Cell Reproduction

The document compares and contrasts asexual and sexual reproduction. Sexual reproduction involves two parents, the fertilization of an egg by sperm which contains half of each parent's DNA, resulting in offspring that differ genetically from the parents. Asexual reproduction involves one parent and no fertilization, with identical offspring produced through cell division containing all of the parent's DNA. The document defines key terms and provides examples of different types of asexual reproduction like binary fission, budding, and regeneration.

 Describe the differences between sexual and
asexual reproduction
Sexual Reproduction
 Sexual  1. 2 parents
Reproduction  2. Sex cells: sperm and
egg
 3. Sperm and egg join=
fertilization
 4. Offspring look different
from parent (mixed DNA)

Sexual Reproduction

Fertilization: part of the process of sexual reproduction in which


a male reproductive cell and a female reproductive cell combine
to form a new cell that can develop into a new organism.
Asexual Reproduction
 Asexual  1. One parent
Reproduction  2. No sex cells
 3. Offspring produced by
cell division
 4. Offspring identical to
parent (same DNA)
 5. Several types in plants
and animals
Types of Asexual Reproduction
 Binary  1. Organism divides in half
Fission  2. 2 identical daughter cells
produced
 3. Daughter cells are half
the parent’s size
 4. Daughter cells grow,
then divide too
 5. In bacteria
Types of Asexual Reproduction
 Budding  1. Small bud grows out of
parent cell
 2. Two different sized cells
made (with identical DNA)
 3. Bud breaks off and
grows
 4. In yeast and hydra
Types of Asexual Reproduction
 Regeneration  1. Repair/ grow lost body
parts
 2. Left over cells divide to
make more cells
 3. Lobsters, starfish, lizards
