Types of Reproduction Asexual Sexual
Purpose of Reproduction To make sure a species can continue. –Definition: Reproduction is the process by which an organism produces others of its same kind.
Asexual Reproduction A new organism (sometimes more than one) is produced from one organism. The offspring will have hereditary material uniform with the hereditary material of the parent organism. This means they will be genetically alike.
Types of Asexual Reproduction In Animals Budding Regeneration Fragmentation Fission (Binary fission) In Plants Plantlets (budding) Tubers Runners Bulbs
Budding Process by which a new, duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created. Very common in plants; plantlets
Regeneration The ability to restore lost or damaged tissues, organs or limbs. It is a common feature in invertebrates, like worms and starfish.
Fragmentation In this type of reproduction, the body of the parent breaks into distinct pieces, each of which can produce an offspring.
Fission Also called binary fission. Becoming two by division of the complete organism. A type of cell division.
Tubers The easiest thing to think of when you're trying to understand a tuber is the potato. A tuber has leathery skin and lots of eyes - no basal plate. All of those eyes are the growing points where the plants will emerge. Examples of tubers: Potatoes, sweet potatoes, dahlias
Runners A runner is a stem which grows along the ground rather than upwards.Roots grow down from the runners and these help the plant spread over a large area. Example of plants that make runners are strawberries and bamboo
Bulbs Bulbs (which are referred to as "true bulbs") grow in layers, much like an onion. At the very center of the bulb is a miniature version of the flower itself. Helping the bulb to stay together is something called a basil plate, which is that round and flat hairy thing (those are the beginnings of roots) on the bottom of the bulb. Bulbs reproduce by creating offsets. These little bulbs are attached to the larger bulb.
Sexual Reproduction Requires two sex cells – egg and sperm The egg and sperm join to form an entirely new organism –Different from the parent organism
IMPORTANT! Asexual reproduction results in offspring that are genetically identical to the parent organism Sexual reproduction results in offspring that are genetically different from the parent organisms
