Front 1

Explain how vegetative reproduction can produce a new plant. Provide an example.

Back 1

A new plant grows from a plant organ or part of it; liverwort gemmae or rhizome of a frond breaks off

Front 2

How is the sporophyte generation of a moss dependent on the gametophyte generation?

Back 2

for support and most of its nutrients

Front 3

Interpret the function of a plant's reproductive system.

Back 3

continuation of the species

Front 4

Compare and contrast the life cycle of a fern and a conifer.

Back 4

The sporophyte is dominant in both. The fern gametophyte grows from a spore, produces male and female gametes, and is separate from the sporophyte. Conifer gametophytes are within male and female sporophyte cones. Conifers grow from seeds.

Front 5

Why is the term alternation of generations appropriate to describe the life cycle of a plant?

Back 5

The sporophyte generation (2n) alternates with the gametophyte generation (n).

Front 6

Make an events-chain concept map of the life cycle of a fern, beginning with the prothallus.

Back 6

Prothallus —> gametes—> fertilization> diploid zygote -> sporophyte —> spore —> prothallus

Front 7

type of asexual reproduction in plants where a new plant is produced from existing plant organs or parts of organs.

Back 7

vegetative reproduction

Front 8

in mosses, a small, green filament of haploid cells that develops from a spore; develops into the gametophyte.

Back 8

protonema

Front 9

haploid spore formed by some plants that develops into a female gametophyte.

Back 9

megaspore

Front 10

haploid spore formed by some plants that develops into a male gametophyte.

Back 10

microspore

Front 11

the opening in the ovule through which the pollen tube enters.

Back 11

micropyle
