L37 Plant_Development

These flashcards cover the key vocabulary and concepts related to plant development as discussed in the lecture.

Indeterminate Growth

Growth in plants that is not limited in lifespan or to a specific size.

Plasticity

The ability of plants to adapt or alter development without a fixed blueprint.

Modular Growth

Plant growth that follows patterns that are repeated over and over again.

Totipotency

The ability of a plant cell to differentiate into all types of cells and develop into a complete organism.

Guidelines of Development

Non-fixed principles that govern how developmental modules behave in plant growth.

Zygotic Embryogenesis

The development of an embryo from a zygote, following a series of defined stages.

Somatic Embryogenesis

The process by which plants develop embryos from somatic cells, not from fertilized eggs.

Cell Division Plate

The structure that forms during cell division to separate daughter cells.

Morphogenesis

The biological process that causes an organism to develop its shape.

Apical Cell

The cell located at the tip of the plant embryo contributing to shoot development.

Basal Cell

The cell located at the base of the plant embryo contributing to suspensor formation.

Positional Information

The spatial cues that instruct cells on their roles in development.

Transcriptional Regulators

Proteins that control the transcription of genes, impacting developmental processes.

Fassiculated Mutant

An Arabidopsis mutant that exhibits a loss of positional interactions leading to disorganized cell groupings.

Knolle Mutant

An Arabidopsis mutant characterized by irregular and incomplete cell divisions due to loss of division control.
