  1. hey mr.T,
    i accidentally found this super awesome video that might be good review for our cell unit? it’s pretty complicated, and goes way too much in depth, but the animations blew me away.


  2. Thank you for this information. Kindly consider adding some images.

  3. Hello,
    I’m new at IB HL biology and I need a good explanation and a good activity (for a beginner – me) for 2.1.5. I have seen this activity online where cheek cells were used, and leaves. I’m a bit confused with the second part of the activities i have read up on.

  4. Ahoy everyone, any source for IB style questions? I am preparing a test and would like to use real IB questions
