REPRODUCTION IN ORGANISMS (Part 5)

This one for class 12, back again with lesson 1:

Here we cover the following topics:

Gamete transfer:

• When both gametes are motile
• when one is motile, other is not
• When both are non-motile

& Fertilization:

Internal vs External

and a special case

PARTHENOGENESIS

To understand the above here's the video lecture

Here are the questions based on the lecture above:

1. Name some agents of gamete transfer.
2. Define syngamy? What happens if it fails?
3. Differentiate between internal and external fertilization.
4. What additional preparation is required by an organism performing external fertilization & why?
5. How is reproduction in rotifers unique? Name some other organisms showing similar reproductive strategy.

Ask doubts & share comments. Keep learning. 

REPRODUCTION IN ORGANISMS PART 3

Sexual Reproduction:

Learning Outcomes: 

After watching this video you will be able to:

1. Define and deduce the key features of sexual reproduction 
2. Identify the patterns of sexual reproduction 
3. Classify organisms on the basis of patterns
4. Understand key terminologies related to sexual reproduction 

Also, I’ve uploaded the video lectures on you tube. So hereafter I’ll be sharing links:

I'll also recommend a watch of this wonderful video on Marsupials.

Watch the video, and thereafter I’ll be sharing a few questions based on topics covered.

Happy Learning 

REPRODUCTION IN ORGANISMS PART II

In continuation with our previous discussion about introduction of first chapter, I'm uploading the second part.
In this part we'll be discussing Asexual reproduction: Modes & Significance.
Go through the video and try solving the assignments in between as well as at the end.

Reproduction In Organisms VDO Lecture

Covid 19 has put on hold many things. The one thing it need not derail is learning.

So here I'm uploading lecture for the first topic of #ClassXII Biology Lesson 1, Reproduction In Organisms.
