- Yes, since bigger creatures reproduce sexually, whilst smaller ones reproduce asexually (asexual reproduction). The reason for this is that multicellular creatures reproduce sexually, whereas unicellular species reproduce asexually. No, because complex species such as starfish and plants employ asexual reproduction more frequently than simple organisms.
Which statement is true for all sexually reproducing plants and animals which?
Which of the following statements applies to all sexually reproducing plants and animals? Spores, which are haploid, develop into haploid gametophytes through the process of mitosis. Mitosis is used by the gametophyte to create eggs, which are also haploid. In both cases, haploid gametophytes are responsible for the production of gametes.
Which structures are haploid?
The male gametophyte and the female gametophyte are haploid structures, but the zygote, which is generated by the union of two male and two female gametophytes, is a diploid structure.
Do plants produce eggs and sperm through mitosis or meiosis?
Mitosis is the process through which gametophytes create gametes. In mammals, meiosis is responsible for the production of sperm and eggs; however, in plants, meiosis is responsible for the production of the gametophyte.
Are gametophytes haploid or diploid?
Regarding chromosomes, the gametophyte is haploid (has just one pair of chromosomes) while the sporophyte is diploid (has two sets of chromosomes) (has a double set).
When comparing the life cycle of angiosperms and mosses which statement is true of both?
Which of the following statements is true of both angiosperms and mosses when comparing their life cycles? Meiosis is the process through which spores are formed. Small and without petals, a flower is produced by a plant that blooms in the spring before it begins to generate leaves.
What is endosperm quizlet?
Endosperm. Most flowering plants create a tissue called endosperm in the seeds of their flowers around the time of fertilization. It forms a protective shell over the embryo and supplies nutrients in the form of starch, however it may also contain oils and proteins. The nucleus of the primary endosperm. The result of the merging of the masculine and female.
Which statement about the number of chromosomes in the cells and gametes is correct?
In humans, gametes are haploid cells that have 23 chromosomes, each of which is one of the chromosomal pairs that occur in diplod cells. In animals, gametes are haploid cells that contain 23 chromosomes.
Which of the following statements about the random joining of any male gamete with any female gamete in nature is true?
When two homologous chromosomes are found together, they include one paternal chromosome as well as one mother chromosome. If the following statement concerning the random merging of any male gamete with any female gamete in nature is correct, which of the following claims is false? It results in the creation of individuals who are genetically distinct.
Is a sperm cell haploid or diploid?
Diploid organisms are those that reproduce sexually (having two sets of chromosomes, one from each parent). In humans, only their egg and sperm cells are haploid.
How can mitosis and meiosis be applied to plants and animals?
Cells of eukaryotes, including those of mammals, plants, fungi, and protists, divide by one of two methods: mitosis or meiosis. In sexually reproducing organisms, cells that generate gametes (eggs or sperm) split through meiosis, creating four cells, each with half the amount of chromosomes contained by the parent cell.
Does mitosis occur in plants and animals?
Mitosis occurs in all eukaryotic cells and is a natural process (plants, animals, and fungi). Plant, animal, or fungal cell renewal and growth are all examples of the term “regeneration.” Mitosis is especially vital in organisms that reproduce asexually, as it is the only means for these cells to proliferate in the absence of sexual reproduction.
Does meiosis occur in plants and animals?
The process of meiosis, which results in the formation of gametes, is used in sexual reproduction. These are sperm and eggs (ova) in mammals, and pollen and ova in plants. Meiosis is a process that occurs in both the male and female reproductive organs of the body.
What is a sporophyte and gametophyte in flowering plants?
The multicellular diploid plant structure is termed the sporophyte, which generates spores by meiotic (asexual) division. The gametophyte is a multicellular haploid plant structure that develops from the spore and gives rise to the haploid gametes, which are the reproductive organs of the plant.
How can you differentiate a sporophyte from a gametophyte in bryophytes?
During the asexual phase, the gametophyte generation is represented, and during the sexual phase, the sporophyte generation is represented by the sexual phase. Sporophytes are also diploid, which means that they have two sets of chromosomes, as opposed to monozygotic. Gametophytes, on the other hand, are haploid, meaning that they only have one set of chromosomes in their genome.
