Types of Asexual Reproduction

Question 1

Binary Fision

Answer 1

(Mitosis)

• the splitting of cells
• genetically identical
• very similar to mitosis

Question 2

Budding

Answer 2

• when a new organism develops from a bud of an existing organism.
• until the new organism matures, it remains attached to the parent organism.

ex. hydro and yeast

Question 3

Parthenogensis

Answer 3

• when a female can produce an embryo without fertilizing an egg with sperm.

ex. jawed vertebrates like lizards

Question 4

Spores

Answer 4

• most common mode of asexual reproduction
  -produced by one parent only (through mitosis) and are genetically identical to the parent
  -spores allow fungi to expand their distribution and colonize new environments
  -once spores are developed, the organism is released into the environment to grow and thrive

Question 5

Vegetative Reproduction

Answer 5

• any form of asexual reproduction occurring in plants where a new plant grows from a fragment of the parent cell
• or it grows from a specialized reproductive structure
  
  • ex. stolon, rhizome, tuber, corm, or bulb

Question 6

Fragmentation

Answer 6

• reproduction where a fragment of the parent breaks off and develops into an entirely new but genetically identical individual
• parent will eventually regenerate, or regrow the missing piece, so in the end there are 2 new individuals from one.

ex. sea stars

Question 7

Grafting

Answer 7

• artificial asexual reproduction used to produce plants combining favourable stem characteristics with favourable root characteristics
• stem of the plant to be grafted is a scion, the root is called a stock

Question 8

Plant Tissue Cultures

Answer 8

• plant cloning
• asexual reproduction of plants to produce duplicates from one plant specimen
• good characteristics can then be passed down to further generations
• method involves micropropagation and plant cell structure
