Hello everyone in this question we need to answer certain questions about plant parts.
00:05
So in first question they are saying that assuming that they all belong to the same plant which of the following sequences describe the structure from largest to smallest.
00:19
So we know that gametophyte is the structure that produces anthedia.
00:28
Okay, that produces enthridia and archigonia.
00:36
Nthridia is the male sex organ and archigonia is the female sex organ.
00:43
And then these produce gametes.
00:47
Okay, so in this order we can see that option number d is correct.
00:54
That says that gametophyte is the largest.
00:58
Organ and then antheridia and then gametes okay again question we need to tell which set contains the most closely related terms so in option a we say megasporangium megaspore okay megaspurangium is in structure that produces this is basically megaspore mother's cell.
01:30
So this produces mega spore, okay, which produces eggs and which produces ovule.
01:42
Okay.
01:43
So all these are female sex organs.
01:49
These are involved in females.
01:52
Okay.
01:53
So here we can see that in option a, they are saying megaspangium, megaspore, pollen and ovule.
02:00
So pollen is produced from microsporangium.
02:05
Okay, so a will be our wrong option.
02:08
Option b says microsporangium, microspor, egg and ov as microsporangium produces microspor, but it produces pollen, not egg.
02:21
So option b is also incorrect.
02:24
In option c, they are saying megasporangium, megaspore, egg.
02:30
Egg and ovules.
02:32
So this is our correct answer.
02:34
In option d they are saying microsporangium, microspor, but then they are saying carpal and ovaries.
02:41
So that is not involved in male sex organs.
02:44
So this will be our wrong answer.
02:46
So our correct answer is option c.
02:49
Okay.
02:50
Now in third question, it has been asked...
