Difference between archegonium and antheridium. -Biology

Last Answer : (1) One Explanation: Archegonium is the female reproductive organ in ferns and mosses. The upper part of the archegonium, the neck, consists of four rows of cells containing central neck cells. The uppermost ... the lowest cell is the ventral canal cell. It has one neck canal cell with two nuclei.

The sexual reproductive organs of aspergillus are – (1) Spermatium and Oogonium (2) Antheridium and Oogonium (3) Spermatium and Ascogonium (4) Antheridium and Ascogonium

Description : The sexual reproductive organs of aspergillus are – (1) Spermatium and Oogonium (2) Antheridium and Oogonium (3) Spermatium and Ascogonium (4) Antheridium and Ascogonium

Last Answer : (4) Antheridium and Ascogonium Explanation: Sexual reproduction in Aspergillus is rare and takes place in favourable conditfons. Sex organs are produced on the same mycelium which has produced conidia. Male ... of archicarp as a result of which they become spirally coiled and their tips get fused.
