Flashcardizz - Mitosis & Meiosis

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes (sperm or eggs).

Front

What is the main purpose of Mitosis?

Back

The main purpose of Mitosis is for growth, repair, and asexual reproduction in organisms.

Front

What is the main purpose of Meiosis?

Back

The main purpose of Meiosis is to produce gametes for sexual reproduction, ensuring genetic diversity.

Front

Define Chromosome.

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What is a Gamete?

Back

A gamete is a reproductive cell (sperm or egg) that carries half the genetic information of an organism.

Front

What is the difference between Diploid and Haploid cells?

Back

Diploid cells contain two complete sets of chromosomes (2n), while Haploid cells contain only one set of chromosomes (n).

Front

What occurs during Prophase in Mitosis?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during Metaphase in Mitosis?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is Crossing Over?

Back

Crossing Over is the exchange of genetic material between homologous chromosomes during Prophase I of Meiosis, leading to genetic variation.
