ANSWER ) MEIOSIS
EXPLANATION
SEXUAL REPRODUCTION CYCLE OF FUNGI
ONCE THE TWO NUCLEI FUSE THIS STAGE IS CALLED KARYOGAMY, LEAD TO PRODUCTION OF DIPLOID ZYGOTE NUCLEUS AND THE STRUCTURE WHICH IS FORM IS KNOWN AS SPORANGIUM. ONCE SPORANGIUM GROW INTO SHORT STALK THE MEIOSIS TAKE PLACE WHICH LEADS TO PRODUCTION OF HALPOID SPORES. THESE HALPOID SPORES ARE RELEASED INTO ENVIRONMENT WHERE THEY GERMINATE AGAIN AND FORM MULTICELLULAR STRUCTURE CALLED MYCELIUM ( HAPLOID CELL). WHEN TWO DIFFERENT MYCELIUM CELL ( HAPLOID) FUSE BUT THERE NUCLEI DO NO FUSE THIS STAGE CALLED AS PLASMOGAMY AND THE CELL IS DIAKARYOTIC CELL WHERE THE DIFFERENT NUCLEI REMAIN IN CELL WITHOUT FUSING. AGAIN THE NUCLEI FUSE AND SEXUAL REPRODUCTIVE CYCLES REPEAT.

Question 11 What occurs during karyogamy in a filamentous fungi? OTwo nuclei fuse. O Spores are released. Hyphae elongate. A sporangiophore develops. O Conidia are formed. Sexual reproduction has never been observed among the fungi that produce the blue-green marbling of blue cheeses. What is true of these fungi and others that do not have a sexual stage? They are currently classified among the ascomycetes. They cannot participate in symbiotic relationships. They do not form heterokaryons, Their spores are probably...

Question 25 1 points The ancestor of land plants is thought to be related to charophytes, a type of green algae. Why might it be advantageous for charophytes to undergo sexual reproduction? a. Charophytes, like land plants, have plasmodesmata, which need to be generated by sexual reproduction b. Sexual reproduction produces larger numbers of offspring in less time. c. They are multicellular when conditions are unfavorable, which favors sexual reproduction d. Sexual reproduction produces multicellular...
