30 Questions
Mitosis is the process of producing gametes.
False
Meiosis is the process of reducing chromosome number from 2n to 1n.
True
Interphase occurs before both mitosis and meiosis.
True
During prophase I of meiosis, homologous chromosomes form tetrads.
True
Metaphase I of meiosis is when the tetrads line up at the cell equator.
True
Anaphase II of meiosis is when the centromeres split and sister chromatids are pulled towards opposite poles of the cell.
True
Interkinesis is a phase that occurs between meiosis I and meiosis II and involves DNA replication.
False
Meiosis II is the separation of sister chromatids and is similar to the events of mitosis.
True
During meiosis, four genetically distinct haploid cells are produced.
True
Fertilization triggers the completion of meiosis II in the ovum.
True
The cytoplasm is the cellular material between the cell membrane and the nucleus.
True
The cytosol is a gel-like intracellular fluid mainly composed of water.
True
The cytosol is a suspension of carbohydrates, proteins, lipids, and dissolved ions.
True
The cytosol has a higher concentration of potassium (K+) compared to extracellular fluid (ECF).
True
The cytosol has a lower concentration of sodium (Na+) compared to extracellular fluid (ECF).
True
Ribosomes are non-membranous organelles and are in direct contact with the cytosol.
True
Ribosomes are the sites of protein synthesis.
True
The centrosome is the microtubule organizing center of the cell.
True
The centrosome contains a pair of microtubules called centrioles.
True
The cytoskeleton is composed of protein filaments and is important for cell shape and movement.
True
True or false: The nucleus is the largest membranous organelle in the cell?
True
True or false: The nucleolus is a membranous organelle within the nucleus?
False
True or false: Chromosomes are composed of DNA coiled around histone proteins?
True
True or false: Chromatin is the most common state of DNA in cells that are not dividing?
True
True or false: Each somatic cell contains 46 chromosomes?
True
True or false: Homologous chromosomes are identical pairs of chromosomes from each parent?
False
True or false: Interphase is the period of normal cell activities and growth?
True
True or false: DNA replicates during the G2 phase of interphase?
False
True or false: Mitosis is the division of the nuclear material?
True
True or false: Cytokinesis is the division of the cytoplasm?
True
