Term
Gymnosperms: Difference between pollination and fertilization
Definition
wind disperses pollen to ovulate female; pollen tube penetrates the ovule & releases sperm

Gymnosperms: Life cycle description
Definition
disperse seeds, male pollen penetrates egg, seeds travel by wind and create offspring
