Bryophytes Flashcards
Is the gametophyte haploid or diploid?
Haploid.
Is the sporophyte haploid or diploid?
Diploid.
How does the sporophyte create spores?
Meiosis
Where are sperms produced on the gamtophyte?
Antheridia
Where are eggs produced on the gametophyte?
Archegonia.
Are the gametophytes of Bryophytes able to live independently of the sporophytes?
Gametophytes are able to live independently.
Do Bryophytes have vascular tissue?
No.
Where do Bryophytes typically live?
In terrestrial, wet environments.
What organisms are included within the Bryophytes?
Liverworts, Mosses, Hornworts.
What is the sporophyte of a Bryophytes like?
Simple single unbranching sporangium.
What are the sperms of Bryophytes like?
They have two anterior flagella.
What is the Venter?
Part of archegonia that contains a single egg.
What is the neck?
Part of archegonia that provides a passage for sperm entry to the Venter.
What are the chloroplasts of Hornworts like?
More like algae than plants (1 per cell). They also have pyrenoids like algae.
Are the sporophytes of Hornworts completely dependent on the gametophyte?
Not completely. They are somewhat photosynthetic.
Do Hornworts have stomata?
Yes.
Do Liverworts have stomata?
No, but they have pores.
What Bryophyte has a calyptra? What is it developed from?
Mosses. It is developed from the Archegonia.
Do mosses have stomata?
Yes.
What are special cells that only mosses have in the Bryophyte group?
They have specialized water-conducting cells.
Do mosses have pyrenoids? What shape are their chloroplasts?
No. They have disk-shaped chloroplasts.
