Biology

Harvard University Department of Organismic and Evolutionary Biology

OEB is in the scholarly pursuit of a broad range of research and teaching interests. These many reports span field and laboratory studies that are key to understanding the evolution of organisms, how biodiversity is generated and maintained, how organisms work, and how organisms interact with their environment.  These also span from the evolution and control of gene expression patterns within individuals and populations to the dynamics of ecosystems.

Vegetative Growth

The period of growth between germination and flowering is known as the vegetative phase of plant development.  During the vegetative phase, plants are busy carrying out photosynthesis and accumulating resources that will be needed for flowering and reproduction.  Different types of plants show different growth habits.  The movies in this link will document various growth processes that occur during the vegetative phase of development.
