Germination is the ..................... of a seed into a/an ....................
development .... building
development .... seedling
changes .... adult plant
changes .... mature plant
Germination of seeds only occurs when the conditions are right.
What are these conditions?
air, water and soil
air, water and light
water, oxygen and warmth
warmth, water and carbon dioxide
Based on the diagram above, which seeds will not germinate?
A
B and C
B, C and D
All of the above
An experiment has been conducted by Ahmed. He wants to find out the factors of germination.
After 5 days, he observed that seeds in B does not germinate.
Explain why is this so?
this is because water is present
this is because water is absent
this is because the temperature is too cold
this is because the temperature is too hot
Choose the BEST statement on why water is needed in the germination of seeds.
water is to soften the seed coat
water is to soften the seed leaves
water is needed for the plant to grow
water is needed by the roots
Sheila wants to investigate whether water is needed for germination. She set-ups an experiment as shown above. She used 5 seeds for each tube and placed both at the room temperature. After 5 days, she noticed that only seeds in tube A germinate.
Based on that, indicate the constant variables in her experiment.
the presence of water
the number of seeds
the temperature
the number of seeds and the temperature
From the experiment above, it is found that only seeds in A germinated.
Explain, why this is so?
seeds A have water and warmth.
seeds A have water, warmth and carbon dioxide.
seeds A have moist cotton and warm temperature.
seeds A have water, warmth and oxygen.
From the experiment above, it is found that seeds in B did not germinate.
Explain, why this is so?
seeds B do not have oxygen
seeds B do not have water
seeds B do not have suitable heat
seeds B do not have oxygen, water and it is cold
From the experiment above, it is found that only seeds in A germinated.
Explain, why seeds in C did not germinate?
seeds C do not have oxygen
seeds C do not have carbon dioxide
seeds C do not have light
seeds C do not have water
From the experiment above, it is found that only seeds in A germinated.
Explain, why seeds in D did not germinate?
seeds D do not have oxygen
seeds D do not have water
seeds D do not have suitable heat
seeds D have oil
