Work done = Force x _________

Which of the following is the most effective example of work?

What is the product of force and displacement?

What is the unit of mass?

Force is a _____ or _______

Under the favorable conditions of light, temperature and water the ____________ begins.

 

• Every seed has specific conditions for it's germination.
• Some seeds need low temperature to germinate like wheat while some seeds need high temperature to germinate like cotton.

Seed germination is slowed, and ___________ development begins when the temperature falls below a moderate level.

• Low temperature can damage seeds and Stop their germination by development of fungus in them .

______________ aids in seed rupturing and transforms insoluble food into soluble form for transfer to the embryo.

• Water enters in seed cells through imbibition.
• It causes rupturing of seed coat by making it swollen and soft .

During ________________, the water and gas-resistant seed coat inhibits water intake and oxygen exchange.

• During seed dormancy seed coat prevents it from the harsh conditions.
• A seed doesn't germinate untill it doesn't get the suitable conditions for germination.

___________________ is an evolutionary adaptation or a situation in which seeds are unable to germinate even in ideal conditions.

• The phase in which a seed can't germinate is known as seed dormancy.

Plant growth regulators are found in some seeds, and they prevent __________.

• Some hormones like abscisic acid and gibberellic acid are present in some seeds which regulates seed germination and plant growth.

Some seeds do not need light for germination.

• Some seeds don't need light for germination as every seed has it's own suitable conditions to germinate for temprature,light and water.

If there is enough temperature but no water for the seed, then still the seed will be able to germinate

• If there is only one condition is not applicable, the seed will not germinate.

Germination can sometimes come to a halt when the temperature rises above a certain point.

• A seed can't germinate in harsh conditions.
• A specific range of temperature should be there for seed germination.

Pick the odd one out.

• Plumule makes shoot system.
• Leaves are also a part of shoots.

Match the following:

1. Temperature                                                    a. Hydration
2. Light                                                                 b. 25 to 30 ℃
3. Oxygen                                                             c. Sunshine
4. Water                                                                d.  Aerobic respiration

• Water, oxygen, temperature and light , all the four things are important in germination of seed.
