What do seeds contain?
| A. mature sporophyte and nutritive tissue |
| B. female gametophyte, embryo, and nutritive tissue |
| C. female gametophyte and nutritive tissue |
| D. male gametophyte and nutritive tissue |
| E. only embryo |
Homework Answers
Answer- A. Mature sporophyte and nutritive tissue
Explanation-
1. Seed contains seed coat, endosperm and embryo.
2. The seed coat is made from diploid tissue from diploid parent plant.
3. Endosperm is nutritive tissue present in seed that is mostly triploid. In endospermic seed, endosperm surrounds the embryo and provides nutrition to developing embryo by providing starch mainly and it also contains oil and proteins.
4. Embryo is mature sporophyte. When Male gamete (haploid sperm) and female gamete (haploid egg) fuses it produces zygote and then zygote develops into multicellular sporophyte.
5. So that seed contains mature sporophyte and nutritive tissue. Male and female gametophyte are present in flower.

In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
