Question

How many of the following plant parts exhibit haploidization?

• A. 2.
• B. 3.
• C. 4.
• D. 6.

Answer 1

The correct option is D

6.

The correct option is D.

Explanation for the correct option:

Gemmae:

1. The gemmae are tiny discs of haploid tissue that immediately rise the gametophytes and are disseminated from gemma cups by rainfall.
2. They can also form as an extension from the gametophyte part and are known as exogenous gemmae.

Basidiospores:

1. The reproductive spore known as a basidiospore is created by basidiomycete fungus.
2. This classification contains shelf fungi, rusts, smuts, mushrooms, and more.

Zoospores of Phycomycetes:

1. Fungi belonging to the Phycomycetes class can reproduce asexually as well as sexually.
2. The fungi's mycelium is aseptate and coenocytic.
3. Haplotypes make up zoospores.

Spores of slime molds:

1. The word "slime" comes from the macroscopic slime molds' gelatinous look.
2. Under any unfavorable circumstances, they congregate, and acellular or plasmodial slime molds frequently do this. amoeba-like cells give rise to slime molds at first.
3. These haploid, unicellular amoebae feed primarily on bacteria.

Primary protonema:

1. The spores are what trigger the development of primary protonema.
2. Primary protonema is a haploid that is only involved in spore germination.

Secondary protonema:

1. Rhizoids and stems are the building blocks from which secondary protonema develops.
2. Secondary protonema, a haploid organ, is in charge of the general growth of the gametophytic portion of the plant.

Final answer: 6 plant parts exhibit haploidization.
