EXPERIMENT ON EFFECT OF TEMPERATURE ON THE GROWTH OF GERMINATING SEEDS AND BRINE SHRIMPS.
Aim: to investigate the effect of difference in temperature on the growth of germinating seeds and hatching of brine shrimps eggs.
Introduction:
Growth is the process by which a plant increases in the number and size of leaves and stems. The growth of both plants and animals requires energy. Animals get their energy by digesting the plants they eat. Plants get their energy from the sun through photosynthesis. Photosynthesis is the process where the green pigment in the plant's …show more content…
While producing eggs under favorable conditions, some species or strains are viviparious (live birth) and some may reproduce via parthenogenesis. Brine shrimp eggs are metabolically inactive and can remain in total stasis for several years while in a dry, oxygen-free environment, even at temperatures below freezing. This characteristic is called cryptobiosis meaning "hidden life" (also called diapause). Once placed in water, the cyst-like eggs hatch within a few hours, and will grow to a mature length of around one centimeter on …show more content…
The growth of the seeds is observed 3 times a day for 3 days. 6. The condition of the seeds, the length of the plumule and radical are measured and the numbers of leaves are counted. 7. The results obtained are recorded in table.
B. The effect of temperature on the number of brine shrimps eggs hatched 1. 10g of sodium chloride is weighed by electronic weighing balance and placed into 1000ml of beaker. 2. 1000cm3 of mineral water is added into the beaker. 3. Steps 1 and 2 are repeated for 2 times. 4. Brine shrimp eggs are added into the three different beakers. 8. The beakers are placed at three different surrounding temperatures in which one is placed in the incubator (35˚C), the other one is placed in the air-conditioning room (20-22˚C) and the other one is placed in the room with the room temperature (25-27˚C). 5. The solution is stirred gently 2/3 times per day for 3 days. 6. Every day, a drop of the solution from each beaker is observed under the microscope and the numbers of eggs hatched are counted. 7. The result are recorded in table as shown below.
Results:
1. Seed germination
