Comparing Mitosis and Meiosis Observe: 1. Organisms have a number of chromosomes in each of their body or somatic cells that is unique for that organism. This is called their diploid or 2n number. 2. Cells go through a cell cycle‚ whereby‚ much of the cycle does not include division‚ but at the end of this interphase in their cycle‚ they go through mitosis. 3. Cells replicate their DNA in the S phase of the cell cycle. 4. In the process of mitosis‚ cells replicate their DNA in the nucleus‚ form

Meiosis and mitosis are both types of cell division. Cell division is the reproduction of cells‚ and requires the duplication of chromosomes. Mitosis takes place when the nucleus divides. Meiosis is a type of cell division that produces haploid gametes in diploid organisms. Mitosis and meiosis are two very different processes. While meiosis only requires the cell to divide twice‚ the cell only divides once during mitosis. This causes meiosis to produce four cells and mitosis to produce two cells

Mitosis: (onion roots) Root cells are good for observing mitosis; this is because they’re in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once‚ also allowing us to examine the different stages of mitosis. Stages: 1. Interphase: DNA replicates‚ but has not formed the condensed structure. They remain as loosely coiled chromatin. The nucleus is still intact. 2. Prophase: The DNA molecules progressively shorten

to each other. Important for mitosis and meiosis. The relationship is that each chromosome consists of chromatin. Once replicated‚ a chromosome consists of two identical chromatids‚ which are attached to a section of the DNA called the centromere. 3. List the phases of mitosis and describe what is happening in each phase. Mitosis‚ results in identical cells. 46 chromosomes. It is important for: maintenance‚ repair‚ growth‚ and regeneration. The phases of mitosis are prophase‚ metaphase‚ anaphase

The short story "The Hand" is about the role of the sexes. The author was a significant feminist voice in the twentieth century and in this story she showed that men where said to be dominant over females. She wrote the story close to home for young‚ female brides who have married older‚ more experienced men. The young women were already in a place of submission because they just left their parents. Colette points out an uneven power in marriage and shows how the young wife slowly sees that her

Mitosis is the process in which a cell breaks apart its chromosome to eventually produce two identical daughter cells. The cell spends 10% of its time in mitosis. The cell goes through four stages in order to complete this task. The stages are Prophase‚ Metaphase‚ Anaphase and Telophase. Mitosis only occurs in eukaryotic cells and the process is different for different species. Mitosis is fast and very complex. The first phase is Prophase. In prophase‚ the chromosomes the chromosomes start to

than an hour‚ while the S phase might take 10–12 hours‚ or half the cycle. The rest of the time would be divided between the G1 and G2 phases. The G1 phase varies most in length from cell to cell. The mitotic (M) phase consists of mitosis and cytokinesis. Mitosis is usually broken into five subphases: prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. During prophase‚ the nucleolus fades and chromatin

Abstract: The question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the
