Question
Chapter 41, Problem 9TYU
Summary Introduction
To review:
The structure as well as the function of petals and sepals. Also, the petal and sepal structures in different species on the basis of source of pollination like wind and bumblebees.
Introduction:
Sepals, stamens, carpels, and petals are the main organs of the flowers. The structure, as well as functions of these organs, are well adapted to aid in pollination as well as fertilization.

About 100 years ago, C. E. Bessey developed the hypothesis of the “ranalean” flower. What are some of the characters of this type of flower? Is the ranalean flower wind pollinated or insect pollinated?
What are the advantages and disadvantages of wind pollination? What are the advantages and disadvantages of pollination by animals? Why do both types of pollination persist among the angiosperms?
What are the advantages and disadvantages of self and cross pollination?
How are the structures of the pistil and stamen adapted for successful fertilization?

- What is the difference between self-pollination and cross-pollination? If pollen is transferred from the stamens of a flower to the stigma of the very same flower, is that cross-pollination or self-pollination? If it is transferredfrom the stamen of one flower to the stigma of another flower on the very same plant? If it is transferred from the stamen of one flower to the stigma of another flower on a different plant, but a plant that is a clone of the first one? Animals do not have pollen, of course, but why is it that most animals never have to worry about the equivalent problem of self-fertilization? Why cannot most animals fertilize themselves?arrow_forwardWhat is the evolutionary advantage for a flowering plant to be pollinated with pollen from a different individual plant (of the same species)?arrow_forwardName one plant each where pollination occurs with the help of : a) Water. b) Batsarrow_forward
- What is the mechanism of pollination in gymnosperms and how the size and presence of wings on each grain help affect pollination. Which structures are haploid and which are diploid? Are pollen grains the same as spores? Why would anybody care about the structures of conifer pollenarrow_forwardBoth wind and water pollinated flowers are not very colourful and do not produce nectar. What would be the reason for this?arrow_forwardWhat are the advantages of reduced gametophyte? What is an ovule and what are integuments? What is different between ways pollen can be dispersed?

- What is pollen gain? What is pollinations? What are some different ways pollen can be dispersed?arrow_forwardChrysopogon aciculatus is placed under microscope. When crushed, the seed is visible. Apparently, this species of plant is angiosperm. So how do I draw the diagram of the seed(?) for Chrysopogon aciculatus? Do i have to draw just the seed with a fruit coating or do i have to draw the stamen/ovary/stigma etc of Chrysopogon aciculatus' floret?.
