Match the following terms with their correct definitions:

Diploid = Cells that contain two sets of chromosomes, one from the ‘mother’ and one from the ‘father’ Haploid = Cells that have only one set of chromosomes Interphase = The non-dividing state where the cell grows to its normal size, makes proteins, and carries out its other everyday functions Mitosis = The division of a nucleus into two genetically identical copies of itself

Match the following stages of the cell cycle with their correct descriptions:

Prophase = The first stage of mitosis, where the genetic material inside the nucleus condenses and the chromosomes become visible Metaphase = The second stage of mitosis, where the chromosomes line up in the middle of the cell Anaphase = The third stage of mitosis, where the chromosomes separate and move to opposite ends of the cell Telophase = The fourth and final stage of mitosis, where the chromosomes begin to uncoil and two new nuclear membranes start to form

Match the following terms with their correct chromosome counts:

Diploid = Human cells have 46 chromosomes Haploid = Gametes (Sperm and Egg Cells) have only one set of chromosomes Interphase = No change in chromosome count Mitosis = No change in chromosome count

Match the following stages of cell division with their correct descriptions:

Interphase = Cell organelles are replicated and energy is built up Prophase = Chromatin shortens and nucleolus and nuclear membrane disappear Anaphase = Spindle fibres contract and sister chromatids separate Telophase = Chromosomes elongate and two nuclear membranes form Signup and view all the answers

Match the following functions with the correct type of cell division:

Growth = Mitosis Asexual reproduction = Meiosis Gamete formation = Meiosis Cell replacement = Mitosis Signup and view all the answers

Match the following terms with their correct definitions:

Carcinogen = Any chemical, biological or physical agent that could possibly be a cause of cancer Benign tumour = A mass of excess tissue that does not invade nearby organs Malignant tumour = A mass of excess tissue that invades nearby organs or travels to new body sites Metastasis = The spread of cancer Signup and view all the answers

Match the following statements about cell division with their correct truth value:

Telophase of mitosis forms a cleavage furrow in plant cells = False The nuclear membrane disappears in the early part of mitosis = True Centromeres give rise to the nuclear spindle = False In multicellular organisms mitosis is primarily used for growth = True Signup and view all the answers

Match the following terms with their correct descriptions:

Mitosis = Cellular process that occurs during interphase Spindle Fibres = Structure that pulls the chromosomes to the poles of the cell during anaphase Cancer = Group of disorders in which control has been lost over the rate of mitosis Metaphase = Stage of mitosis in which the chromosomes are located at the equator of the cell and before they begin to separate Signup and view all the answers

Match the following stages of mitosis with their correct descriptions:

Interphase = Period in which the nucleus is not dividing Metaphase = Chromosomes are located at the equator of the cell and before they begin to separate Anaphase = Chromosomes are pulled to the poles of the cell Telophase = Nuclear envelope reforms and the cell undergoes cytokinesis Signup and view all the answers

Match the following parts of a cell with their functions:

Spindle Fibres = Pull the chromosomes to the poles of the cell during anaphase Nucleus = Cellular structure that is not dividing during interphase Chromosomes = Located at the equator of the cell and before they begin to separate in metaphase Cell Plate = Forms towards the end of mitosis in a plant cell Signup and view all the answers
