Gibberellin promotes both seed germination and plant growth. Researchers hypothesize that the gene GID1 in rice (Oryza sativa) codes for the production of a cell receptor for gibberellin. The mutant variety gid1-1 for that gene leads to rice plants with a severe dwarf phenotype and infertile

to be unbiased. The bean seed will be grown over a period of 6 weeks. Bean seeds are an easy plant to grow‚ and only require sunlight‚ warmth‚ soil and water. That is why we chose to grow it. The characteristics of the bean plant made it an easy pick for us. Bean seeds have similar growth patterns to other plants‚ such as corn. In fact‚ they are so easy to find and grow‚ that even a simple bean found in the grocery store can be fully harvested just as a normal bean seed would. Problem

STUDYING LANDSCAPE PATTERNS (FOCUSES ON THE USE OF GEOGRAPHICAL INFORMATION SYSTEM) WHAT IS GIS? A software program linked to a database containing massive amounts of geographic information. Common tool used in studying the spatial patterns of landscape. This tool was first developed in Canada in the 1960s for the “systematic digitization and scanning of maps‚ analysis of data‚ and output of new map products” (Tulloch 2000).

this would help if one can produce more food. Only one of my trials supported my hypothesis‚ of the plant in normal light will grow more than the plant in constant light. For the design of this experiment‚ I planned to plant two pots with three seeds in each pot. The first pot was to be given constant light. The second pot was to be

The Question or Purpose of our lab is to answer the question “How is the germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the
