Which structure pull the chromosomes to opposite sides of the cell in anaphase?
During cell division, the centrioles on either side of the cell produce a fiber-like spindle that attaches to the chromosomes and pulls them apart.
How many daughter cells are produced by a single mitotic cell cycle?
Cytokinesis is the splitting of thecytoplasm and this process starts in late Anaphase and completes in Telophase ( last stage) to produce two separate daughter cells.
What single-celled structure does the sporangium produce?
Spores
What kind of structure do vertical hyphae produce?
mushrooms
What does produce mitosis in plant?
One of the most dramatic activities that eukaryotic cells accomplish is division, in which a cell must copy and sort out evenly all of its genetic material (chromosomes), then pinch itself in two. This process, which produces two genetically identical daughter cells from a single parent cell, is called mitosis. No change in chromosome number occurs during mitosis, because one sister chromatid from each chromosome in the parent cell passes into each of the two daughter cells (the sister chromatids separate during anaphase). Mitosis is the method by which the somatic cells of all multicellular organisms multiply (it is the process by which growth occurs). In addition, plants producegametes by mitosis (they make spores by meiosis). Animals produce gametes viameiosis. The stages of mitosis are detailed on the following pages.
What are the major events that take place during Meiosis you and Meiosis II?
After the 1st meiotic division there are 2 diploid cells. During Meiosis II, these cells are divided (the same steps as the first Division) - and produce 4 daughter cells. These cells (gametes) have half the number of chromosomes of the original cell and so are called hapliod. Phases: 1) Prophase II - cells contain one of each homologous chromosome - but each are in their replicated form (i.e. 2 chromatids attached together) 2) Metaphase II - Chromosomes align in the middle of the cell 3) Anaphase II - Chromatids separate 4) Telophase II - 4 haploid cells formed
If an organism has 16 chromosomes in each of its egg cells what is the diploid number?
EACH CHROMOSOME WILL PRODUCE ONE DUPLICATE CROMATID FOR ITSELF AND THE TWO CHROMATIDS WILL GET ATTACHED TO EACH OTHER THROUGH THE CENTROMERE.SO AFTER DUPLICATOIN 16 SISTER CHROMATIDS WILL BE PRESENT BUT TOTALLY(16 ORIGINAL CHROMATIDS + 16 DUPLICATED CHROMATIDS) 32 CHROMATIDS WILL BE PRESENT

How are mitosis and meiosis similar?
They both have a prophase and an anaphase is for Apex

46
