In an electrical synapse, the action potential traverses the synaptic cleft directly without involving any neurotransmitters. The adjacent neurons are connected to each other by gap junctions. These gap junctions allow movement of other molecules between the two cells including secondary messengers.
Answer: Mosses gametes are produced by mitosis and ferns gamete are also produced by mitosis.
Explanation:
Mosses and ferns are bryophtes, a group of plants that live in moist habitats and lack true leaves and root.
Mitosis is a form of cell division where a single cell divides to produce two identical daughter cells.
During the life cycle of ferns, the diploid sporophyte produce haploid spores by meiosis. The prothallus of the sporophte produce gametes by mitosis.
In mosses, the diploid sporophyte produce spores from a capsule which open when a small structure operculum degenerates. A single spore germinate to form protenama from which the gametes are produced through mitosis.
