Question

Skulls Worksheet Hs 3.28 Active Reading Section: Multicellular Life Cycles Read the passage below. Then answer the questions that folow. Most animals, such as humans, have a diploid life cycle. Most of the life cycle is spent as a diploid organism. For example, humans have 46 chromosomes in their diploid cells. We peoduce gametes (eggs or sperm) with 23 chromosomes that are haploid through the process of meiosis. Two gametes fuse during fertilization so form the diploid zygote. The rygote then undergoes mitosis to produce a multicellular offspring. The haploid life cycle is common in fungi and some protists Most of the life cycle is spent as a haploid organism. Before melosis, the organism is a diploid zygote. After the zygote goes through meiosis, it develops into four haploid cells. The four ceills then go through mitosis and each becomes a malticellular haploid individual. The individual can produce gametes through mitosis. The gametes then fuse to become the diploid zygote. The process repeats again SKILL: READING EFFECTIVELY In the space provided, match each statement with the life cycle it describes. Write d if the statement a describes a diploid life eycle, write h it it describes a haploid life cyele, or write b if it describes both 1. The haploid stage is most predominant. 2. Diploid and haploid stages are presemt 3. Diploid cells divide by mitosis. 4. Haploid cells divide by mitosis. 5. The diploid stage is common -6. Most animals have this life cycle. An analogy is a comparison. In the space provided, write the letter of the term or phrase that best completes the analogy 7. Haploid cell is to diploid cell plate as egg is to a·gamete. b. individual. c. zygote. d. Both (a) and (b) Meiosis and Sexual Hot Biology
