A nice apple tree (Malus Domestica) grows near our house so we decided to measure an area of its leaf and estimate a level of chlorophyll in a leaf. We obtained the next results:
- Estimated time of measurement: less than a minute
- An apple tree leaf area: 6,8 cm2
- Dark green index: 0,52
After that, we began to think about apples.
What type of apple is an Apple company symbol? Or the Tree of Knowledge? Or Sir Isaac Newton’s apple? Measuring an apple leaf surface area (details at http://petioleapp.com) we were thinking about these questions and found that over 8 000 types of apples are on our planet. However, no clues on topics interesting for us… Do you have any extra info about this?
