Document Summary

5be able to draw and label all part of a perfect flower. Where does each part of a fruit come from?835. 14there will be a couple of questions from the travelling plant video. Specifically, what are each of these parts in the. Antibiotic resistance reading in textbook 25. 4, p. 454-456 (in slides i posted on oaks in case you missed it) 28beak size, shape and body size in finches and moths and birds relate back to those examples. You will not need a calculator for the exam. 31be able to describe each of the patterns of natural selection, give an example of each, and draw representations if necessary. 34be able to describe each of the 3 ways that we define species, reproductive isolating mechanisms and how they relate, and examples of each. How does each occur? (remember word roots can be good to help remember this stuff!!!)

Question 1

The key innovation that allowed for plant survival on land, seenin the first land plants and all others after, but not in thecharophytes, is

Question 1 options:

	fruit.
	vascular tissue.
