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

1.	List the charges that occur when an ovule matures into seed.
Answer» `" "`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 mosisture by mass). `" "`The general metabolic activity of the embryo slows down. `" "`The embryo may enter a state of inactivity called dormancy.
