How long is the haploid phase of Rhizopus compared to the length of the diploid phase? What are the three main sexually reproducing fungal divisions listed in the manual? Solution 1. Difference between Dinoflagellate and heterokont Dinoflagellate : 2. Most are marine plankton, but they are common in freshwater habitats, as well. 3. Dinoflagellates are considered to be protists, with their own division, Dinoflagellata 4. Dinoflagellates are unicellular and possess two dissimilar flagella arising from the ventral cell side. Heterokont 2. What is a shared character of the radiolarians and Foraminfera? The character of the radiolarians and Foraminfera is “amoeboids with complex shells” 3. How long is the haploid phase of Rhizopus compared to the length of the diploid phase? Haploid life history of Rhizopus (Asexual Reproduction) Once the zygote undergoes meiosis, germination occurs forming mycelia and sporangia with opposite mating strains, (+) and (-). The sproangia produces mitospores which through mitosis developes into gametangia, or sex organs. When the gametangia fuse, syngamy occurs and produces a zygote (2n). The zygote then goes through meiosis to form new 1n spores and the life cycle repeats. Diploid life history of Rhizopus (Sexual Reproduction) The zygospores are the only diploid phase. The zygospore forms from two special haploid hyphae of opposite mating types that touch due to hormones and being in close proximity of each other. The two cytoplasms intermingle, also known as plasmogamy. As this occurs the nuclei of both parents enter the conjunction, causing the resting spore to develop. Karyogamy is the term used to describe the fusion of the two nuclei. After the zygospore has fully formed, meiosis occurs and haploid spores are formed and dispersed. The zygospore can become dormant for severalmonths at a time. Meiosis still occurs and a sporangium similar to the asexually produced sporangium is created when the zygospore finally cracks open. 4. W`hat are the three main sexually reproducing fungal divisions listed in the manual? Sexual reproduction in the fungi consists of three sequential stages Plasmogamy Karyogamy Meiosis.

Solution
1. Difference between Dinoflagellate and heterokont
Dinoflagellate :
2. Most are marine plankton, but they are common in freshwater habitats, as well.
3. Dinoflagellates are considered to be protists, with their own division, Dinoflagellata
4. Dinoflagellates are unicellular and possess two dissimilar flagella arising from the ventral
cell side.
Heterokont
2. What is a shared character of the radiolarians and Foraminfera?

2. The character of the radiolarians and Foraminfera is “amoeboids with complex shells”
3. How long is the haploid phase of Rhizopus compared to the length of the diploid phase?
