Accepted Answer

Carpels

Question 9

Which of the following best describes the evolutionary relationship between fungi, plants, and animals?

Fungi are more closely related to animals than to plants

Question 10

Which adaptation allowed seed plants to colonize dry habitats by eliminating the need for water in sperm transport?

Accepted Answer

Formation of pollen grains

Question 11

Which equation correctly represents the process by which sporophytes produce spores?

Accepted Answer

$$	ext{Sporophyte} \xrightarrow{	ext{meiosis}} 	ext{Spore}$$

Question 12

Which of the following is a key difference between gymnosperms and angiosperms?

Accepted Answer

Phloem

Question 14

Which of the following best explains why tall plants had a competitive advantage during plant evolution?

Accepted Answer

A burr clinging to animal fur

Question 16

Which equation best represents the relationship between surface area and efficiency in the uptake of energy and raw materials?
