GCSE Biology Paper 1 Revision

This video is for both Combined Science and Biology Only (aka Triple) - the parts that are Biology Only are labelled with a bubble and the parts that are Higher Tier are also labelled!

I hope you find it useful - you can probably see that it has taken me hooooours to create! So please help me out by subscribing & sharing with your friends! Thank you :)

And good luck for your GCSEs & beyond! Try your best, believe in yourself and your effort will pay off :)

any1 currently in y11 rn watching ?
edit : this i my most liked comment zalagalahair to everyone and inshaa allah we all do good in our exams

[iggeee]

I have my Paper 1 Biology test on Tuesday. It is thanks to people like you that help me and thousands of other students to achieve what they are going for. Thank you

[WiCkEdGaMeRYT]

You’ve taught me more in 2 and a half hours than any science teacher has in the space of 5 years

[karmarama]

Good luck to everybody doing this paper tomorrow!

Hi, I just recieved my GCSE results and I'm happy to say I got a 9 in Biology. I watched your videos to revise last minute and they really helped me to remember all the key concepts I needed. I never expected to get such a high grade, and I always felt like I struggled with science, so I want to say thank you for your help. I also wanted to encourage anyone else who finds science really hard, like I did. You can do it, even if it feels impossible! Keep working hard, you are awesome.

[uzier]

you should be revising ahk scroll back up

[qwq]

its about 11hours away from the exam and im now watching⋯⋯

[ally]

good luck to everyone having their paper 1 in two days!! (only revision ive done so far im so cooked)

[zoepetsas]

I literally have my science GCSE in 2 days thanks for helping me out :)

[fineartdocumentation]

Lol I’m watching this over and over agin before my biology mock

[RLs]

Good luck for your biology gcse in a couple days, we got this

[tokyokoro]

watching this the night before my exam will comment how it went

[angel]

This video is super easy to understand and I found the bright bold pictures helped me especially since I’m a visual learner. Great vid. Not boring and I was engaged

[rahh]

2:43 - microscopy
9:40 - acrosome, axon, lignin, sieve plates, companion cells, dendrites
16:56 - 3 factors that affect the rate of diffusion (temperature, concentration gradient, surface area)
20:23 - hypotonic, isotonic, hypertonic
27:13 - mitosis
stage 1: cell increases in mass, cell increases its sub cellular structures. stage 2: nucleus divides into two, one set of chromosome is pulled by cell fibres to opposite ends. stage 3: cytoplasm and cell membrane divides into two
34:07 - stem cells in plants (immuno-suppressant drugs so that the immune system doesn't reject)
57:21 - enzyme table
58:42 - where enzymes are made
1:07:08 - how fish are adapted
1:22:25 - factors that increase the risk of communicable diseases
1:25:21- cancer
1:28:16 - xylem and phloem TABLE IMPORTANT
1:29:42 - transpiration, guard cells become turgid (full of water) and flaccid (when they lose the water), water evaporates from the air spaces of the spongy mesophyll, the water vapour leaves through the open stomata.
1:33:35 - how plants reduce transpiration
1:35:02 - experiment
1:40:20 - viral diseases
viruses: 1:41:17: measles 1:42:24 HIV 1:43:15 TMV
1:48:04 - human defence system
1:55:38 - discovery and development of drugs
1:57:45 - TED = TOXICITY EFFICACY AND DOSAGE
2:16:13 - hard photosynthesis grap
2:19:57 - green house (paraffin heaters release heat and co2)
2:22:46 - fosraac
2:30:58 - lipids= 1 glycerol + 3 fatty acids

tysmm I used this video for my year 10 and 11 mocks and got 9s in both. Hopefully I can maintain that for tomorrow 🙏

[cas_user]

Currently 6:13 AM skimming over the content for the last time. Good luck to everyone! We'll get through these 4 weeks. Thank you for re-teaching the content for people like me Ms.Emma.

[pinkyp-nky]

I have my first exam on Friday, so I'm gonna rewatch this video a bunch
