Introduction to Cell Division quiz Flashcards

Asexual reproduction involves one parent and produces genetically identical offspring, while sexual reproduction involves two parents and produces genetically diverse offspring.

Binary fission is used by single-celled organisms for asexual reproduction.

Meiosis is closely linked to sexual reproduction as it forms the gametes or sex cells.

The two main types of cell division are mitosis and meiosis.

Cell division replaces dead tissue cells, aiding in tissue repair.

A cell must replicate or duplicate its DNA before it can divide.

The genome is the complete set of all of a cell's DNA.

Chromatin is loosely packed DNA found in non-dividing cells, while chromosomes are tightly packed DNA found in dividing cells.

Meiosis forms the sex cells (sperm and egg) that fuse to create genetically diverse offspring.

Genetic diversity in sexual reproduction increases the variability and adaptability of offspring.

The zygote, formed by the fusion of sperm and egg, undergoes cell division to develop into a fetus.

Cell division allows a single-celled zygote to grow into a fully mature adult by continuously producing new cells.

In a non-dividing cell, DNA is organized into loosely packed chromatin.

During cell division, DNA condenses into tightly packed chromosomes to facilitate its movement within the cell.
