Four stages in growth are (in order):

- Germination - Growth - Maturation - Death

1. running down 2. youthful tissue (keeps growing) 3. food supply, part of the embryo seed plant 4. maturates, develops specialized function 5. food supply, not part of the embryo seed plant 6. grass 7. xylem 8. plant that grows and dies in a year 9. organic catalyst, helps to cause other reactions 10. bean

1. entropy 2. meristem 3. cotyledon 4. differentiate 5. endosperm 6. monocot 7. wood 8. annual 9. enzyme 10. dicot
