Concept explainers
To determine:
The similarities and differences between the spores of ferns and the seeds of higher plants.
Introduction:
Ferns are seedless vascular plants, which are reproduced by the production of several types of spores. They do not make fruits, and live in a dark and moist climate. Ferns are examples of
To determine:
The proportion of fern spores that would be likely to survive long enough for the reproduction.
Introduction:
Ferns belong to the category of seedless vascular plants and are able to undergo the process of reproduction by the production of several types of spores. They are unable to make fruits, and live in dark and moist climate of colder regions. Ferns are examples of pteridophytes.
To determine:
The factors that decide whether a spore will produce a new fern plant.
Introduction:
The members of ferns are reproduced by various types of spores and possess vascular system. They do not make fruits, and live in a dark and moist climate. Ferns are examples of pteridophytes.

BIOLOGY:THE ESSENTIALS (LL) W/CONNECT
- In embryophytes, especially spermatophya, what is the difference between a "sporocyte" (e.g., megasporocyte) and the actual spore (e.g., megaspore)? a) Meiosis: Megasporocyte is still diploid, megaspore haploid b) Mitosis, number of nuclei: Megaspore has eight cell nuclei, megasporocyte only one c) Cytokinesis: Megasporocyte has only one cell, Megaspore can have several (as endosporic gametophyte). d) None: the two terms are synonymous. e) Meiosis: Megaspore is still diploid, megasporocyte haploidarrow_forwardWhen the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parental hyphae. What is the BEST explanation for this observation? A. The spores inherit half their genes from each parent. B. The spores inherit haploid nuclei from their parents. C. The spores inherit mutations as a result of meiosis. D. The spores inherit mutations as a result of mitosis.arrow_forwardWhich of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.arrow_forward
- Indicate the ploidy number for each of the following cells indicated on the life cycle diagram above. Haploid = 1 and Diploid = 2. zygote Answer basidiospores Answer basidium with four nuclei Answer mycelia Answerarrow_forwardAre fern spores haploid or diploid? Are the spores proudced by meiosis or mitosis? Where are the spores produced?arrow_forwardIndicate the ploidy number for each of the following cells indicated on the life cycle diagram above.

- When and where does reduction division take place in the live cycle of a livewort, a moss,a fern?arrow_forwardWhen the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true? A. The trait for spore color is determined by exactly one gene. B. The trait for spore color is determined by more than one gene. C. The allele for black spores is dominant over that for white spores. D. The allele for white spores is dominant over that for black spores.arrow_forwardIn a population of bread molds (zygomycetes), one individual inherits a mutation that prohibits it from engaging in plasmogamy with other individuals. This fungus will not be able to do which of the following two things; *** 'Bubble both that apply*** Note that both are required for credit. The fungus will not be able to reproduce sexually The fungus will not be able to create spores of any kind The fungus will not be able to digest any food The fungus will not fuse it's cytoplasm with another individualarrow_forward
