Homework Answers
gametophyte form in archegonia(egg are formed) and antheridia(sperm are formed in this)
Spore are formed in sporophyte which are further locate in sporangia.
Sporangium are of 2 type-microsporangia in which microspore form and megasporangia in which megaspore are formed.
In short --Sporophyte form -spores which form-gametophyte which form gamete
Sporophyte are located in sporangia.

ving questions about ferns: 1. Are the spores produced by the fern sporophyte formed by mitosis or meiosis? 2. Do the spores belong to the gametophyte or the sporophyte generation? 3. Are the gametes produced by mitosis or meiosis? 4. Are the archegonia and antheridia haploid or diploid? (HINT: Think about which generation produces them) 5. Is the dominant generation for the fern the gametophyte or the sporophyte? 6. Can you suggest an ecological role for ferns?

What is true about the life cycle of a land plant? 1. The gametophyte produces spores by meiosis. 2. The life cycle is entirely haploid, so the sporophyte phase does not exist. 3. The sporophyte produces spores by mitosis. 4. The sporophyte produces spores by meiosis. 5. The gametophyte produces gametes by meiosis.

Label the figure below to describe the life cycle of a flowering plant. Sporophyte produces spores through meiosis Megaspores become embryo sacs Mature ovary becomes a fruit MEIOSIS FERTILIZATION diploid (2n) haploid (n) Double fertilization produces zygote and 3n endosperm nucleus Microspore becomes pollen grains Ovule becomes seed and endosperm is taken up by cotyledons

Plant Diversity The scales of the female cones bear ovules, which enclose the female sporangia. Cells in the female sporangia also undergo meiosis to produce spores. One of the spores from each meiotic division develops into a female gametophyte by mitosis. As the pollen germinates and produces sperm nuclei by mitosis, the female gametophyte produces an egg. One sperm nucleus reaches the egg through the pollen tube and fertilizes it. Notice in Figure 6 that the male gametangium has been...

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...
