Front 2

Derived Traits of seed plants

Back 2

1. Reduced gametophyte
2. Heterospory
3. ovules
4. Pollen

Gametophytes develop from spores________ _________ sporangia (reverse of non-vascular)

Reduced gametophyte is __________ on sporophyte (in both gymnosperms and angiosperms)

Back 3

-retained within

-dependent on

Front 4

One kind of spore germinates into a (usually) bisexual gametophyte

Back 4

Homosporous (most seedless plants)

Front 5

Two kinds of spores leading to MALE and FEMALE gametophytes

Back 5

Heterosporous (All seed plants)

Front 6

Female gametophyte: develops from

Back 6

megaspore inside ovules

Front 7

Male gametophyte:

Back 7

develops from microspores inside pollen grains.

Front 8

Evolutionary advantages of a miniaturized gametophyte stage?

Back 8

Gametophyte small enough to live inside sporophyte:
1. Gametophyte provided with nutrition
2. Gametophyte protected from environmental stress including desiccation and UV radiation (site of meiosis)
3. No need for sperm + egg to be united by droplets of water … allows colonization of dryer areas
4. MALE gametophyte can be dispersed long distances in a small capsule (a pollen grain).

Gymnosperm with only 1 species, tolerates city pollution well

Back 22

Ginkophyta

Front 23

Gymnosperms with gondwana distribution (current distribution due to break up of super contintent Gondwana in Mesozoic. and continental drift to current continental locations.)

Back 23
