Which of the following statements is correct?
Options
- AFusion of two cells is called Karyogamy
- BFusion of protoplasms between two motile or non-motile gametes is called plasmogamy
- COrganisms that depend on living plants are called saprophytes
- DSome of the organisms can fix atmospheric nitrogen in specialized cells called sheath cells
Correct answer
B. Fusion of protoplasms between two motile or non-motile gametes is called plasmogamy
Step-by-step solution
The sexual cycle in fungi involves the three steps: The fusion of protoplasms between two motile or non-motile gametes is called plasmogamy. Fusion of two nuclei called karyogamy. Meiosis in zygote resulting in haploid spores. Saprophytes feed on dead and decaying organisms. Fungi and many bacteria are saprobiotic. Organisms like Nostoc , Anabaena have specialised heterocysts to fix atmospheric nitrogen.
