Question

Is the majority of the fungal mass haploid or diploid explain?

Why are sponges the outgroup of the animal kingdom?

Answer 1

Ans . In the majority of Fungi, all the structures are haploid except the zygote. Nuclear fusion takes place at the time of zygote formation, and meiosis follows immediately. Only in Allomyces and a few related genera and in some yeasts is alternation of a haploid thallus with a diploid thallus definitely known.

Most fungi spend most of their life cycle in the haploid state. They form diploid cells only during sexual reproduction.

In the life cycle of a sexually reproducing fungus, a haploid phase alternates with a diploid phase.

Sponges are similar to other animals in that they are multicellular, lack cell walls etc. Unlike other animals , they lack true tissues and organs, and have no body symmetry.
