Bryophyte Lab Review

Slide 1 Liverwort Thallus	Photos of two different views of thalloid liverworts showing the prostrate thallus growing over the substrate.
Slide 2 Liverwort Antheridiophores and Archegoniophores	Photos showing male and female reproductive structures. The antheridiophore produces antheridia on its upper surface, while the archegoniophores produce archegonia from the lower surface of the finger-like lobes
Slide 3 Liverwort Model Archegoniophore	A model of the archegonophore showing archegonia produced on the lower surface. Each archegonium produces an egg.
Slide 4 Liverwort Archegoniophore, Longitudinal Section	A longitudinal section of the archegoniophore showing archegonia produced on the lower surface. Note the egg with in an archegonium.
Slide 5 Liverwort Model Antheridiophore	A model of the antheridiophore showing antheridia produced from the upper surface. Each antheridium produces sperm.
Slide 6 Longitudinal Section of the Antheridiophore	A longitudinal section of a liverwort antheridiophore. Note the location of the antheridia on the upper surface.
Slide 7 Liverwort Model Sporophytes	A model of the sporophyte showing showing how it develops from the fertilized egg in the archegonium. The spore mother cells in the sporophyte undergo meiosis producing haploid spores.
Slide 8 Longitudinal Section of the Antheridiophore Showing Sporophytes.	Longitudinal section through the archegoniophore showing a sporophyte that has developed from the fertilized egg.
Slide 9 Living Moss, Sporophytes and Gametophytes	Living moss showing green leafy gametophytes and the non-leafy sporophytes.
Slide 10 Living Moss, Sporophytes and Gametophytes	Living moss showing green leafy gametophytes and the non-leafy sporophytes.
Slide 11 Moss Life Cycle	Plastic mount specimens showing male and female gametophytes and a female gametophyte with a sporophyte growing from its apex.
Slide 12 Moss Antheridia	A micrograph of a longitudinal section through a male gametophyte. Antheridia are produced from the upper surface of the male gametophyte. Each of the elongate sac-like structures is an antheridium.
Slide 13 Moss Archegonium	A micrograph of a longitudinal section through a female gametophyte. Archegonia are produced from the upper surface of the female gametophyte. Each of the elongate, somewhat vase-like structure that contains one egg in the enlarged base.
Slide 14 Liverworts and Hornworts, Comparison	A photo of living liverworts on the left and living hornworts on the right. Note the upright horn-like sporophytes produced by the hornwort. The sporophytes in this picture are somewhat dried and withered.
