1. Why was Karl Linnaeus important to the history of botany as a science?
Because his idea of grouping plants in families was unique. The identification of different species was based on the arrangement of the female and male organs in the flowers.
![Page 34: Unit4 Green world Rose lily Tulip Sunflower Peony the Chinese national flower](https://reader031.vdocuments.us/reader031/viewer/2022012918/551b673d5503465c7e8b65a9/html5/thumbnails/34.jpg)
2. How did scientists classify plants before Linnaeus?
They classified plants into trees and herds according to the shape of the fruit and whether they had flowers or not.

3. Why did Joseph Banks have to supply his own money to equip part of the expedition?
Because the government would not pay for such a new field of science as botany.
