Module 11 Flashcards
Sporophyte / gametophyte
Asexual generation / sexual generation
ASexual phase produce spores / sexual phase produce sperm or eggs
Fiddlehead
Coiled frond
Rhizome
Horizontal underground stems
Rhizoid
Root-like structures emerging from the epidermal cells
Microsporophyll & megasporophyll
1 strand of vascular tissue derived from outgrowth of stem (small) & branched vascular system more photosynthesis evolved from flattening of multiple branches
*Specialized spore bearing leaves that are male and female respectively
Syangium
Peripheral part of an arterial trunk which the branches arise in a lower vertebrate
*a compound fruiting unit developed from the lateral fusion of individual sporangia
Sporophyll
Modified leaves that bead sporangia
Sporangia
A receptacle in which asexual spores are formed
Spores
Unit of asexual/sexual reproduction
Cell that is produced for reproduction
Sorus
Cluster of sporangium on underside of sporophylls
Strobilus
Cone-shaped structures on tips of branches
Antheridia
Male gametophyte that produces male gametes
Archegonia
Female gametophyte that produces female gametes
Vascular tissue
Complex conducting tissue formed of more than one cell type
Primarily made of xylem and Phloem
Transports fluid and nutrients internally
Lignin
Rigid, orange polymer provides structure
First vascular plant: traits / adaptation
Completely on land but still needs water
Spores
Lycophyta
Sister group to other vascular plants
Contains lycopodium, selaginella, isoetes
Contains club moss, spike moss, quilwort respectively
Pterophyta
Contains equisetum, psilotum, polypodium, ferns
Contains horsetails, whiskferns, and ferns respectively
Fern life cycle
Homospory / heterospory
Microphyll / megaphyll
Microspore / megaspore
Advantages of the seed
Pollination
