Question

State whether the following statements are true or false.
Members of Zygomycotina and Oomycotina are called the algal fungi because they have many common features with algae especially in the thallus structure and reproduction.
a. True
b. False

Answer 1

Members of division and Oomycotina square measure known as the Protoctista fungi as a result of they need a variety of mutual options with Protoctista particularly within the plant structure and replica. In Protoctista plant structure is thready and in division and Oomycotina the plant structure bears tufts of thready hair called rhizoids. In fungi, karyogamy is seen and plasmogamy doesn't occur.

Complete answer:
Zygomycotina: Fungi within the phylum subdivision Zygomycota square measure known as class Zygomycetes. The class Zygomycetes square measures telluric. {they square measure they’re usually saprotrophs however there are some parasites. The hyphae square measures coenocytic. Septa square measure found solely within the generative structures. The subdivision Zygomycota is usually called quick growing fungi characterized by primitive coenocytic hyphae.

Reproduction in subdivision Zygomycota
When the fusion of 2 hyphae takes place it ends up in the formation of a zygosporangium, a thick-walled structure that's ready for living environmental extremes. Before karyogamy, the zygosporangium contains several haploid nuclei, once karyogamy, it contains several diploid nuclei.

Oomycotina: "Oomycota" word suggests that "egg fungi," and it refers to the big spherical oogonia, or structures containing the feminine gametes. Oomycetes square measure is oogamous, that turn out giant non-motile gametes known as eggs, and smaller gametes known as spermatozoa. fungus insidiosum is that the relevant agent of "swamp cancer" particularly in horses, principally in wet tropical environments.

Hence, the correct answer is option (A).

Note: In division, zygospores square measure sexually created fashioned as a result of plasmogamy between 2 gametangia. Therefore, plasmogamy is seen to occur as in protoctista.
