10 Questions
Explain the function of platelets in the blood.
Platelets are tiny fragments of cells that help the blood to clot when an individual gets cut.
What are blast cells and where are they usually found?
Blast cells are immature blood cells usually found in the bone marrow, where blood cells originate before circulation.
Define the innate classification of white blood cells (WBC).
The innate classification of WBC refers to the cells that are present from birth and are generalists, meaning they do not defend against a specific enemy.
Explain the process of cell differentiation.
Cell differentiation refers to the process where cells commit to perform specific jobs, allowing cells to specialize and perform specific functions in the body.
What is the function of stem cells in the body?
Stem cells serve as a reservoir for other cells and remain undifferentiated, allowing them to develop into various specialized cell types as needed.
What are the three main stages of the cell cycle and what occurs in each stage?
G1: the cell grows and makes copies of organelles. S: DNA is duplicated. G2: the cell continues to grow and check integrity.
What happens during interphase, the longest stage of the cell cycle?
During this stage, the cell performs its normal function while preparing to divide. It goes through various checks, including checking if it is old enough to divide, if the DNA has any mutations, if the signals to divide are present, and if the right number of similar cells are present.
What is the significance of homologous chromosomes in sexually reproducing organisms?
Sexually reproducing organisms have 2 copies of similar DNA, known as homologous chromosomes, which carry very similar genes. Different versions are known as alleles.
What are the 5 stages of mitosis and what occurs in each stage?
Early prophase: Sister chromatids are visible and attached to the centromere, spindle fibers start forming the centriole, and chromatin becomes chromosomes. Late prophase: Sister chromatids are held by spindle fibers at the centromere and are randomly spread out. Metaphase: Sister chromatids meet at the equator of the cell. Anaphase: Sister chromatids are separated to opposite poles of the cell.
What are organelles and what role do they play in the cell cycle?
Organelles are cellular structures that perform specific functions. During the S phase, DNA makes copies of itself.
