Seed Germination- Growing Lentils

On July 5th we prepared a flask with cotton , a piece of paper and 4 seeds. They had been soacked in water the previous night. We worked in pairs, studying variables (temperature, water, sunlight, covered and uncovered flasks)

I worked with Azul and Nina and the variable we studied was water.

Here you can take a look on my germinated seeds on day 11

This is the table of results I have been completing day by day sbout the germination of my seeds.

My seed had all the variables, which is not the case of Azul, a member of the group, who studied the growth of her seed without water. I watered my plant everyday when needed and I realized that if the cotton was still wet, I should not water it yet. On the weekends, my seed was not watered but luckily the cotton kept my seed wet for those days.

The 75% of my seeds germinated. (3/4)

Seeds without water | results

None of the seeds grew (0%)  and instead they went black. They were dry and harsh.

Azul provided the seed sun, good temperature, oxygen, and an uncovered flask)

Conclusion: After comparing the results that my partner who did not water the seed and my results, I got to the conclusion that seeds without water can not germinate and can not get out of their dormancy, they stay dormant all the time. A seed needs water to grow, and that is obligatory.







Seed Germination

In Biology class, after revising seed germination  we had to answer the two questions of the activity 3 of page 210

i) The age of seeds to make a fair test, if not you would not know if the results are different because of the age of the seed or because of the different conditions.

ii) Room temperature and the presence of water.

Then, we had to make this test on seed germination with Nina we got 10/10

Here you can take the test too
