All right, so for this question, my apologies about that little stutter, is we're going to be talking about plants, specifically their development, and what interesting sort of phenomenon or factors can heavily play into their specific development.
00:15
For plants, of course.
00:16
So we're talking about plant.
00:18
I think you can give it this s here.
00:20
Plant development.
00:22
And let's just look through the different answers because we need to find which of the following is not, and i'll just say is not important.
00:32
Meaning it could be true, but it doesn't really carry much weight.
00:37
So, for example, for this question, i am using a logetic mouse, but that's not really significant information to help you solve this problem and help us get through it together.
00:50
So which is the following is not important, right? let's look at the different answers and talk about what makes sense.
00:56
So answer a, most plants are sessile.
01:02
Now let's just summarize that by just saying sessile.
01:08
Now, what the heck does sessile mean? because if we don't know this, then it's very difficult to answer this question.
01:14
So when you think about sessile, a better word would just be fixed location or immobile.
01:23
So they can't really move.
01:24
They don't have legs.
01:25
They can't walk around and move to other states or countries.
01:30
They're just kind of where they are.
01:32
And why this is significant is sometimes environmental conditions, which probably is heavily brought upon by humans at this point, but other things as well, potentially fires or droughts, anything like that, can significantly affect their survival or how they grow and things such as predators as well.
01:52
They can't escape, although there's other things they can do, which will talk about more.
01:55
So this definitely is significant.
01:57
So it's not the right answer.
02:01
So let's look at the next answer option.
02:03
So answer option b is the plant cells don't move.
02:09
So we're going to talk about the organism as a whole.
02:10
We're talking about the cells.
02:14
So they don't move relative to one another during development.
02:24
And this is going to, i love these answers because they so beautifully sequence between different topics while hitting on specific points during development is the last part here.
02:34
Let's just finish that here.
02:35
So first of all, is this true? because if it's not true, then it's not even worth considering.
02:40
So first of all, this is definitely true.
02:42
They don't move relative to one another.
02:43
Because what happens with these cells is they're heavily undifferentiated, meaning they don't really, they have a lot of wiggle room for what they can become.
02:51
It's similar to like a stem cell.
02:54
So they don't need to necessarily move to different areas.
02:58
For example, when humans are creating cells, we're developing an arm, that arm cell, that's going to be part of that tissue, needs to go to the arm, needs to move around.
03:06
But in this case, the cells can just proliferate, meaning they can grow rapidly.
03:12
If we need more cells that could potentially become something else.
03:15
So essentially we have a bunch, we just need to make a bunch of blank slates to have different functions rather than, you know, bring one person that can speak a language as a translator.
03:26
That's an analogy i'm going to use, right? so if you have a translator and they speak, they speak the only person in the room that speaks russian.
03:35
And we need someone that speaks russian.
03:37
They're going to be very valuable.
03:39
They're going to be very specific.
03:41
We're going to need them.
03:42
But if all of the translators, if they all speak potentially every language, they all speak russian and spanish and english and japanese as well, then hey, we're good to go.
04:00
It doesn't really matter.
04:00
Everyone can do anything potentially, right? we've got a bunch of all rounders.
04:03
So the cells can proliferate and they can elongate to grow and reach other areas rather than move around.
04:10
So that is true...
