Explain how some plants have alterations in their metabolism to generate heat (Why would some plants produce heat? What process is altered? How does this affect overall plant metabolism?)

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?

What parts do all plants have, and what parts do only some plants have?

Let T : U ? V and S : V ? W be linear mappings. Prove:
(a) If S is injective, then Ker(ST ) = Ker T .
(b) If T is surjective, then Im(ST ) = Im S.
