Phylum Hepaticophyta Sexual Life Cycle Flashcards
Thallid Sexual Reproduction
Step 1:
Starts with male and female plants
Antheridiophores and archengoniophores
Step 2:
Gametangia produce gametes
Antheridia make sperm
Archgonia make eggs
Thallid Sexual Reproduction
Step 3:
It rains
Step 4:
Sperm swim to archegonia
Thallid Sexual Reproduction
Step 5:
Fertilization
Step 6:
Sporophyte grows inside archegonium
Foot, Seta, Capsule (or sporangium), Calyptra
Thallid Sexual Reproduction
Step 6 continued:
Anatomical structure purpose?
Foot, Seta, Capsule (or sporangium), Calyptra
Foot = Attachment
Seta = stalk
Capsule = creates spores
Calyptra = protects sporophyte
Thallid Sexual Reproduction
Step 7:
Sporocytes create spores via meiosis
Step 8:
Capsule opens
Thallid Sexual Reproduction
Step 9:
Elaters twitch violently to expell spores
Step 10:
Spores germinate and become male or female gametophytes
