Main topics covered in this lecture: 0:03 - Male and female reproductive parts in gymnosperms (microsporangium, megasporangium, microsporophyll, megasporophyll, male cone, female cone) 1:10 - What is an ovule? 2:55 - Reproduction in Cycas / life cycle of Cycas
Hello shanty Miss, Good evening I appreciate your explanation of concepts. In points and gradually climbing up in sequence and where points have connections with one another. Iam a Bio faculty and do watch you tube Bio videos of different online tutors to get insights as well as to go little beyond NCERT text content. Good. Keep it up 👍
Thank you for your comment. In the endosperm of gymnosperms, archegonia develop from a single superficial cell called the archegonial initial at the micropylar end of the endosperm. This archegonial initial undergo division and eventually forms archegonia. I hope this is clear now. Best regards, Shanty
Thank you for the question. In gymnosperms, the female gametophyte is called endosperm while in angiosperms the female gametophyte is called embryo sac. Kindly note the difference. Please watch this video on double fertilization in angiosperms to have more clarity on this topic: th-cam.com/video/Sn7DBm7TqeA/w-d-xo.html. I know this is confusing for many students but now I hope it is clear. Best regards, Shanty

Multiple archaegonia originate from a single endosperm by mitosis .Is this statement right or wrong.
