Students have asked these similar questions
Under which of the following conditions would pollen from an S2S5 plant successfully pollinate an S1S5 flower?
a. Using pollen from a carpelate flower to fertilize a staminate flower would be successful.
b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful.
c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful.
d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.
What is the relationship between pollination and fertilization in flowering plants?
Select one:
a. Fertilization precedes pollinations.
b. If fertilization occurs, pollination would be unnecessary.
c. Pollination brings gametophytes together so that fertilization can occur.
d. Pollination easily occurs between plants of different species.
Suppose that 100 pollen grains land on a stigma, and 50 mature seeds are formed in the fruit. What does this indicate about the pollination process and success?
A) 100% success: 100 pollen grains grew to 50 ovules, two to each, and double fertilization occurred.
B) 100% success: Only 50% of the pollen grains germinated, but each produced 2 sperms to complete double fertilization in 50 seeds.
C) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei.
D) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 100 polar nuclei.

- What are chasmogamous flowers? Can cross-pollination occur in cleistogamous flowers? Give reasons for your answerarrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forwardWhich of the following is True?a. Ethylene stimulates abscission layers to form.b. Abscisic acid causes abscission layers to form.c. Ethylene is sometimes sprayed on flowers to keep them fresh.d. Abscisic acid stimulates seed germination.arrow_forward
- A plant biologist discovers a new species of plant in the ashes of a recent forest fire along the sides of a steep mountain range. It is fall, and temperatures are dropping below freezing. The biologist cannot stay in the field to observe the plant. What can he infer about the plants reproductive strategy based on his recent observations? A) the plant will produce flowers because at this altitude there is sufficient sunlight B) the plant will produce comes because cones will mature into adult plants more rapidly C) the plant will produce cones because cones allow for seed dispersal through all seasons D) the plant will produce flowers because flowers can protect the seed from extreme conditionsarrow_forwardUsing the illustration and the assumption that half of a plant's sperm and eggs are p and half are P, one can predict that the chance of sperm p meeting egg P at fertilization is ____. 25% 75% 1/2 x 1/4 50% 100%arrow_forwardDouble fertilization is a) fertilization of an egg by two sperm. b) fertilization of two eggs by the same sperm.
