Chapter 22, Problem 2CT
Summary Introduction
To explain: The reason behind the recessive mutation would be more likely to persist in a plant with a sporophyte-dominated life cycle, such as a fern, than in a moss.
Introduction: The plants are multicellular, photosynthetic eukaryotes on land. They are close to green algae, as they have cellulosic cell walls, chloroplasts, and store starch. They have alternation of generations, that is, a haploid generation (gametophyte) alternates with a diploid generation (sporophyte). Double fertilization is the process of formation of a zygote and the endosperm in flowering plants. It occurs when a pollen tube releases two sperm cells in the ovule. One sperm cell fuses with the egg cell to form an embryo and the other sperm cell fuses with two polar bodies to form an endosperm.

In most parts of the world, commercial potato crops are produced asexually by planting tubers. However, in some regions of the world, such as Southeast Asia and the Andes, some potatoes are grown from true seeds. Discuss the advantages and disadvantages of growing potatoes from true seed.
Please answer question 15
There are two alternative hypotheses about the life cycle of the early vascular plants, the transformation hypothesis and the interpolation hypothesis. If Rhynia and Sciadophyton are the two generations of one species, which hypothesis would be favored? Briefly describe the other hypothesis.

- no need to explain just need to know if its a,b c, or d 1.) Alternation of generation refers to the alternation of diploid and haploid generation. What is the difference between the alternation of generation in moss and pine? a.) In moss, gametophyte is dominant; whereas, in pine, sporophyte is dominant. b.) In moss, sporophyte is dominant; whereas, in pine, gametophyte is dominant. c.) In moss, gametophyte is dependent on sporophyte; whereas, in pine, sporophyte is dependent on gametophyte. d.) In moss, meiosis occurs during gamete formation; whereas, in pine, it occurs in zygote formation. 2.) Meiosis involves two phases, meiosis I and meiosis II. This type of cell division occurs during the formation of both sperm and ovum. The first meiotic division of the primary spermatocyte results in two secondary spermatocytes. .What is the result of the first meiotic division of the primary oocyte? a.) two secondary oocytes b.) two polar bodies c.) two ovum d.) one secondary oocyte and…arrow_forwardWhat would happen to a plant that had a mutation preventing it from being able to perform phototropism?

The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forward
