Which of this statements is true about the gametophyte tissue that surrounding the pine embryo? A.It attributes as a haploid food reserve. B.It functions as a diploid food reserve. C.It features as a triploid food reserve. D.It is the remnant the the pollen tube. E.It establishes from the blend of a microspore and also a megaspore.
You are watching: After fertilization, the ovary of a flower develops into a:
It attributes as a haploid food reserve. (This gametophyte tissue is a source of nourishment for the embryo.)
All seed tree _____. A.are nonvascular B.are heterosporous C.produce flower D.exhibit a dominant gametophyte generation E.produce antheridia and also archegonia top top the very same gametophyte
Which the the following best describes the function of fruits? A.reward for pollinators B.to distract herbivores from eating the leaves C.protection and also dispersal of seeds D.food storage because that the plant to usage over the winter E.Depending on the tree species, any type of of the noted responses are possible
C.protection and dispersal of seeds (When seeds construct from ovules, the ovary the a flower establishes into a fruit, i m sorry protects the enclosed seeds and also aids in your dispersal through wind or animals)
In a usual conifer, exactly how long does the take because that fertilization to happen after pollination? A.Pollination wake up after fertilization. B.It take away one year. C.The processes are simultaneous. D.It takes one season. E.It takes three years.
C. The takes one year. (It takes practically three year to develop the male and also female gametophytes, carry them together during pollination, and kind mature seed from the fertilized ovules. The period from pollination come fertilization takes about one year of that time.)
After fertilization, the __________ establishes into a seed and also the __________ establishes into a fruit.A.egg ... Ovule B.ovary ... Ovule C.pollen grain ... Ovule D.ovule ... Ovary E.egg ... Ovary
ovule ... Ovary (The integuments that the ovule construct into the seeds coat, which gives rise come the seed, and also the ovary develops into a fruit.)
Which the these frameworks is a separate generation indigenous the tree sporophyte?A.The ovuleB.A masculine gametophyte in ~ a pollen grainC.A seed
B.A male gametophyte within a pollen serial (Review the simple sexual life bike in plants and also the life cycle of one angiosperm.)
The the next seedless loved ones of seeds plants develop one sort of spore that gives rise to a bisexual gametophyte. What go this suggest about the ancestors of particle plants? A.They to be homosporous. B.They to be heterosporous. C.They were bryophytes. D.They produced separate male and female gametophytes. E.They were gymnosperms.
A.They to be homosporous. (The closest family members of particle plants are homosporous, suggesting that particle plants likewise had homosporous ancestors.)
In gymnosperms, the seed coat creates from the integument. In angiosperms, the seed coat develops from the __________. A. Integuments B. Receptacle C. Endosperm D. Mrs gametophyte E. Ovary wall
integuments (The embryo and its food supply are enclosed by a seeds coat created from the two integuments the the ovule.)
When the pollen tube releases 2 sperm cells right into the embryo sac, the union that one sperm nucleus through the egg nucleus and of the other sperm nucleus v two nuclei the the main cell, forming a triploid nucleus dubbed the endosperm
Which among the complying with is true of seeds plants, however NOT true the seedless plants? A.The sporophyte is dependent on the gametophyte. B.A movie of water is vital for sperm to come in call with eggs. C.The spore is the main way of dispersing the offspring. D.The sporophyte is large, and the gametophyte is tiny and independent. E.The gametophyte is reduced and dependent top top the sporophyte.

The gametophyte is reduced and dependent ~ above the sporophyte.(The gametophyte of a seedless vascular plant establishes in the soil together an elevation generation. The minute gametophytes the seed tree are defended from desiccation by being preserved within the moist reproductive tissue of the sporophyte generation.)
In gymnosperms megaspores develop into _____ . A.pollen grains B.female sporophytes C.female gametophytes D.ovulate cap E.male gametophytes
Even despite the gametophyte phase of alternation that generations is lessened in gymnosperms and angiosperms, spores still provide rise to gametophytes
Cellulose-digesting microbe live in the organs of termites and also ruminant mammals. The microorganisms have a home and also food, and their master gain more nutrition from their meals. This partnership is an instance of _____. A.predation B.herbivory C.mutualism D.parasitism E.commensalism
C. Mutualism (The cellulose-digesting microorganisms have a home and also place come live; the hosts get nutrients from the microorganism"s malfunction of cellulose.)
To determine the thickness of a rabbit population, you would require to know the number of rabbits and also _____. A.the birth rate B.the size of the area in which castle live C.the development rate the the population D.their sample of dispersion E.the determinants that limit population growth for the rabbit population
B. The dimension of the area in which they live .(Density is the number of individuals of populace per unit area.)
Which protists are in the same eukaryotic supergroup as land plants? A.green algae B.red algae C.brown algae D.both red algae and green algae E.dinoflagellates
D.both red algae and also green algae (think about the diversity map the the ancestral alga indigenous the notebook)
Select the correct statement about photosynthesis by primary producers.A. Floor plants carry out end 80% of the world"s photosynthesis.C. Cyanobacteria lug out much more of the world"s photosynthesis than protists do.C. Photosynthesis protists and also prokaryotes lug out the majority of the photosynthesis in aquatic communities.
C. Photosynthetic protists and also prokaryotes bring out the majority of the photosynthesis in aquatic communities (Scientists estimate that 30% of the world"s photosynthesis is carry out by aquatic protists. Photosynthesis prokaryotes contribute one more 20%, and also land plants room responsible because that the staying 50%. )
The cell of _____ and _____ have modified mitochondria. A.dinoflagellates ... Metazoans B. Mushroom ... Stramenopiles C. Chlorophytes ... Ciliates D. Diplomonads ...parabasalids E. Euglenozoans ... Alveolates
