The life cycle of a plant alternates between a haploid gametophyte generation and a diploid sporophyte generation.

The diploid plant form that produces spores through meiosis.

The haploid plant form developed from a spore that produces gametes through mitosis.

The process of a cell committing to a specific developmental fate, even without displaying differentiated features.

The process of cells becoming specialized in structure and function.

The process of plants forming their characteristic shape and structure.

The region at the tip of a shoot where new cells are produced, allowing for upward growth.

The region at the base of a leaf where new cells are produced, contributing to leaf growth and development.

The region at the tip of a root where new cells are produced, responsible for root elongation.
