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

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
