I need some help here. Can seeds germinate when placed on a moist cotton wool in the refrigerator?

In this case, water and air is given except warmth.
Thanks.

If i didn't remember wrongly, i think nope. I think this was a popular example used in pri sch for \"experimenting\".

Hi underthesea, I found out that for the coffee question, the water would collect on the coffee and it would become moist... Hope that helps!

Hi

In primary science, students are taught that the right conditions for germination are water, air and warmth. Therefore seeds will not germinate in a refrigerator.

Thanks to those who have helped and replied. I think OVERALL: warmth is needed though some seeds can germinate even in cold temperatures.

Now the next questions: is light necessary during germination? Ths \"ans\" is not necessary ie seeds can germinate even in the darkness provided water and air is provided because they get their food from their seed leaves. Until the food in the seed leaves has been used up, by then the green leaves are grown, the seedlings would need light ie sunlight to make its own food during the day.

Doesn't light equate to warmth?

I am getting more and more confused.

Thanks.

Hi


Question on germination in primary science usually centre on the three conditions, warmth, air and water. They are usually not too difficult to handle.

Examples are test tubes containing seeds placed in moist cotton wool, dark cabinets or refrigerator. Sunlight is not needed for germination. Seeds can germinate at room temperature. I suggest you look at some of the past years papers for examples.

Let our young ones take small steps at a time, arouse their curiosities but do not overload them too much.

light doesn’t equal warmth. You can have warmth for seeds without light.

Thanks coffeecat for all the help.

Hi hi,

I had the chance to go into a germination room.

It was almost totally dark, but slightly warm. In there, were shelves of trays. In the trays, were seeds to be germinated.

The guide explained that the seeds needed warmth to germinate, and thus the warmer-than-outside temperature.

It was there and then that it really impressed upon me that seeds do not need light to germinate.

Thanks.
