Reproduction Flashcards
reproduction
involves life process
life process
produces new cells/organism
repair tissues
growth
Two types of reproduction
asexual and sexual
asexual reproduction
only 1 parent is involved
cell division occurs through mitosis
DNA of offspring is a exact copy (clone) of the parent
no genetic variation between the parent and offspring
Sexual reproduction
cell division occurs through meiosis (gives variation)
DNA of the offspring is 1/2 from each parent and Ida’s genetically different
Types of asexual reproduction
Binary fission, budding, sporulation, regeneration, vegetative propagation
Binary fission
Equal division of nuclear material and cytoplasm
Budding
Equal division of nuclear material and unequal cytoplasm
Sporulation
Release of spores
Regeneration
Producing an organism from each half of parent cell
Vegetative propagation
new plants form from roots, leaf, or stem (grafting)
Differences in mitosis in an animal cell and a plant cell
telophase
Telophase in a plant cell
form cell plate to divide the cell
*no centrioles
telophase in an animal cell
cleavage/pinches membrane in
*has centrioles
cancer
uncontrolled and unregulated cell division
