Organelles and Cell Anatomy! Bio Honors and AP Bio Unit 2

Starts

Hi, my name is Haritha and I'm a current junior in high school! I'm a USABO Merit Awardee (top 30% of high schoolers nationwide).
This session, we'll be reviewing cell organelles and their functions! This is a new topic for most high school biology students and a good review for AP Bio students. This review will hopefully set you up for success in cellular respiration/photosynthesis (AP Bio Unit 3), which is typically one of the harder topics in bio (we'll have a session for that soon, too!). I can't wait to see everyone :)
