Antheridium
An antheridium is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm).

Apical dominance
Apical dominance is the phenomenon whereby the main, central stem of the plant is dominant over (i.e., grows more strongly than) other side stems; on a branch the main stem of the branch is further dominant over its own side branchlets.

Archegonium
An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete.

Bryopsida
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species.

Cytokinin
Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots.

Fern
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.

Gametangium
A gametangium (plural: gametangia) is an organ or cell in which gametes are produced that is found in many multicellular protists, algae, fungi, and the gametophytes of plants.

Gametophyte
A gametophyte is one of the two alternating phases in the life cycle of plants and algae.

Monoicous
Monoicous plants are those species that bear both sperm and eggs on the same gametophyte.

Moss
Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations.

Plant hormone
Plant hormones (also known as phytohormones) are chemicals that regulate plant growth.

Ploidy
Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.

Protonema
A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage (the haploid phase) of the life cycle of mosses and liverworts.

Thallus
Thallus (plural: thalli), from Latinized Greek θαλλός (thallos), meaning "a green shoot" or "twig", is the undifferentiated vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria.
