Cell reproduction and the Continuity of Life: Asexual reproduction methods

-One parent -No eggs/sperm -Offspring is identical to parents -Produces many offspring in little time -Simple organisms -Less parental care -No energy spent finding mate

Single parent replicates genetic material than divides into two equal parts.

-Two parents -Eggs and sperm form a zygote -Similar to parent, increases variety -Fewer offspring in less time -Complex organisms -More parental care -Energy spent finding mates

-Single celled amoeba -Bacteria

Part of the cell pushes out forming a growth or bud. The bud eventually pinches off the parent and forms a new organism. Sometimes may remain attached to the parent, but grow independently.

-Yeasts -Hydra -Sponges -Spider Plants

Broken off part of an organism grows into an identical clone of the parent.

-Starfish -Japanese Knotweed

Special cells divide repeatedly, forming a structure that eventually develops into a plant identical to the parent. (Occurs usually in plant stems/roots)

-Strawberries (runners) -Tulips (Bulbs) -Potatoes (eyes) -Grapes (cuttings)

Mitosis produces reproductive cells (spores). Each spore may possibly grow into a new organism identical to the parent. Many have tough outer coatings to resist tough conditions.

-Bacteria -Fungi -Moss -Ferns

Egg develops into an adult without fertilization.

-Balsam wooly aphid -Honey Bees -Whiptail Lizard
