- Draw a simple diagram illustrating alternation of generations in plants, including the sporophyte and gametophyte generations, spores, gametes (eggs and sperm), meiosis, and fertilization. Be sure to indicate whether each generation or kind of cell is haploid or diploid.This figure summarises the life cycle of a seed plant. The blue circles named A and B represent the sexually mature individual of each phase of the life cycle. 1) What is this life cycle called? 2) Plant B is in the diploid phase. What is another name for this plant? 3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase 4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase 5) If B is the diploid phase, in which phase would you find the nucellus? Write just the letter of the individual corresponding to the correct phase 6) If A is the diploid phase, in which phase would you find the sperm cells? Write just the letter of the individual corresponding to the correct phase 7) If A is the diploid phase, in which phase would you find selection on flower colour? Write just the letter of the individual corresponding…In plant trichomes, is it septate?
- Answer the diagram attached below: Determine the following structures with its ploidy level [Haploid (n) or Diploid (2n)] a) Pine Ovule with Developing Megagametophyte b) Pine Ovule with Mature MegagametophyteA pollen of maize with nuclei labeled P, Q and R fertilized an embryo sac with nuclei labeled S, T, U, V, W, X, Y and Z as shown here. R V Y Synergids U W P Tube nucleus Antipodals Which of the following combinations could be found in the embryo? i) PQR, ii) QRY, iii) VWQ, iv) RY Which of the above combinations could be found in the aleurone layer of the seed? Which of the above combinations could be found in the germinating pollen tube?The leafy, green moss plants that are familiar are gametophytes, haploid plants. This is very different from flowering plants and other seed plants. Does a leafy green moss plant grow from a spore or from a fertilized egg? Does the moss plant have both paternal parent and maternal parent?
- Bolting is when a plant starts to spend its energy on producing flowers. Initial bolting time is figured by the number of days from germination to bolting. Rosette area is figured by the average rosette area of the plant at the time of bolting. Researchers created strains of A. thaliana to have varying somatic ploidy levels to study the resulting phenotypes. The graphs show how initial bolting time and rosette area relate to the number of chromosomes in each strain’s somatic cells. Which of the following best describes how a change in genotype affects the phenotype of A. thaliana? The largest average change in both phenotypes occurred from the 2n to the 4n strain. The largest average change in both phenotypes occurred from the 4n to the 6n strain. A lesser number of chromosomes results in plants with a later initial bolting time. A greater number of chromosomes results in plants that have larger rosettes areas.Explain how plants alternate between haploid and diploidgenerations.Examine the variegated leaf shown in Figure Q14–3.Yellow patches surrounded by green are common, butthere are no green patches surrounded by yellow. Proposean explanation for this phenomenon.
