What is the difference between fertilization of pollination?a. Fertilization occurs before pollination. Pollination occurs after fertilization.b. Fertilization is an external mechanism whereas pollination is internal.c. Fertilization if the fusion of male gametes and egg cells within an ovule, pollination is the transfer of pollen grains from the male part of a plant to the female part of a plant. d. Insects, air, and/or animals help complete the fertilization process. Pollination does not require the use of external forces to complete the process.
Which of the following is the correct order of floral organs from the outside to the inside of a complete flower?a. petals → sepals → stamens → carpelsb. sepals → stamens → petals → carpelsc. spores → gametes → zygote → embryod. sepals → petals → stamens → carpels
Arrange the following structures from largest to smallest, assuming that they belong to two generations of the same angiosperm.1. ovary2. ovule3. egg4. carpel5. embryo saca. 4, 2, 1, 5, 3b. 5, 4, 3, 1, 2c. 5, 1, 4, 2, 3d. 4, 1, 2, 5, 3
During the alternation of generations in plants, ________.a. meiosis produces gametesb. mitosis produces gametesc. fertilization produces sporesd. fertilization produces gametes
Sperm cells are formed in plants by ________.a. meiosis in pollen grainsb. meiosis in anthersc. mitosis in male gametophyted. mitosis in the micropyle
In a typical angiosperm, what is the sequence of structures encountered by the tip of a growing pollen tube on its way to the egg?1. micropyle2. style3. ovary4. stigmaa. 4 → 2 → 3 → 1b. 4 → 3 → 2 → 1c. 1 → 3 → 4 → 2d. 3 → 2 → 4 → 1
Double fertilization means that ________.a. flowers must be pollinated twice to yield fruits and seedsb. one sperm is needed to fertilize the egg, and a second sperm is needed to fertilize the polar nucleic. the egg of the embryo sac is diploidd. every sperm has two nuclei
Which of the following is correctly paired with its life cycle generation? (more than one may be chosen)A) anther—sporophyteB) pollen—sporophyteC) embryo sac—gametophyteD) stamen—gametophyte
What does angiosperm mean?
Compare the location of the ovule in the pine and the flowering plant. What is the difference between pollination and fertilization?
Pollinators are said to perform a service for plants. What do they do that plants need?A. Move seeds from one plant to another so the plants can reproduce.B. Most pollinators make honey from the pollen they collect so, really, it is the plant that performs a service for the pollinator.C. Pollinators help to protect the plant from predators by defending flowers.D. Move pollen from one flower/plant to another for sexual reproduction.
