Explain pressure flow hypothesis of translocation of sugars in plants.
Step by step
Solved in 2 steps
- Plants reproduce through various methods. Explain which method helps to create genetic variability in crop plants? Moreover elaborate mechanisms promoting self or cross pollination.Why the transfer to wild plants from crops of genes that provide pesticide and insecticide resistance may have evolutionary consequences? Explain.Explain 2 primary functions of plant leaves. Also provide one example of a modified leaf and explain why the modification has been selected for evolutionarily (what advantage does it provide?)
- Refer to Figure 18. Are the storage roots of sweet potato ( Ipomoea batatas) and the tubers of potato ( Solanum tuberosum) analogous or homologous? Explain the answer brieflyWhy is seed considered as the repository of plant genetic materials of crop species?Explain on how TYR has considerable variety among vastly different species, but can also be extremely similar for closely related species. Also explain how with unlimited resources, we could sample our own data and compare healthy TYR genes with those that have mutations directly. Finally, explain on how the TYR gene plays a crucial role in the melanin biosynthesis process in organisms.
- Plant scientists can use Agrobacterium to put other genes into plant chromosomes. Explain?What exactly allowed for plants to grow larger in structure and size? was it the cellulose microfibrils produced by the rosette-shaped synthase complex?According to data from genome sequences, cytoplasmic dynein is absent in some plants (e.g.,Arabidopsis) and present in others (e.g.,rice).Does this finding surprise you? What else might you do to confirm or refute such a statement? How is it possible that higher plant cells could operate without cytoplasmic dynein?
- how does we know that trees or plants are transpiring base on the experiment of transpiration works in colored rose?Give two examples of modified stems and explain how each example benefits the plant.An important goal of molecular botanists is to insert the genes for nitrogen fixation into crop plants such as corn or wheat. Why would the insertion of such genes be useful? What changes in farming practices would this technique allow?
