Antheridia

This is the male reproductive structure in plants like mosses and ferns. It produces sperm cells.

Apical meristem

This is a region at the tips of roots and shoots in plants where cells are constantly dividing. This helps the plant grow taller or roots grow deeper.

Archegonia

This is the female reproductive structure in plants like mosses and ferns. It produces egg cells.

Dormancy

This is a period when a plant or seed is inactive, almost like it's "sleeping." Dormancy helps the plant or seed survive unfavorable conditions, like WINTER

Gametangium

A general term for any structure where gametes (sperm or egg cells) are produced in plants

Gametophyte

This is the stage in a plant's life cycle that produces gametes (sperm and egg cells). It’s usually haploid, meaning it has one set of chromosomes.

Haplodiplontic

This refers to a life cycle that has both a haploid phase (one set of chromosomes) and a diploid phase (two sets of chromosomes). Most plants have this kind of life cycle.

Heterospory

his means that a plant produces two types of spores: large ones (megaspores) that develop into female gametophytes and small ones (microspores) that develop into male gametophytes.

Homospory:

This means that a plant produces just one type of spore, which can develop into a gametophyte that makes both sperm and eggs.

Megaspore

A large spore that develops into a female gametophyte in plants that exhibit heterospory.

Microspore

A small spore that develops into a male gametophyte in plants that exhibit heterospory.

Pollination

the process where pollen (male gamete) is transferred to the female part of a plant, enabling fertilization.

Sporangium

A structure where spores are produced in plants, fungi, and some

Spore

A reproductive cell that can develop into a new organism without the need for fertilization. Spores are typically produced by plants, fungi, and some protists.

Sporocyte

cell that undergoes meiosis to produce spores.

Sporophyte

The stage in a plant's life cycle that produces spores. It’s usually diploid, meaning it has two sets of chromosomes.
