Pollen grains stick to the seed cones. A [9]__________ grows from the pollen grains into egg cells in the cone. A [10]__________ enters an egg cell and fertilizes the egg and later form a zygote. The [11]__________undergoes cell division that results in the information of an embryo. As the embryo develops ,the outside layer of the ovule forms a [12]__________.Seed development can take as long as three years. When seed[13]____________ the female cone[14]_________and releases them. A seed that lands in a place with enough water, soil and sunlight can grow into a[15]__________.
