Grade 12 IB Biology Summer Assignment
Dear IB Biology Student,
Congratulations you are half way through the IB Biology curriculum! Next year, we will
be covering various topics in the human body as well as other topics.
Your assignment this summer is composed of two parts:
1. IA plan
2. Human body and plant questions
Part 1: IA Plan
Pick a topic we have studied this year or will study next year and design an experiment
for it. Use the design proposal template document to submit your idea to me. Please
read the IA rubric and description in your curriculum guide to be able to come up with
an appropriate experiment plan.
Part 2: Human Body (SL and HL) and Plants (HL only)
Important Note for SL and HL Students:
If you do not write the answers to the assignment below in your own words, you will be
violating the honor code. Do not use any of the IB Biology websites to help you with this
assignment.
Once you are finished with answering the questions below, submit your summer
assignment on turnitin.com. If you are an HL student, you will not need to submit your
drawings on turnitin.com
Both SL and HL
1. For each of the following body systems, write down 5 questions that you want to
know more about:
- Digestive System
- Circulatory/Cardiovascular System
- Respiratory System
- Immune System
- Endocrine System
- Nervous System
- Muscular System
- Reproductive System
- Excretory System
2. Find out more about one of the body systems above and come up with a
presentation tool to present the information. You can do a brochure, movie,
PowerPoint, podcast, or any other method of presentation that you think is
appropriate.

3. Review the material we have covered this year. Go back and try to answer the
questions that you have taken on previous quizzes and tests without looking at
the answers.
For HL only
1. Draw AND label the diagrams of the following:
- The distribution of tissues in the stem and leaf of a dicotyledonous plant.
- The structure of a dicotyledonous animal-pollinated flower.
- The external and internal structure of a named dicotyledonous seed.
2. State five differences between the structure of dicotyledonous and
monocotyledonous plants.
3. What is transpiration? Explain how water is carried by the transpiration stream,
including the structure of xylem vessels, transpiration pull, cohesion, adhesion
and evaporation.
4. Explain how xerophytes have adapted to reduce transpiration.
5. If you were to design an IA related to plant science, what would you do?
