Syngamy can occur outside the body of the organism in
1 Mosses
2 Algae
3 Ferns
4 Fungi
Explanation:
Sygamy is the process of fusion of male and female gametes to form zygote, fertilisation also takes place outside the body of the organism, and this is external fusion called as sygamy occurs in majority of algae.

Algae possesing gametes similar in size and non- flagellated

Assertion : Isogamy is a primitive type of sexual reproduction. Reason : The gametes are of different sizes.
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
The fusing gametes in the lower forms of algae are alike in size, structure and behaviour, they are indistinguishable as to sex, and such gametes are called isogametes. Sexual reproduction which involves the fusion of isogametes is termed as isogamy; it is a primitive type of sexual reproduction.
