What is the primary method of asexual reproduction?
Mitosis
What type of reproduction involves the fusion of gametes?
Sexual reproduction
True or False: Meiosis results in the production of diploid cells.
False
How many daughter cells are produced at the end of mitosis?
Two
What is the end result of meiosis?
Four haploid gametes
Fill in the blank: In asexual reproduction, the offspring are genetically ______ to the parent.
identical
What is the purpose of meiosis in organisms?
To produce gametes for sexual reproduction
Which process is responsible for genetic variation in offspring?
Meiosis
What is the role of the compound microscope?
To magnify small objects for observation
List the two main types of lenses in a compound microscope.
Objective lens and eyepiece (ocular) lens
True or False: Mitosis is used for growth and repair in multicellular organisms.
True
What phase of meiosis involves the separation of homologous chromosomes?
Meiosis I
What is the magnification formula for a compound microscope?
Total magnification = eyepiece magnification × objective magnification
Which phase of mitosis is characterized by the alignment of chromosomes at the cell’s equator?
Metaphase
Fill in the blank: The two stages of meiosis are ______ I and ______ II.
Meiosis I and Meiosis II
What is the primary difference between mitosis and meiosis?
Mitosis results in identical cells, while meiosis results in genetically varied cells.
True or False: A compound microscope can only be used to view living cells.
False
What is cytokinesis?
The division of the cytoplasm during cell division.
Name one advantage of asexual reproduction.
Rapid population increase
What is the term for the exchange of genetic material between homologous chromosomes during meiosis?
Crossing over
Mitosis
Mitosis is the process of cell division in which a single cell divides to produce two genetically identical daughter cells, each with the same number of chromosomes as the original cell.
Meiosis
Meiosis is the process of cell division that produces four genetically unique daughter cells, each with half the number of chromosomes as the original cell. It occurs in two stages: meiosis I and meiosis II, and is essential for sexual reproduction.
