Renu soaked some moong seeds overnight in water. Next day, after draining out the water, she wrapped the seeds in a wet cloth. After a day, she observed small white structures growing out of the seeds. These small white structures will develop into

  1. Stems

  2. Roots

  3. Leaves

  4. Flowers

Show answer
Correct Option: B
Explanation:

Sprouts develop in the pulses or grain under humid environment with adequate amount of water fasten the process of germination and Roots comes out.

So the correct option is 'Roots'.

Which of the following is a step which is involved in seed germination?

  1. Absorption of Water

  2. Absorption of Carbon Dioxide

  3. Absorption of Light

  4. All the above

Show answer
Correct Option: A
Explanation:

Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow.

  1.  When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth. 
  2.  The seed grows a root to access water underground. 
  3. The shoot appears above ground. 

The seed sends a shoot towards the surface, where it will grow leaves to make food that provides energy. 
The leaves continue to grow towards the light source in a process called photomorphogenesis.
So the correct option is 'Absorption of Water'

State whether the following statements are true or false.
Oxygen is not necessary for seed germination;

evs developmental journey of seed seed to plants germination of seeds life within the seed introduction to plant organs and germination

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Aerobic respiration is respiration which occurs in the presence of oxygen. Aeration is the main phenomenon which helps in the germination of seed. Oxygen is absorbed by the cells which later gets transformed into energy for future uses. For better germination of seeds require oxygen, water, sunlight, and temperature.

So, the correct statement is 'True'.

Choose the correct answer from the alternatives given.
Seed germination is over when the:

  1. embryo sporophyte absorbs water

  2. embryo sporophyte resumes growth

  3. primary root pokes out of the seed coat

  4. cotyledons unfurl

Show answer
Correct Option: C
Explanation:

In summary, seed germination is the process of a fertilized plant ovary, or seed, developing into a mature plant. Seed germination starts with imbibition when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water.

So, the correct option is 'primary root pokes out of the seed coat'.
