Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation. g.

Which statement describes events leading to formation of offspring in the conifer life cycle? a) A diploid pollen grain produced by the male sporophyte enters the female sporophyte and fuses with a haploid megasporangium. b) A haploid sperm from pollen enters the female gametophyte and fuses with a haploid egg. c) A diploid sperm from pollen enters the female gametophyte and fuses with a diploid egg. d) A haploid pollen grain produced by the male sporophyte enters the female sporophyte and fuses with a haploid megasporangium.

How do the sporophyte and gametophyte generations compare in a conifer? a) The sporophyte generation is much smaller than the gametophyte generation and the two generations grow as independent structures. b) The sporophyte generation is much larger than the gametophyte generation and the two generations grow as independent structures. c) The sporophyte generation is much larger than the gametophyte generation and the two generations grow in a single individual. d) The sporophyte generation is much smaller than the gametophyte generation and the two generations grow in a single individual.

Vascular plants are divided into two main groups: seedless vascular plants, including ferns and club mosses; and seed plants. The seed plants are further divided into gymnosperms (seed plants that do not produce flowers) and angiosperms (seed plants that produce flowers).Indicate whether each description applies to a specific group of gymnosperms or to all gymnosperms. Drag each item to the appropriate bin.

Which of the following contains multiple gymnosperm ovules?a) megasporangiumb) megasporec) integumentd) ovulate cone

Answer each of the questions, and then enter the terms into the box indicated in order to construct a diagram of alternation of generations. 1. What generation means "spore- bearing plant" ? ______ (Box 1) 2. What generation means "gamete-bearing plant"?  ________ (Box 2) 3. What type of cell does the generation in box 1 give rise to? ______ (Box 3) 4. What two types of cells does the generation in box 2 give rise to? ________ (Box 4 or 5) and ____________ (Box 4 or 5) 5. The cells in boxes 3, 4, and 5 are reproductive cells that are all haploid. However, the cells in boxes 4 and 5 differ from the type of cell in box 3 because these cells have to come together during an event called______ (Box 6) in order to grow into a living organism. 6. When these cells do come together they form a ______ (Box 7), which has a _____ (Box 8) chromosome number. This marks the transition to the other generation because this grows into the generation you indicated in box 1.7. Since this generation came about through the union the cells in boxes 4 and 5, it must have a ______ (Box 9) chromosome number. 8. Since this generation gives rise to haploid reproductive cells you have already entered in box 3, it must do so through the cell division process of ____. (Box 10) 9. These reproductive cells, unlike those in boxes 4 and 5, do not need to unite in order to grow into the next generation. Given a habitat conducive to germination, they simply grow into the next generation through the cell division process of _______ (Box 11)10. Since the generation in box 2 arose through simple growth of a haploid cell, it must have a _________( (Box 12) chromosome number11. Since this generation gives rise to haploid cells in boxes 4 and 5, it must do so through the cell division process of __________ (Box 13).
