So while investigating marine algae, a student identified many fertilized eggs.
00:08
So these are the eggs.
00:09
On further development, these eggs turn to form.
00:14
So these eggs develop to form a blastopore.
00:18
We'll draw like this, the blastopore, where the open end becomes the mouth and it develops into a trocophofore.
00:28
Sorry it is trocop4 larvae which is a free swimming larval form and the trocophole larvae has true silo siloam is called as a body cavity so siloam will form like this so the outer layer will be mesodermal layer and there will be a so this inner layer will become the body cavity siloam means body cavity so this is a true silo.
01:01
So what organism forms this type of embryonic development? so the eggs that develop into blastospair.
01:10
So eggs develop into after they divide, they develop into many stages.
01:17
One stage is blastopore or blastula.
01:22
We'll say blastula, which is a cellular structure...
