Plant and Animal Responses
This topic is externally assessed and worth a whopping 5 credits. See the Achievement Standard for Bio 3.3 here, with extra detail here.
In addition, you will be using this knowledge to help you to complete your 3.1 Internal Assessment investigation at Portobello. See student exemplars here. KAHOOT QUIZ: https://play.kahoot.it/#/k/adecf2bc-4fbb-498b-9ea1-1c4a73fe42b4 Short Answer Practice Questions and Answers
3.1 Practice
Watch the first 30 seconds of the pillbug (slater) experiment on the right and collect data about the speed each individual walks. (Remember speed=distance/time). Assume the petri dishes shown have a diameter of 0.1m. Wet dishes are on the left, dry are on the right. Do not include individuals who cross from left to right or vice versa. Find out what orthokinesis is and a bit about slaters' ecological niche for your discussion. Intraspecific Relationships in Animals
The videos below give a snap-shot of the different types of intraspecific relationships in animals. For each one, think about who is involved, what is at stake, how they communicate and the adaptive advantages of the behaviour for the species as a whole. Aggression Reproductive Behaviour

Plant Responses
Check out these beautiful time lapse videos of plants - are these examples of tropisms or nasties? Can you give their proper names and explain how hormones are controlling what you see?

Plant Hormones
Remembering that plants can't think and act like we animals do, you need to know about the hormones responsible for their growth and timing responses. Here are two videos to help: |

Biology Summary
Hopefully over the past two years, you have acquired enough specialised Biology knowledge to enjoy this treasure of a book: There's a Hair in My Dirt by Gary Larson (yes, he of Far Side fame). It's a great overview of interactions in an ecosystem and I think should make for a nice refresher of the Plant and Animal Response topic. You can either listen to it or put mute on and read it for yourself (it will certainly be faster). Enjoy!
