Cell Reproduction Flashcards
asexual reproduction
reproduction of an offspring with just one parent
base pairs
-two chemical bases that join together to form a gene in DNA
- Adenine joins with Thymine
-Cytosine joins with Guanine
budding
-asexual reproduction where the parent sprouts a “mini me”
double helix
-the shape of a DNA molecule
-a twisted ladder
egg cells
female sex cells
fertilization
when an egg and sperm cell join together
fission
asexual reproduction when an organism splits creating two identical organisms
fragmentation
-asexual reproduction where offspring can grow from a piece of the parent
-example- a starfish loses an arm and the arm regrow but also the lost arm grows a body
gene
chemical part of DNA that determines traits ( how an organism will look- brown eyes)
meiosis
-the division of a sex cell
-it is necessary to grow more organisms
mitosis
-process where cells are copied
-it is necessary to replace damaged cells
sexual reproduction
reproduction of offspring with two parents
sperm cells
male sex cells
zygote
the first cell that is made from fertilization (sperm and egg uniting)
