Eukaryotic Cellular Reproduction: Mitosis & Meiosis - Study Guide

Sep 28, 2026

Uploaded by Jacob

Eukaryotic cellular reproduction focuses on mitosis and meiosis, explaining how cells duplicate genetic material and organize chromosomes. The material introduces the big idea that mitosis produces an identical copy while meiosis generates unique gametes with half the chromosome number. It also breaks down the eukaryotic cell cycle into interphase (G1, S phase, G2) and the mitotic phase, detailing DNA replication, sister chromatids, and the transitions leading to nuclear division and cytokinesis. Includes vocabulary terms and practice questions with answer slides.

Mitosis is a type of cellular reproduction where a cell will produce an identical copy of itself with the same number and patterns of genes and chromosomes.
Meiosis, on the other hand, is a special process used to make gametes (sex cells like sperm and eggs) . These cells have half the number of chromosomes of the original cell, and each is unique. | Why Undergo Mitosis?
Cells undergo mitosis for a number of reasons.
Organisms use mitosis to:
· repair damage (as in scars)
· regenerate lost parts (as in the lizard who loses its tail)
· grow in size
· reproduce asexually | | --- | --- | Slide 9 / 103 Slide 10 / 103 | Eukaryotic Cell Cycle | | 1Which one of the following is NOT a function of mitosis?
A growth
B generation of lost parts
C asexual reproduction
D tissue repair
E all are correct | | --- | --- | --- | | The eukaryotic cell cycle has two major divisions: Interphase and the Mitotic phase.
During interphase the cell metabolic activity is very high. It is busy growing and copying it DNA and organelles so it can divide.
The mitotic phase is the actual dividing of the cell. It involves a series of steps (or subphases) . | | | Slide 10 (Answer) / 103 Slide 11 / 103 |

A division of the cell

Most cells spend more than 90% of the total time of the cycle is spent in interphase.
There are 3 distinct sub-phases to interphase:

Answer
| | Slide 13 / 103 Slide 14 / 103 | Gap 1 (G1 phase) | | Synthesis (S-phase) | | | --- | --- | --- | --- | | The cell increases in size.
The cell increases its supply of proteins, particularly those used in the duplication process.
Duplication of organelles occurs | | DNA replication occurs.
At the end of this sub-phase, each chromosome in the cell has doubled. The two copies of a chromosome remain attached at a central point called a centromere. Each copy is then know as a sister chromatid. | | | | | | | Slide 15 / 103 Slide 16 / 103 | Gap 2 (G2 phase)

FAQs

What is the main difference between mitosis and meiosis?

Mitosis produces an identical copy of a cell with the same chromosome and gene patterns. Meiosis produces gametes with half the number of chromosomes, and each gamete is unique.

What happens during interphase?

Most cells spend over 90% of their time in interphase. It includes Gap 1 (G1), Synthesis (S phase), and Gap 2 (G2), during which the cell grows and copies its DNA and organelles.

What are the two sub-phases of the mitotic phase?

The mitotic phase includes mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm).

Why is mitosis important for organisms?

Mitosis helps repair damage, regenerate lost parts, grow in size, and can reproduce asexually.
