Question

Сергей решил выяснить роль одного из таких условий,проведя следующий опыт.он взял два одинаковых стакана, в которых было немного воды, положил в каждый по 15 семян горох, причём в один он насыпал немного почвы.оба стакана он оставил в классе на столе учителя. вскоре он обнаружил, что в обоих стаканах семён проросли.ответ на какой вопрос мог получить сергей при постановке своего опыта? 1 как влияет на прорастание семян гороха присутсвие в кабинете школьников? 2 необходим ли для прорастания семян гороха солнечный свет? 3 прорастают ли семена гороха в стеклянной посуде? 4 зависит ли прорастание семян гороха от наличия почвы?

Answer 1

Сергей получил ответ на вопрос 4: зависит ли прорастание семян гороха от наличия почвы.

Answer 2

4 потому что и в почве и в воде семяна прорастают одинаково

Answer 3

The Experiment and Sergey's Question

Sergey conducted an experiment where he took two identical glasses with a small amount of water and placed 15 pea seeds in each glass. In one glass, he added a little bit of soil. He left both glasses on the teacher's desk in the classroom. After some time, Sergey noticed that the seeds in both glasses had sprouted. Based on this experiment, Sergey could have asked the following question:

What effect does the presence of soil have on the germination of pea seeds?

Answering Sergey's Question

The presence of soil in one of the glasses in Sergey's experiment could have led him to question whether the seeds require soil for germination. To answer Sergey's question, we can refer to the following information:

According to a search result snippet seeds generally require certain conditions for germination, including moisture, oxygen, and suitable temperature. Soil provides a favorable environment for seed germination by providing moisture, nutrients, and support for the developing seedling.

However, it is important to note that not all seeds require soil for germination. Some seeds, such as certain types of orchids, can germinate without soil and rely on other mediums like air or water.

Therefore, the answer to Sergey's question would be:

The presence of soil can facilitate the germination of pea seeds by providing a suitable environment with moisture, nutrients, and support for the developing seedling. However, not all seeds require soil for germination.

Additional Information

It's worth mentioning that light is another important factor that can influence seed germination. Some seeds require exposure to light for germination, while others prefer darkness. In Sergey's experiment, since both glasses were kept in the classroom, it can be assumed that the seeds were not exposed to direct sunlight. However, this experiment does not provide information about the role of light in the germination of pea seeds.

If Sergey wanted to investigate the role of sunlight in seed germination, he could have set up another experiment with one glass placed in a well-lit area and another glass kept in a dark place. This would allow him to observe the difference in germination rates between the two conditions.

Conclusion

In conclusion, Sergey's experiment with two glasses containing pea seeds, one with soil and one without, allowed him to observe that both sets of seeds sprouted. This led him to question the role of soil in seed germination. While soil can provide a favorable environment for seed germination by offering moisture, nutrients, and support, not all seeds require soil for germination. Other factors, such as light, also play a significant role in the germination process.
