Question

List the changes that occur when an ovule matures into seed.

Answer 1

• Integuments of ovules harden as tough protective seed coats
• The micropyle remains as a small pore in the seed coat
• As the seed matures, its water content is reduced
• Seeds become relatively dry (10-15 per cent moisture by mass).
• The general metabolic activity of the embryo slows down.
• The embryo may enter a state of inactivity called dormancy
