Which plant structure found in lower plants produces gametes?
a. gonad
b. gametangium
c. ovum
d. sperm

(B). Gametangium.

Explanation:

The plant structure that produces gametes in lower, seedless plants, such as algae is known as gametangium.

Gemetangia that produce female gametes are known as archegonia, while gametangia that produce male gametes are known as antheridia.

These structures form gametes by the process of mitosis as lower plants reproduce asexually.

Thus, the correct answer is option (B).

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

true is the answer : )
