After fertilization, the ovary thickens and forms a fruit. d. The gametophyte is longest phase of the life cycle.During the process of double fertilization, the pollen tube grows into the ovule through an opening called the pollen tube enters a cell, which will degenerate and release two sperm. oooo synergid, micropyle micropyle, endosperm micropyle, synergid synergid, endosperm From there, theIn the mature angiosperm seed, the nutritive tissue is triploid. This tissue is formed from; Two polar nucleii fusing with a sperm cell The synergids fusing with a sperm cell The sperm fusing with the egg cell The embryo
- Choose the one answer that fits best. Which of the following statements regarding seed germination is NOT correct? O a. The first structure to emerge is the root O b. The root grows away from the light or down O c. Seeds can always germinate no matter what temperature and light conditions are d. There is no photosynthesis until green leaves emerge e.
