Concept explainers
(A)
To identify:
Whether sporophyte is haploid or diploid structure.
Introduction:
The haploid structures are those that contain‘n’ set of chromosome and the diploid structures are those which contain ‘2n’ set of chromosome.
(B)
To identify:
Whether spore is haploid or diploid structure.
Introduction:
The haploid structures are those that contain‘n’ set of chromosome and the diploid structures are those which contain ‘2n’ set of chromosome.
(C)
To identify:
Whether gametophyte is haploid or diploid structure.
Introduction:
The haploid structures are those that contain‘n’ set of chromosome and the diploid structures are those which contain ‘2n’ set of chromosome.
(D)
To identify:
Whether zygote is haploid or diploid structure.
Introduction:
The haploid structures are those that contain‘n’ set of chromosome and the diploid structures are those which contain ‘2n’ set of chromosome.

- Identify each of the following structures as haploid or diploid.(A) sporophyte(B) spore(C) gametophyte(D) zygotearrow_forwardFungi would best be described as having which of the following life cycles? A. diploid-dominant B. alternation of generations C. gametophyte dominant D. haploid-dominantarrow_forwardMarchantia is specifically considered a Liverwort, which are classified under the larger group known as [A]. The structures in the pictures are gametophytes. Provide the sex and specific term used to describe the structure on the left side [B] and on the right side is a/an [C].arrow_forward
- 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_forwardWhat is a sporophyte? A diploid plant that undergoes meiosis A haploid plant that produces gametes via meiosis A diploid plant that produces gametes via mitosis A haploid plant that undergoes mitosisarrow_forwardThe megaspore in most flowering plants grows into a megagametophyte that has seven cells and eight nuclei. Name and describe the seven cells.arrow_forward
- What is the ploidy of the most conspicuous form of most fungi? a. diploid b. haploid c. alternation of generations d. asexualarrow_forwardLabel the diagram which features an illustration of a portion of the sporophyte of Selaginella with strobili, and a photomicrograph of the longitudinal section of a mature strobilus. Indicate whether each of the structure you identified is haploid (n) or diploid (2n)arrow_forwardBasidiomycota is a division of the Kingdom Fungi. They include groups such as mushrooms, and reproduce sexually through the formation of cells called basidia. Which of the following rows identifies Process 1 and Process 3 in the life cycle shown in the diagram? Select one: a. Process 1 Process 3 Meiosis Mitosis b. Process 1 Process 3 Mitosis Mitosis c. Process 1 Process 3 Meiosis Meiosis d. Process 1 Process 3 Mitosis Meiosisarrow_forward
- Please Aspaarrow_forwardKey features of seed plants facilitating life on land include three of the following four traits. Which of these is an exception? a. Reduced gametophytes b. Pollen c. Homospory d. Seeds Which of these will most likely happen when bryophyte spores are dispersed to a favorable habitat, such as a moist soil or tree bark? a. They will germinate and grow into sporophytes. b. They will germinate and grow into haplophytes. c. They will germinate and grow into chlorophytes. d. They will germinate and grow into gametophytes. Which of the following is the purpose of having cuticles only at the upper surface of thallus of a non-vascular plant like a moss? a. Direct water and nutrient absorption b. Efficient exchange of gases c. Faster generation of osmotic pressure in leptoids d. Easier diffusion of carbon dioxidearrow_forwardDetermine whether the structure in the life cycle of a moss is haploid or diploid and determine the process used to make the structure. 1 - Haploid 2 - Diploid A - Mitosis B - Meiosis C - Fertilization Gametophyte Answer Answer Sporophyte Answer Answer Spore Answer Answer Zygote Answer Answer Egg Answer Answerarrow_forward
