reproduction Flashcards
what is budding
cell divisiom that forms a bud and as it grows , forming an identical copy of its parent and then seperating from the parent to become independant
fission
a parent cell splits in half and produces two new cells
regeneration
regeneration allows an organism to grow back parts that may become missing or worn away some organisms can generate a whole new organism from just one part
fragmentation
a small peice or fragment breaks away from the main mass of the organism which then grows into a new fungi
what are advantages of sexual reproduction
- genetic variation / diversity
- adapt for survival
what are advantages to asexual reproduction
no energy required
no parental care required
what are two disadvantages for asexual reproduction ?
no diversity or genetic variation
difficulty adapting for survival .
what are disadvantages for sexual reproduction
Longer reprodcutive process
Needs energy to find a mate
The production of offspring is usually external so the parent can have LOTS of offspring in a very short amount of time.
what does fragmentation happen in
fungi , example : mushrooms
what is vegatative propagation
Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem
what is an example of regeneration
starfish , lizard
asexual reproduction is more common in
invertebrate animals then vertebrate animals
two organisms that reproduce through vegetative propagation
strawberrys and potatos , carotts
what two organisms reproduce through binary fission
paramecium , amoeba
what organisms reproduce through budding
hydra , yeast
whats the difference between animal and plant cells
The most important difference between plant and animal mitosis is the cytokinesis. In plants, a cell plate is formed, whereas in animals a cleavage is formed.
what do spores occur in
mold and ferns
what is cutting
A part of a plant, typically a stem or leaf, is cut off and planted. Adventitious roots develop from the cuttings and a new plant forms
