Select the correct statement describing the life cycle of angiosperms. a. double fertilization in the life cycle of seed plants results in the production of a diploid zygote and a triploid endosperm nucleus. b. the life cycle of seed plants does not include a gametophyte generation. c. in angiosperm life cycles, the female gametophyte is the ovule.

A. Double fertilization in the life cycle of seed plants results in the production of a diploid zygote and a triploid endosperm nucleus.

Explanation:

Many angiosperms have central cell which contains two haploid nuclei. These fuse before or during fertilization. The fusion of this homodiploid nucleus (diploid zygote) with the sperm nucleus gives rise to a triploid endosperm nucleus that has two maternal and one paternal genetic make-up.

b.

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
