Ch 15 Flashcards
Characteristics of neophytes
Small Lack true seed, flowers, leaves Hair like rhizoids instead of roots Depend on moisture to reproduce Occupy niches
Bryophyte
Non vascular plants
Lacks vascular tissues
Which is the oldest bryophyte
Liverworts
Which bryophyte is most similar to vascular plants
Moss
Three types of brophytes
Liverworts
Hornworts
Mosses
Tracheophytes
Vascular plants
Literally tube plants
Vascular tissues
Xylem
Phloem
Xylem
Transports water and dissolved minerals from roots to stems and leaves
Consists of dead cells that lack end walls between adjacent cells
Side walls are thick and reinforced with lignin
Stiff and water proof
Phloem
Transports food (sugar dissolved in water) from photosynthetic cells to other parts of the plant for growth or storage Consists of living cells that are separated by end walls with tiny holes
What did vascular plants evolve to have
True roots
Stems
Leaves
Spermatophytes
Plant that reproduces using seeds
Parts of a seed
Embryo
Seed coat
Stored food
Endosperm
Food inside a seed that keeps embryo nourished until it can start making its own food
Gymnosperm
Seeds in cones
Don’t have ovary
1,000 species
Angiosperm
Seeds in ovarys of flowers
Do have ovarys
Hundreds of thousands of species
My have fruits
