DELETE Cheat Sheet (DRAFT) by

Developmental biology is the branch of biology that studies the processes by which organisms grow and develop from a single cell into a complex multicellular organism. Developmental biologists investigate how genes and environmental factors interact to shape the structure, function, and behavior of organisms.

This is a draft cheat sheet. It is a work in progress and is not finished yet.

INTROD­UCTION TO PLANT DEVELO­PMENT

Develo­pment
- is the progre­ssion from earlier to later stages in matura­tion. It is the process whereby tissues, organs, and whole plants are produced.
-It involves: growth, morpho­genesis (the acquis­ition of form and struct­ure), and differ­ent­iation.

Growth
-Growth refers to an irreve­rsible increase in mass.

Differ­ent­iation
-The process in which the cells of the apical meristems mature to perform specific functions.

Morpho­genesis
-Morph­oge­nesis is the acquis­ition of form, how a plant or organ acquires its distin­ctive shape or form.

Plant develo­pment is highly plastic

 
Plasticity
- is the ability to change form or shape in response to a change in enviro­nment; no genetic change is involved.

Hetero­phylly
-the phenomenon where a plant species produces leaves of different shapes or forms on the same plant, depending on the enviro­nmental condit­ions.
- is thought to be an adaptation that allows plants to optimize their photos­ynt­hesis and water-use efficiency in different enviro­nmental condit­ions, thus increasing their fitness and survival.
