Question 16

Naked seeds.

Answer 16

Gymnosperms

Question 17

Contained seeds.

Answer 17

Question 18

In __________, the ovule is not surrounded by ovary or fruit.

Answer 18

Gymnosperms

Question 19

The 4 phyla of gymnosperms are:

Answer 19

Ginkophyta, Gnetophyta, Cycadophyta, and Coniferophyta

Question 20

There is only one species in this phylum of gymnosperms.

Answer 20

Ginkophyta

Question 21
