Complete the table below based about the alternation of generation of land plants based on the photo:
Ans. THE GIVEN HERE IS THE LIFE CYCLE OF AN ORGANISM THAT UNDERGOES THE HAPLO-DIPLONTIC LIFE CYCLE.
1. SPOROPHYTE;- Diploid and multicellular.
2. SPORE;- Haploid and unicellular or 1 celled.
3. MALE GAMETOPHYTE;- Haploid and multicellular.

5.GAMETES;- Haploid and 1 celled or unicellular.
6.ZYGOTES;- Diploid and 1 celled or unicellular.
7. SEED ;- Diploid and multicellular.

draw a diagram the parts of alternation of generation; plant stages (gametophyte & sporophyte), diploid, haploid, mitosis, meiosis, spore and gamete release, fertilization
BIOL 1020 Homework Evolution & Natural Selection 4 NATURAL SELECTION: 1. In your OWN words, explain what natural selection is. What is required? What is the result? 2. True or false? For natural selection to work, a population must have genetic variation. Explain your answer. 3. List three sources of genetic variation in a population. Identify which sources are most important for asexually reproducing organisms. Which method is most important for sexually reproducing organisms? 4. List three mechanisms which cause...
In the alternation of generations lifecycle in plants... A. There is a diploid multicellular phase (sporophyte) and haploid multicellular phase (gametophyte) The zygote undergoes mitosis to form a multicellular embryo. Meiosis and syngamy both occur.
Sketch the lifecycle of a bryophyte (alternation of generations). Place the following labels on the sketch: sporophyte, gametophyte, gametes, spores, mitosis, meiosis, diploid, haploid, fertilization, zygote. Sporophytes are attached to which sex gametophyte? _______________________ Are spores haploid or diploid? ______________________ Which life form, gametophyte or sporophyte, undergoes meiosis? ______________________ In mosses (and all bryophytes), which is the dominant life form, sporophyte or gametophyte? ____________________ A) Is the gametophyte of the fern directly protected by the sporophyte? B) Where could you...

Adult Mitosis Zygote 2N Fertilization Meiosis Spores Eggs Sperm Adult Mitosis 11. Describe two ways that plants affect the global water cycle: 10. Below is a diagram of the alternation of generations life cycle a) Add sporophyte and gametophyte to this diagram (label the adult forms).

Describe the complete life cycle of non vascular plants (Bryophyta) and explain the process of alternation of generation in their sexual reproduction.Include but not limited to; gametophyte, sporophyte, zygote formation, diploid and haploid stages, and spore formation.
51 Review questions: 1. Does the thallus contain vascular tisues? 2. 1s the thallus the gametophyte or the sporophyte generation? 3. Where are the rhizoids located and what is their function? 4. Where is the pore located and what is its function? (similar to stoma in higher plants) 5. Is the gemmae cup a sexual or asexual reproductive structure? 6. Are gemmae haploid or diploid?_ 7. When rain splashes the gemmae out of the cup, what do they grow into?...
Which of the following is/are HAPLOID (1N) in the alternation of generations lifecycle in plants? A Zygote B. Spores Sporophyte D. Gametes
