This question has three parts and we'll be solving them each one by one.
00:04
Now let's look at the first part.
00:06
It says that which is the major distinguishing feature of the fungi and we have the five following options to choose from.
00:13
It says nutrition by ingestion, decomposing dead organisms, prokaryotic cells, absorbing nutrients and sedentary lifestyle.
00:21
Now let's look at the options one by one to see which is the correct answer.
00:25
Now let's look at option a which is nutrition by ingestion.
00:27
Now we actually know that the fungi actually release digestive enzymes and their digestion is actually external.
00:36
Instead of ingesting the material they digested externally to absorb the nutrients.
00:41
So that is wrong.
00:42
What about option b? it's actually correct because they help in decomposing the dead and decaying matter and then they absorb the nutrients from that.
00:51
So it is correct.
00:52
Now option c is also wrong because the fungi are eukaryotic in nature.
00:58
Now option d is partially correct because it do absorb nutrients but it is only from the decomposing dead organisms.
01:06
So it is partially correct.
01:08
So we can say that it's wrong because it doesn't mention the second part of it.
01:13
Now e says sedentary lifestyle.
01:16
It's actually only found in the vegetative state.
01:19
So we can say it's not throughout their life cycle.
01:22
So option e is also wrong.
01:24
And option b will be our final answer which is decomposing dead organic.
01:28
Now let's move on to the second part of the question, which asks us that why fungal infections are more difficult to treat than the bacterial infections.
01:40
And it gives us four options.
01:42
The first one says that the proteins of animal and fungal cells are similar in nature and that's why the antifungal drugs can disrupt both human and fungal cells.
01:53
Option b says that the fungi mutate quickly and develop resistance to these drugs so they can't.
01:59
Not be killed easily.
02:00
Option c says that fungi are multicellular whereas bacteria are unicellular.
02:05
Option d says that the fungi are larger in size so they require stronger drugs.
02:11
Now let's look at these options one by one and analyze them.
02:14
Now the first option says that the proteins of animal and fungal cells are similar.
02:20
It's actually correct because the animal cells and fungal cells are eukaryotic in nature.
02:25
So the eukaryotic cells mostly have similar proteins...
