What happens after the root (radicle) emerges during germination?

Define/ Explain the following.
Germination

Most of the seeds germinate under dark conditions.

Arun germinated some seeds. He measured the height of one of the seedlings every two days. He wrote down its measurements.

Day $2: 10 \mathrm{mm}$, Day $4: 15 \mathrm{mm}$, Day $6: 25 \mathrm{mm}$, Day $8: 35 \mathrm{mm}$, Day $10: 40 \mathrm{mm}$

Draw a line graph of Arun's results.

Present Arun's results in a table. Remember to give each column a heading.

Observe the bar graph carefully to answer the question.

Class $5$ investigated germination. They put seeds on damp cotton wool and placed them into plastic bags. They then put the plastic bags in different places. They checked the seeds after three days. This is the bar chart of their result.

Suggest a reason why the same number of seeds germinated in the desk drawer and on the top of the desk?

What do the result tell you about the condition that seeds need to germinate?
