Organism that can photosynthesise are called autotrophs or “self-feeders”. Chlorophyll in leaves enables plants to trap light energy; it traps sunlight energy for the plants and begins the process of photosynthesis. It gives plants the greenish colour that mo st plants contain. It also helps to make food for the plants. Hypothesis: Is the lack of chlorophyll due to the plants genotype or phenotype to the environment? Materials Used: •400 mustard seeds •cotton wool •2 plates Methods Used: •Took 400 mustard seeds Distribute it equally into two piles (200 seeds per pile) •Put one set of seeds in cotton wool (200) and the other set of 200 seeds in another piece of cotton wool. •Take the two cotton wools and place each one on a separate plate. •Put one plate in the sunlight •Put another plate in a dark cupboard. •Water the seeds daily and record the results that are viewed. Data was collected on annual recording of the plants growth and change in colour. I then recorded the plant growth and colour change on a line graph Plant Growth (sunlight)Chlorophyll change (sunlight)Plant Growth (dark upboard)Chlorophyll change (dark cupboard) Day 1 Day 2 Day 3 1. 40. 4 Day 40. 1320. 7 Day 50. 133. 50. 8 Day 60. 1542. 30. 02 Day 70. 174. 32. 80. 04 Day 80. 245. 23. 40. 04 Day 90. 265. 83. 80. 06 Day 100. 266. 44. 20. 07 It has concluded that my hypothesis was correct. The presence of chlorophyll does effect the phenotype of the plant. Chlorophyll adds the green pigment to plants. As seen in the investigation, chlorophyll reacts more towards plants that were placed in an environment where there is a lot of sunlight in comparison to an environment that contains no sunlight (dark cupboard).
The Essay on Seed And Gardenia
Vascular or nonvascular? My plant is vascular because it has true roots, stems, and leaves. It has a system for transporting food and water. My plant has tube –like structures that provide support and circulate water and food throughout the plant. Monocot or Dicot? My plant is a dicot because it’s flowers have either four or five petals or multiples of these numbers. The leaves are wide with ...
After completing a daily record of the chlorophyll and plant growth, we can conclude that when in sunlight, chlorophyll reacts very fast and plant gets excessively green, however, the plant growth does not grow at a high extent or very fast. Whereas in a dark area, chlorophyll hardly reacted at all resulting in the growth not being green, the growth of the plant was much faster than that in the sunlight. As a result in sunlight chlorophyll worked faster than in the dark and in the dark the plant grew faster compared to that plant in the sunlight.
