- How do organisms reproduce? Well it depends on the organism. We explore the two main types - sexual and asexual and consider the consequences of each.

Your videos are uncomplicated and your platform has helped me in my grades.
You seriously help me out so much with my science! Thank you so much for making these videos, they are so helpful to my work. You help me understand things so much easier and really explain it so well. Thank you Cognito!
who's school sent them links for this vid for final biology paper?

this was very helpful thank you
Thank you for this helpful video
My class love this video it was amazing, we are looking forward to your mitosis video. :-)
Awesome! Thank you!
Thank you so much for your videos.really love your explanation and the animation you use makes fun for learning and understand super easy.❤️❤️
MY EXAM IS TOMMOROW THANKS SO MUCH!
Do you recommend I should buy the Denver nugget jeans study guide to do better in science?
I actually did an experiment to see this. I did one past paper without buying the Denver nugget jeans study guide and then did one without. I kept the time the same (60 minutes) and the past paper topic. I measured the marks I got and the time it took me to complete the past paper. I also repeated the experiment three times and averaged the results. The Denver nuggets study guide improved my result by 2000%.

I’m confused

انا خجلانه اقول لامي عن الدرس اللي اخذنا
They explain how the fertilization part.. but not how the sperm enters the female body
Insightful
You make reproduction lesson way easier more than complicating it.❤❤❤
Nice
Good luck everyone
Questions
1)What way do plants reproduce?
2) How does bacteria reproduce?
3) what does sexual reproduction involve between the male and female gametes?
4)what do we call this?
5) why are there variations in sexual reproduction?
6) What are examples of gametes?
How many chromosomes in a normal human cell?
7) How many chromosomes in a human gamete?
8) How many chromosomes when the gametes are fused together?
9)What is the process called to make gametes?
10) How many parents are needed to reproduce asexually?
11) why is there no variation in Asexual reproduction ?
12) How do Eukaryotic organisms such as plants and fungi reproduce asexually?
13) How do Prokaryotic organisms such as bacteria reproduce sexually?
Wow! 😦 That's a lot of questions alright. I seriously would never have thought of these. Did you find the answers tho?
Maybe these are questions for the chat to answer like a test on what we have learnt in the video. 💗 Anyhow I hope you all have a lovely rest of the day. 😁
answers :
1) both sexually and asexually
2) asexually
3) because sexual rep. needs 2 organisms for reproduction and it involves male and female gamete.
4) Sexual rep. occurs when 2 differ. species produce another organism . Members of 2 different species cannot usually reproduce but if they do, the offspring is called hybrids . Hybrids are not fertile.
5) Variation is the differ. between organisms and cells and in sexual reproduction there are 2 parents needed. That's why variation is needed in sexual rep. .
6) sperm ( male gamete ) and ova/ egg cell ( female gamete) are important and examples of gametes.
7) in normal human cell there are 46 chromosomes and in human gamete there are 23 chromosomes .
8) Each gamete has 23 chromosomes, and when they fuse together the zygote has 46 chromosomes, the full number of chromosomes in humans.
9) MEIOSIS is a process of making gametes .
10) one parent only.
11) There is no variation in asexual variation because there is only one parent needed AND variation is a process done between more than one cell or organism.
12) They reproduce through mitosis.
13) conjugation, transformation, and transduction.
Hope these answers will help you, Kirti P !
@@isl_motto786 correction for 7) human gamete contains 23 chromosomes (Haploid)

I was not that clear about the asexual part of the video just some feedback for next time otherwise amazing as use well
