the type of life cycle seen in plants is called

alternation of generation

hetero eukaryotes that digest their food externalles and abosrob the small molecules are refferet to as

fungi

fruits, vegetables, corn, rice, adn wheat are all examples of

angiosperms

during the carboniferious period, forests consisting mainly of ____ produces vast quantities of organic matter, which was buried and later turn into coal

ferns and other seedless vascular plants

deep in the tropical rain forest, a botanist discvoered an unusual plant with vascular tissurs, stomata, a cuticle, flagelleated sperm, conelike reproductive tructures bearings seeds, and an alternation-of-generation cycle. he was very excited baotu this discovery becasue it would be rather unusaul for a plant to hav both

seeds and flagelatted sperm

which of the following plants has a dominant sporophyte generation and a seed but no fruit

pine tree

fungi cannot make their own food, and they cannot move. how fo they fid thigns to eat

the produce huge numbers of tiny spred that spread to nearby food and they grow rapidly into their food sources

unlike most angiosperms, grasses are pollinated by wind. as a consequences, some unnessary" parts of grass flowers have almost disappeared. wih of the foolwing parts would you expect to be most reduces in grass flower

petals

which of the following has a dominant sporophyte generation adn a free living gamophyte generation

a fern

true or false: the stugma is a protective chamber where egg develop

false

what kind of entity is lichen

a assocaition between a fungs and a cyanobacgteria or green algae

mosses are included in a gorup of plants called

bryphytes

the male cone of a pine tree is equivalents in teh function to the _____ of the angiopserm

stamen

the angio sperm plant we see represents the ____ generation, adn the flower produces t _________

sporophyte and gameophyte

byrophytes such as mosses differ from all other plants in that htey

lack vascualr tissue

the haploid phase of the life cycles is shortest in which of the following

angiosperm

the domanant types of seed plants today are

conifers adn angiosperm

a key step in the adaptations of seed pantsto dry land was the evoltuon of

cholorophyll a.

the dominant stage of mosses is the

gameophyte

the ripened ovary of a flower, which is adapted to disperse seeds is called

a fruit

which od the following stages in the life cycles of a maple tree corresponds to the leafy, spongy plants in the moss life cycle

pollen grain and ovule

true or false: fungi are more closely related to plants than to animals

flase

which of the following adaptions to a terrestiral existence is are foudn in ferms

vascualr tissue for nutrietns transport adn support

fungo are found assocatied with the earliest plant fossils. which of the follwing is a way in which fungi may have helped plants become terrestrial

by formins mycorrihical assocaitions and helping early plants to extract mineral nutrients form histile soils

reduction of the gameophyte generateion offerns benifits of

increased protection from damage to DNa and increased ability to deal iwth changes in environemnt due to genetic variation

which of the following correctly describes the alternation of generation in plant life cycles

diploid sporophyte that produce spores by meiosis alternate with gamephyte that produce gamete by mitosis

which part of the life cycle does a pollen grain represent

a male gameophyte

which of teh following functions foes a mushroom perform

production of spores

a mushroom

is a composed of many threadlike filamnts called hyphae

individual fungal filaments are called

hyphae

the heterokaryotic phase of a fungal cucle is

a stage in which hypahe contian two gentically differnt hapoild nuclie

ferns and mosses are similar because

noth have sporophytes that produce hapolid spores

which of the following are true

the elaves of palnts are covered by a waxy cuticle that helpes protoect the leaves of disicciation

where and when deos fertilizatrio occur in the mushroon life cycles

in a mushroom, when nuclei a dikaryotic cells fuse

true or flase: msot fungi have flagelated or ameobiod cells in theri life ccles

false

true or false: current evidence siggst that aniamls and palnts evolved frm a common protst

false
