Concept explainers

Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.

3)The inability to synthesise chlorophyll is a recessive characteristic in tobacco plants. If a tobacco plant know to be heterozygous is self pollinated, and 600 of its seed were germinated, a) how many would you expect to produce albino (completely unpigmented) plants? b) how many would be expected to have the parental genotype? c) why is this cross the only way to produce albino tobacco plants
I need explanation for the why the answer is correct? And why would the other options wrong
3) Some pea plant varieties show reduced growth (pygmy) and abnormal leaf formation (crinkly). Both characteristics are recessive to the normal sized plant and normal leaf. If a plant, heterozygour for both characteristics, is self pollinated and 320 seeds are subsequently collected and germinated, how many of the offspring would you expect to show... a) normal leaves and pygmy size b) crinkly leaves c) normal leaves and normal size d) normal size?

You are studying a plant with tissue comprising both green and white sectors. You wish to decide whether this phenomenon is due (1) to a chloroplast mutation of the type considered in this chapter or (2) to a dominant nuclear mutation that inhibits chlorophyll production and is present only in certain tissue layers of the plant as a mosaic. Outline the experimental approach that you would use to resolve this problem.
