1

Bryophyte spores are dispersed by:

air

2

The pollen grain is:

the male gametophyte.

3

Pines use _____ to disperse pollen, whereas flowering plants often rely on _____.

wind; animals

4

Which of the following statements is true of the bryophyte gametophyte generation?

It is photosynthetically independent.

5

One of the advantages seeds have over spores is that they contain nutritional resources originating from photosynthesis by the maternal sporophyte that aid in establishment.

true

6

Which of the following statements about angiosperm reproduction is true?

There are a diverse array of flower shapes and colors, largely related to the mode of pollination.

7

In adaptation of plants to life on land, did spores or gametes evolve as the reproductive products for long-distance dispersal, and why?

Spores: A single spore, but not a single gamete, can establish a new individual.

8

Spores: A single spore, but not a single gamete, can establish a new individual.

The spores would dry out more quickly.

9

Which of the following organisms do NOT exhibit alternation of generations in their life cycles?

the green algae Chara and Choleochaete

In plants, _____ are defined as haploid (1n) cells that develop into gametophytes. Gametophytes, in turn, produce either haploid (1n) male or female _____ that can fuse to form diploid (2n) _____.

spores; gametes; zygotes

11

In ferns, the _____ generation is physically larger.

diploid sporophyte

12

Which of the following play the same functional role (establishing new individuals by dispersal)?

fern spores and gymnosperm seeds

13

In angiosperms, a _____ is contained in the anthers or ovaries, and the _____ consists of the rest of the plant.

gametophyte; sporophyte

14

The pollen grain is the:

male gametophyte

15

An ovule can be defined as:

a sporangium protected by sporophyte tissue layers and containing a single non-dispersed spore that has developed into a female gametophyte

16

A fruit is a mature:

ovary

17

If you see a large flower that is white, fragrant, and open at night, it is likely pollinated by a:

bat

18

Which of the following statements is TRUE regarding redwood trees?
