The male wasp, Campsoscolia ciliata, transfers pollen from one orchid to another orchid of the same species. What "reward" does the male wasp receive from the orchid plants for helping with the orchid pollination?
no reward; the male wasp is deceived by the flower shape and odor
Which of the following plant/animal interactions is not a mutually beneficial (mutualistic) relationship?
wasps such as Campsoscolia ciliata transferring pollen in orchid flowers
Which of the following best describes the ploidy level of a fertilized embryo sac?
There are haploid, diploid, and triploid cells.
A flowering plant with a deleterious mutation in microsporogenesis would most likely
fail to produce pollen
When comparing the mature seeds of a pine tree to an apple tree, which of the following is a correct statement?
Both contain haploid and diploid tissues.
A mature, unfertilized ovule in an angiosperm is the result of
both meiotic and mitotic divisions.
At the conclusion of meiosis in plants, the end products are always four haploid
Which of the following is the correct sequence during the alternation of generations life cycle in a flowering plant?
one sperm is needed to fertilize the egg, and a second sperm is needed to fertilize the polar nuclei.
contains daffodil genes that increase vitamin A content.
Which statement concerning grafting is correct?
Stocks provide root systems for grafting.
Some dioecious species have the XY genotype for male and XX for female. After double fertilization, what would be the genotypes of the embryos and endosperm nuclei?
embryo XX/endosperm XXX or embryo XY/endosperm XYY
A small flower with green petals is most likely
The pollen produced by wind-pollinated plants is often smaller than the pollen produced by animal-pollinated plants. A reason for this might be that
small pollen grains can be carried farther by the wind.
The black dots that cover strawberries are actually individual fruits. The fleshy and tasty portion of a strawberry derives from the receptacle of a flower with many separate carpels. Therefore, a strawberry is
