Reproduction
Reproduction the ability of an organism to produce new individuals is one of the characteristics that distinguish living things from non-living things.
Two types of Reproduction:
Asexual Reproduction It is the creation of a new organism from a single or one parent and does not involve the combination of gametes or sex cells.
Asexual Reproduction are not for human being and animals.
Types of Asexual Reproduction:
Spore formation is a type of asexual reproduction where organism reproduce by forming spores.
Spores are the single-called reproductive unit of flowering.
Ex: Mushroom
Budding a new organism is formed from an outgrowth from the parent.
Ex: Hydra, Yeast
Fission an organism grows and duplicates its genetic material the divides into two.
“Split or divide”
Ex: SEA ANEMONES, BACTERIA, STARFISH
Fragmentation It happens when new organisms grows from a fragment of the parent.
Ex: Starfish
Regenation It occurs when a body part is detached from the parent. This part grows and develop into a completely new individual.
Ex: Starfish
Lizard born through egg.
Vegetative Propagation It is a method wherein new plants are obtained from the parts of old plants like stems, roots and leaves without the use of any reproductive parts.
Ex: strawberry, squash, Onion
Sexual Reproduction It is the type of reproduction that involves two parents and combination of gametes (sex cells) to produce a new organism.
Sexual Reproduction:
FERTILIZATION > ZYGOTE > EMBRYO
Sexual Reproduction:
Sperm cell is for mens
Egg cell is for women
