__________________________ help sieve tube elements unlike xylem, phloem tissue is __________________
 The ___________________ theory explains water movement
 ________________________ is the tendency of water molecules to bond with each other.
_______________________is the tendency of water molecules to bond with other substances.
5. Mosses and their relatives are _____________________________________ plants.
 Nonvascular plants grow close to the ground to absorb water and nutrients. ____________________s plants
rely on ________________________ for reproduction. Produce ______________
 Liverworts belong to phylum ___________________ often grow on wet rocks or in greenhouses can be thallose
or leafy
 Mosses belong to phylum _____________________
6. Club mosses and ferns are seedless vascular plants.
 A _____________________ allows club mosses and ferns to grow higher off the ground. Both need freestanding water for reproduction. Club mosses belong to phylum
_______________________________________________: fern spore-producing organ
7. Seed plants include __________________________ plants and flowering plants.
 Seed plants have several advantages over their seedless ancestors. can reproduce________________ freestanding water, via ____________________. Pollination occurs when pollen meets female plant parts
 ________________ nourish and protect plant embryo seeds allow plants to disperse to new places
 ________________________do not have seeds enclosed in fruit. most gymnosperms are cone-bearing and
__________________________ the __________________________ is reproductive structure of most
_____________________________
 ______________________ is produced in male cones. _______________ are produced in female cones.
________________________ develop on scales of female cones.
8. The largest phylum in the plant kingdom is the flowering plants.
 ______________________ have seeds enclosed in some type of __________________. A __________________
is the reproductive structure of angiosperms. A fruit is a _______________________ of a flower. Angiosperms,
or flowering plants, belong in phylum ________________________
 __________________allow for efficient pollination. Animals feed on pollen or nectar pollen is spread from
plant to plant in process
 A _______________________ is an embryonic
“seed leaf.”
 ________________ have a single seed leaf. leaf
veins usually _______________ flower parts usually
in multiples of __________bundles of vascular
tissue ____________________ in stem
 _________________ have two seed leaves. leaf
veins usually ______________ flower parts usually
in multiples of __________________bundles of
vascular tissue in________________ in stemots
have two seed leaves
9. There are three types of plant life spans.

to compete life cycle _______________________ live more than two years
10. ____________________ allows for efficient seed dispersal. Fruit is flower’s ripened ovary. Surrounds and
protects seed(s) Many forms, each function in _________________________________
11. Flowers contain reproductive organs protected by specialized leaves.
 ___________________________________ are modified leaves. _________________ are outermostlayer that
protects
developing flower ___________________________ can help to attract
animal pollinators
 A ________________________ is the _____________________ structure

_________________ is sticky tip
 ______________________ is tube leading from stigma
to_________________ ovary produces female _______________________
12. Flowering plants can be pollinated by ______________________________
 Flowering plants pollinated when pollen grains land on
______________________. _____________________ pollinated flowers have __________________ flowers
and large amounts of pollen. ___________________ pollinated flowers have ___________________ flowers and
less pollen
 Fertilization takes place within the flower. Male gametophytes, or pollen grains, are produced in the
