Experimental Plant Variety In order to have a suitable variety of plant types to successfully complete this experiment‚ plant types that contained recognizable traits and that would not easily be pollinated by foreign pollen were chosen. Finding a plant variety with such characteristics allowed better control over the experiment. Twenty-two varieties of pea plants were chosen by first trialing thirty-four varieties. For two years‚ only self-pollination was allowed for each of these thirty-four plant varieties

for plant growth as well as crop physiology. Almost every plant process is affected directly or indirectly by water supply. Plants‚ as one of basic food sources‚ either in nature or cultivations‚ in their growing period‚ require water or at least moisture for germination. Certainly‚ most land plants are exposed to short or long term water stress at some times in their life cycle and have tended to develop some adaptive mechanisms for adapting to changing environmental conditions. Some plants may

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

characteristics of all living organisms. The physiological definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral meristem is present is also considered as growth region. PHASES

Fast Plants By: Kinser Haselhuhn Biology 111 Section Y Professor Brittingham 4/19/13 Abstract: Introduction: Materials and Methods: To begin the fast plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant

Plant Tissues A mature vascular plant (any plant other than mosses and liverworts)‚ contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. Meristematic The main function of meristematic tissue is mitosis. The cells are small‚ thin-walled‚ with no central vacuole and no specialized features. Meristematic tissue is located in • the apical meristems at the growing points of roots and stems. • the
