Early Land Plants
What are the three clades of Bryophytes?
Liverworts, mosses, and hornworts
what is the protective layer surrounding the ovule?
Integument
This structure anchors the plant, absorbs mineral and water, and stored carbohydrates.
roots
What structure transports water and minerals from roots to shoots.
Xylem
What structure transports photosyntheic products from sources to sinks.
Phloem
What constitutes vascular plants?
Female gametophytes develop from megaspores and males gametophytes develop from microspores
also known as terminal bud and is located near the shoot tip and causes elongation.
apical bud
Apoplast and symplast
this is an aqueous solution high in sucrose
What are the four Derived traits of plants?
Alternation of generations, multicellular dependent embryos, walled spores produced in sporangia, and apical meristems
This mechanism is the transfer of this substance to the part of a seed plant containing ovules is known as
pollination
what leaves have parallel veins. What leaves have branching veins?
Monocots have parallel veins and eudicots have branching veins.
this mechanism allows fro diffusion of free water across plasma membrane determines by water potential.
Osmosis
sugar is moved from a (blank) to a (blank)
sugar source to sugar sink
Why are gametophytes in bryophytes small in height?
They do not have vascular tissues
what structure of the flower is pollen recieved?
Stigma
List the three tissue systems in vascular plants.
Dermal, vascular, and ground tissue
Long distance transport of fluid is facilitated by
bulk flow
phloem loading requires what kind of transport?
active transport
What are the two clades of seedless vascular plants?
Lycophytes and Monilophytes
What are the four floral organs?
Sepals, petals, stamens, and carpels
What tissues produce increase in diameter or stems and roots for woody plants?
vascular cambium and cork cambium.
Transpirational pull
what enables the cells to accumulate sucrose?
Proton pumping and co transport of sucrose and hydrogen.
