14-08-2018 (Shift-II)
2018
✓ Answer:CMetaphase
During metaphase, condensed chromosomes align at the equatorial plate before being separated.
84
Why are mitochondria considered as a 'weird' organelle?
RRB Group-D
24-08-2022 (Shift-I)
2022
✓ Answer:BBecause they contain ribosomes and DNA
Mitochondria are unusual because they possess their own DNA and ribosomes in addition to being semi-autonomous energy-producing organelles.
85
Alignment of chromosomes in the center of the cell at the equatorial plate constitutes which stage of mitosis?
RRB NTPC
19.01.2021 (Shift-I) Stage-I
2021
✓ Answer:CMetaphase
During metaphase, chromosomes align at the cell's equatorial or metaphase plate.
86
Who discovered a cell?
RRB NTPC
30.12.2020 (Shift-II) Stage-I
2020
✓ Answer:BRobert Hooke
Robert Hooke observed cork under a microscope in 1665 and introduced the term 'cell' for the small compartments he saw.
87
Apart from nucleus of the cell, which two cell organelles have their own DNA and ribosomes?
RRB Group-D
09/09/2022 (Shift-III)
2022
✓ Answer:APlastids and Mitochondria
Plastids and mitochondria contain their own DNA and ribosomes and are partly independent of the nuclear genome.
88
Which of the following cell organelles are responsible for transfer, packaging, and modification of protein and lipids in vesicles?
RRB NTPC
26.07.2021 (Shift-II) Stage-I
2021
✓ Answer:DGolgi apparatus
The Golgi apparatus modifies, sorts and packages proteins and lipids into vesicles for transport or secretion.
89
In plant cells, vacuoles are membrane-bound structures. What is their main role in supporting the function and structure of a cell?
✓ Answer:DProviding rigidity and turgidity to the cell
Plant cell vacuoles help maintain turgidity and store substances such as water, salts, minerals, pigments and proteins.
90
When you put a plant cell, fungal cell or bacterial cell in a very dilute external medium, the plant cell or fungal cell will absorb water but will not burst, whereas an animal cell will burst. Which part of the plant cell helps it withstand the pressure of incoming water?
