Question

In which of these, syngamy can occur outside the body of the organism?

• A. Fungi
• B. Ferns
• C. Algae
• D. Mosses

Answer 1

The correct option is C

Algae

The correct option is C.

Explanation for correct option:

1. The process of the complete fusion of female and male gametes for the formation of a zygote is referred to as syngamy.
2. External fertilization or external syngamy occurs when fertilization takes place outside the body.
3. This is seen in most of the algae.

Explanation for incorrect options:

Option A:

1. Fungi reproduce asexually by either fragmentation, budding, or producing spores.
2. The formation of asexual spores is a quite common mode of asexual reproduction in fungi and is produced via mitosis, from one parent and generally identical to that parent.

Option B:

1. In these spores are involved in reproduction.
2. Fern has a sporophytic generation that releases spores during the summer.
3. Spores released on a suitable surface are usually moist and in protected areas used to promote germination and then finally grow into gametophytes.

Option D:

1. They do not possess flowers.
2. So, they reproduce via spores.
3. The gametophyte of moss is generally simple or branched and upright.
4. The leaves of the mosses are made up of thickened midribs with no internal air spaces between them.

Final answer: In algae, syngamy can occur outside the body of the organism.
