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.

They have two anterior flagella.

Part of archegonia that contains a single egg.

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.
