Definitions-final Flashcards
Hydrophyte
Lives in water
Halophyte
Have adaptations to prevent water loss
Facultative halophyte
Do not require saline conditions
Obligate halophyte
Need sodium to complete life cycle
Monocots
1 cotelydon, leaves are parallel blades
Hydrophily
Water mediated pollination
Vivipary
Bearing live young
Heterotrichous growth
Filamentous growth in 2 directions, erect and prostrate
Spermatium
Non mobile male gamete
Carpogonium
Non motile female gamete
Conchocelis
2n sporophyte, filamentous, lives in shells of mollusks
Conchospore
1N spore produced by conchocelis stage
Monospore
1N or 2N asexual spore, develops onto same phase as parent
Carpogonial branch
Filamentous branch where carpogonium form
Trichogyne
Extension of egg, where spermatium attaches
Spermatangial branch
Holds spermatangia
Spermatangium
Male reproductive structure(gametophyte) produces spermatia
Trichoblast
Filament of cells that remains stetile, forms spermatangia or carpogonium
Carposporophyte
Diploid, develops from carpogonoum and spermatium fusion, 2N zygote clones to make carpospores
Pericarp
1n veg tissue, surrounds carposporophyte
Cystocarp
Pericarp and carposporophyte
Carposporangia
Produces carpospores
Gonimoblast
2N filaments, bear carposporangia
All Florideophyceae
Carpospore
Diploid spore(my) by carposporophyte
Tetrasporophyte
Diploid, from germ carpospore, me releases tetraspores
Tetrasporangium
2N me to form 4 tetraspores
Tetraspore
Haploid spore
Connecting/Ooblast filament
Tube, carries zygote nucleus from egg to aux cell, cloned into carpospores
Auxiliary cell
Vegetative 1n receives zygote nucleus after fertilization
Carboxisomes
Bacterial microcompartments that contain enzymes for carbon fixation
Concentrate CO2 for RuBisCo
Trichome
Row of cells(cyanophyta)
Filament (cyanophyta)
Trichome w/n a mucilaginous sheath
False branching
Outgrowth of filament, curves
Trichocyst
Protein rod, can be ejected (miozoa)
Frustrules
Boxlike cell walls composed of silica
Girdle
Area of overlap of frustrules
Raphe
Central groove
