Reproduction in Animals Class 8 Extra Questions Short Answer Questions. Question 1. Explain two modes of reproduction with examples. Answer: There are two modes of reproduction: Sexual reproduction: This type of reproduction takes place by fusion of male and female gametes; e.g., Human beings, mammals like cow, buffalo, etc. 8_ Daughter cells are different from the mother cell in their chromosomal makeup 325 9. Chromosomes are replicated before the division process begins 10. provides cells for the reproduction Of offspring Il. Consists Of two consecutive divisions of the nucleus; chromo- some-s are not replicated before the second division 9.

WC-1 Answers to All Questions and Problems Chapter 1 1.1 In a few sentences, what were Mendel's key ideas about inheritance? ANS: Mendel postulated transmissible factors—genes—to explain the inheritance of traits. He discovered that genes exist in different forms, which we now call alleles.

Match the terms to the cells depicted on the diagram portraying human sexual reproduction.

Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus. Mitosis is essential for the growth of the cells and the replacement of worn ... Sexual reproduction requires fertilization, the union of two cells from two individual organisms. If those two cells each contain one set of chromosomes, then the resulting cell contains two sets of chromosomes. Haploid cells contain one set of chromosomes. Cells containing two sets of chromosomes are called diploid. The female reproductive system provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the ...

Match the terms to the cells depicted on the diagram portraying human sexual reproduction.. The diagram represents reproduction and cell division in a sea urchin (animal) in stages labeled A through F. When a sea urchin reproduces, the female sex cell and the male sex cell unite to form a cell called a zygote. The zygote divides several times in a matter of hours. How many cells will the developing sea urchin have at stage F? Asexual reproduction. Match each Term on the left with the best Descriptor on the right. Each Descriptor may be used only once.

Heather Scoville is a former medical researcher and current high school science teacher who writes science curriculum for online science courses. One of the properties of life is the ability to reproduce to create offspring that can carry on the genetics of the parent or parents to ... Cells produced by meiosis in a diploid-dominant organism such as an animal will only participate in sexual reproduction. Figure 7.6 Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct.

sexual (For a population, the ability to mix and match genes through sexual reproduction gives the population a chance of producing offspring with better combinations of genes to survive the new environment) p259: The root word "homo-" means ___. like (homologous: like chromosomes that form a pair) Answer to Lab 9: Sets in the Java Collection Framework For this week's lab, you will use two of the classes in the Java Collection Framework: HashSet and In this diagram the cell contains 3 pairs of homologous single chromosomes, a total of 6 chromosomes. Since the cell contains a total of 6 chromosomes, it has a chromosome number of 6. Chromosomes A & a represent one pair, B & b represent a second pair, and C & c represent a third pair. Asexual reproduction spans a variety of methods. The simplest single-celled organisms such as archaea, and bacteria, reproduce by binary fission.In this process, the cells simply divide in half, creating a clone of the parent. This method also holds the benefit of being very quick and energy-efficient. For example, bacteria that reproduce by binary fission can give rise to progeny every few hours. Multiple fission also exists, in which an organism splits into more than one offsprings. Certain species of algae and protozoans exhibit multiple fission. Refer more: Asexual reproduction While in multicellular organisms, a similar method called fragmentation is observed. In this process, small pieces break off and grow into new organisms. Another method involves budding, which produces a completely new organism and remains attached to the original body or develops from the original body. A common thread in all this is that the offspring is a direct clone of the parent. The purpose of repr...

If a normal diploid cell has 8 chromosomes, then a. there are 8 homologous pairs of chromosomes per diploid cell b. there are 8 chromatids per diploid cell between S phase and the first division of meiosis c. there are 4 chromosomes per cell after meiosis I d. Sexual Reproduction. During sexual reproduction, two parents are involved. Most animals are dioecious, meaning there is a separate male and female sex, with the male producing sperm and the female producing eggs. When a sperm and egg meet, a zygote, the first cell of a new organism, is formed (Figure below). The zygote will divide and grow into ...

In sexual reproduction, 2 parents each from haploid cells, which join to form offspring True The 2 cells produced during the first cytokinesis in female animals are approximately equal in size and contain the same amount of cytoplasm

You need to know the relationship between mutation, cell cycle, and uncontrolled cell growth potentially resulting in cancer. You need to know the cell cycle, including the process of mitosis and be able to explain the role of mitosis in the formation of new cells and its importance in maintaining chromosome number during sexual reproduction.

used in sexual reproduction. D. Correct - Cells produced through mitosis contain DNA identical to the parent cells, whereas meiosis produces cells that are haploid and often genetically different. Bio.B.1.2 - Explain how genetic information is inherited.

Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells. The cell cycle has two major phases: interphase and the mitotic phase ( Figure 6.3 ). During interphase, the cell grows and DNA is replicated.

Asexual reproduction is a mode of reproduction in which the new offspring arise from a single parent. The offsprings are identical to each other, both physically as well as genetically. They are the exact copies of their parent cell. Hence, they are 'clones'. We observe asexual reproduction in both unicellular and multicellular organisms.

Phases of mitosis. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two ...

Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly-scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs.

Let's try to tie all of this information together and see how it applies to chromosome and chromatid count during the various stages of cell replication. First, during the S phase of interphase, the genetic material of a cell is duplicated. A human has 46 chromosomes (a set of 23 you inherit from your mother, and a set of 23 from your father).

Sexual Reproduction. We coded whether the diagram explicitly depicted sexual reproduction. Diagrams had to show (with either words or images) mating or fertilization to receive a score of 1. Otherwise, they received a score of 0. Simply connecting an adult organism to a zygote with a line was not judged as sufficient to receive a 1.

How is sexual reproduction different from asexual reproduction? Sexual reproduction occurs with only a single parent. Asexual reproduction requires testes and ovaries. Asexual reproduction requires two kinds of cell division. Sexual reproduction requires fertilization of an egg by a sperm.

The female reproductive system provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the ...
