To analyze:
Why planting potatoes may be preferable to planting potato seeds, and which potatoes must be chosen for planting.
Introduction:
Potatoes can reproduce through both sexual and asexual means.
Explanation of Solution
Potatoes can reproduce sexually, by flowering, pollination and seed production. These seeds can give rise to new plants. However, new potato plants can be obtained by planting potatoes from the parent plant. This is a form of asexual reproduction, and the new plant will be genetically identical to the parent. The farmer can therefore choose to plant potatoes that yield more and are tolerant to environmental stresses. Planting potatoes may be preferable, since the genetic composition of the plant is preserved in asexual reproduction. Potatoes which possess the characteristics that the farmer wants will be chosen for propagation.
Planting potatoes that are adaptable to their environment and tolerant to stresses may be preferable, since the genetic composition of the plant is preserved in asexual reproduction. The farmer will choose the potatoes with the characteristics that she/he wants to propagate in the next crop, such as high yielding or stress tolerant potatoes.

- The physical and purposeful process of crossing the pollen of one plant to the stigma of another plant is known as cross pollination or A self pollination artificial fertilization cross fertilizationarrow_forwardIn ordinary English, we use the word fruit to mean something sweet and juicy; however, the following things are fruits: peanut shells, pea pods, bell peppers,and chili peppers. What is the characteristic that lets us know these really are fruits even though they are not sweet? In contrast, bananas are fruits that do not have this characteristic (they are sterile and new plants must be grown from buds that sprout near the base of the plant).arrow_forwardMany flowers have both anthers and pistils. What prevents self-pollination and later self-fertilization?arrow_forward
- Why do you think plant reproductive biology is important in the improvement of crop plants? Explain in a rational manner.arrow_forwardDanish is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover great numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty. Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.arrow_forwardHow long does it take for marigold/rice/wheat/coconut/mango plants to come to flower?arrow_forward
- 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.arrow_forwardJamie planted a big plot of hardy garden chrysanthemums in his greenhouse during the winter since the day length of winter was short. However, Jamie noticed a small plot of hardy garden chrysanthemums at the corner didn’t bloom. Why?arrow_forwardin a kernel, is it possible to separate the seed from the fruit?arrow_forward
