Question

The presence or absence of certain sub-cellular component in the cells of three organisms (P, Q and R) is given by
Ribosome: present present present
Mitochondria: present absent present
Lysosome: present absent present
Vacuole: many small-sized absent single large sized. P, Q and R most likely be
a. P-frog Q-E.coli R-ginger
b. P-rat Q-yeast R- onion
c. P-E.coli Q- Paramecium R- mushroom
d. P-spirogyra Q-Bacillus R-yeast.

Answer 1

Hint: The cells have an independent existence and it performs all the important functions of life. The cell organelles are the special type of organ present inside the particular type of cell and it executes the specific type of function.

Complete answer:
The cell of the 'P' has all the cell organelle present which means that it is a eukaryote. It also contains many small-sized vacuoles which give a clear explanation that it must be the cell of the animals.
- The cell of the 'Q' represents that it has only the ribosome while all the other cell organelles are absent. As only the ribosome and not all the cell organelles are present in bacteria then it must be the cell of the bacteria.
- The cell of the 'R' represents that it has all the cell organelles present in it and as a reason, this must be eukaryotes while the vacuole in this cell is large-sized and this indicates that this is the cell of the plant.
So, the 'P', 'Q' and 'R' are the frog, E.coli and ginger respectively.

Note: The cell organelles are present in both the eukaryotes and the prokaryotes. Some organelles perform a function as a collection of the energy of the cell and some perform the activity of the cell. Some organelles differ from plants more than animals.
