Question
Chapter 36.4, Problem 2R
Summary Introduction
To review:
The effect of red light and far-red light on seed germination.
Introduction:
Light is an important factor for the growth of plant. It is required for various processes like photosynthesis, seed germination (photoblasty), and flowering. The wavelength of light reaching the plant is sensed by photoreceptors, which in consequence signal the plant to carry out these physiological processes.

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.
correct answer and explanation why please.
The oat coleoptiles of the seedlings above have been modified: either cut or placed in a light-blocking tube. Which ones will stills bend toward a directional light source?
In Sunflower, If the flower is gamopetalous, are the stamens epipetalous? If so, are the stamens inserted on the tube or on the throat of the corolla? Are the stamens connivant or not? If there are as many stamens as petals, are the stamens opposite or alternate with the petals or lobes of the corolla? Split the corolla from top to bottom to determine this.
