Hello students, so today's question is environmental change for plant moving from equatic to terrestrial environment.
00:09
So what are the evolutionary changes that happened? and next question is charophytes and terrestrial plants, sheer common ancestor.
00:16
Describe one similarity between these two groups.
00:20
So first of all, the question is about, first question is about aquatic plant.
00:25
Equatic plant means they are living in water.
00:28
Then they moved to terrestrial environment.
00:31
Trestial means they became land plant and what were the changes required at that time.
00:38
So the basically first part is equatic plant is algae.
00:43
Elgi, basically algae which is chero fita.
00:46
Cherofita means green algae means green algae which is like plants but they are in group protest.
00:55
They are in protista group.
00:57
So the aquatic plant, the aquatic plant, they had no roots.
01:04
They had no roots.
01:06
So the first change that needed was root to sport, to sport the plants on land.
01:14
Plants on land, they needed root system.
01:19
They needed root system for attachment, for attachment, which was not required in the, which was not required in the water.
01:30
Next is they need rigid bodies.
01:34
They need rigid bodies because if we talk about algae, algae is just a phthalous.
01:39
Elgi is just a thallus.
01:42
But in plants there are rigid bodies so that they can hold up themselves...
