Give the possible genotypes and ploidy of the reproductive parts listed below if a pine tree with female megasporophylls have a genotype "aa" is cross pollinated by a male plant with cones which have microsporophylls with a genotype "Aa". These plants are usually dioecious.
microspore mother cell -
megaspore-
cells of cotyledon from resulting embryo after fertilization-
cells of the integument-
archegonia cells -
pollen grain cells-
sperm-
seed coat -
megagametophyte -
ovule and integuments-
Do these plants exhibit double fertilization?
Do these plants produce a fruit?
Do these plants have an ovary?
