osmundales (royal ferns) and polypodiopsida (true ferns)

5
New cards

What are the charectaristics of lycopodiophyta?

have microphyllum, strobilus reproductive system, isospores and heterospores, prefer acidic environments

6
New cards

What is the life cycle of lycopodiophyta?

sporophyte generation - gametophyte generation - sporophyte regeneration

7
New cards

How can you distinguish between lycopodiales (club mosses) and selaginellales (spikemosses)

Lycopodiales have spirally arranged leaves and are homosporous. Selaginellales have branched and flat leaves and are heterosporous.

8
New cards

What are the characteristics of sphenopsida (horsetails)?

homoiospores, have sterile and fertile (with strobulus) stems, leaves united into sheaths

9
New cards

What is the equisetum life cycle?

strobilus - sporangiophore - sporangium - spore. after the spore spreading, the fertile roots die.

10
New cards

What is a prothallus?

typically heart-shaped gametophyte stage in the life cycle of ferns

11
New cards

What are the characteristics of ophioglossopsida (adder’s tongue ferns)?

prothallus develops in the soil and has mycorrhizal connections, has sterile and fertile lobes on a plant

12
New cards

Where are the sterile and fertile lobes on ophioglossales?

The sterile lobe is green and looks like a tongue. The fertile lobe is narrow.

13
New cards

Characterize osmundales (royal ferns).

dense clusters at the apical ends of the leaves, sporangia are solitary and don’t form a sorus
