How the plants grow towards light and why this response is adaptive. Concept introduction: Flowering in plants is associated with the photoperiod or the day length. On the basis of length of the light a plant requires, plants are categorized as long-day or short-night plants, short-day or long-night plants, and day-neutral plants.

This figure summarises the life cycle of a seed plant. The blue circles named A and B represent the sexually mature individual of each phase of the life cycle. 1) What is this life cycle called? 2) Plant B is in the diploid phase. What is another name for this plant? 3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase 4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase 5) If B is the diploid phase, in which phase would you find the nucellus? Write just the letter of the individual corresponding to the correct phase 6) If A is the diploid phase, in which phase would you find the sperm cells? Write just the letter of the individual corresponding to the correct phase 7) If A is the diploid phase, in which phase would you find selection on flower colour?

We used seedlings of Lepidium sativum to see under which conditions it would germinate in an experiment. We'd use cotton wool and dampen it, and placing the seedlings at the bottom. Depending on which bottle it was, some were mixed with dampened cotton wool, and others didn't have cotton wool that were dampened. Then the opening of the bottle was covered, except for one which was covered with a lid. (See the picture). Now, I have to explain my results in my lab report. I can't find a solid source on what factors that cause the germination of seedlings. I've covered cellular respiration, and photosynthesis, but I don't know how to proceed from here. Bear also in mind that there's no soil in which the seed is germinating, so I will have to be able to explain this. Second of all, could you clue me in on how moisture is important for the germination of seedlings? Should I also bring up the physiology of seedlings and how they're growing?

1) Does the three t-tests support the hypothesis: of manipulating light exposure will influence the flowering time of Brassica rapa plants by using light from the sun and using incandescent bulbs, or not? If it did not support the hypothesis, then what changes would you make? 2) Do these three t-tests have different growth rates? 3) Is there anything to learn about this study of the graphs and t-tests?
