"Seed Germination Experiment (2)" Biology and Environment PPT Download
Part 1: Importing new lessons
Have all the mung bean seeds we planted sprouted? What about mung bean seeds from other groups? Today we will study further.
Seed Germination Experiment PPT, Part 2 Content: New Lesson Learning
Our "Seed Germination" Experimental Program
Questions we ask
Is water necessary for mung bean seeds to germinate?
Our speculation
Mung bean seeds need water to germinate.
Same conditions for both groups
Temperature, air, and three mung bean seeds of the same size each.
Different conditions for the two groups
water
Experimental method
Let one group of seeds get water and keep them moist, which is called the experimental group; let the other group of seeds get no water and keep them dry, which is called the control group. This experiment must be conducted simultaneously by at least two groups.
Seed germination experiment PPT, part three: conclusion summary
Conditions for seed germination:
One is temperature. The lowest temperature for seed germination is 6-7°C, and normal germination can occur at 12-14°C. The optimal temperature is 20-25°C, and the highest is 35°C.
The second is moisture. Generally, it needs to absorb 120-140% of the water equivalent to the dry weight of the seed itself to germinate.
The third is sufficient oxygen.
Seed Germination Experiment PPT, Part 4: Classroom Exercises
(1) Fill in the blanks
1. The minimum temperature for seed germination is ( ) ℃, and ( ) ℃ can germinate normally. The optimal temperature is ( ) ℃, and the maximum temperature is ( ) ℃.
2. Seeds generally need to absorb ( ) water equivalent to the dry weight of the seed itself to germinate.
3. Seed germination requires sufficient ( ).
(2) Judgment questions
1. There are no plants in Antarctica on Earth because it is very cold there all year round, and plant seeds cannot germinate and grow even if they arrive there. ( )
2. Wheat seeds begin to germinate and grow after being sown in the field. Therefore, wheat seeds cannot germinate without the soil. ( )
