• Reproduction?is the process that leads to the?production of more of the same kind of organism
• Reproduction is fundamental to the?survival?of a population and ultimately, the species
• There are different types of reproduction: sexual and asexual

Sexual Reproduction

• In this type of reproduction, the male and female?gametes?fuse together
  • In humans, the male gamete is the?sperm?and the female gamete is the?egg
  • In plants, the male gamete is in the?pollen?grains and the female gamete is the?ovule

   

• The DNA of the offspring is composed of both?maternal?and?paternal?DNA

Sexual reproduction involves the fusing of two gametes to form a zygote that contains DNA from both parents

Asexual reproduction

• Cells or whole organisms can also reproduce using?asexual reproduction
• Mitosis?is an example of asexual reproduction
• There is only?one parent?involved so an exact?clone?is produced
• The DNA of offspring is?identical?to parental DNA
  • Plants can reproduce asexually through?tubers,?budding?or?runners
  • Single-celled organisms such as?bacteria?or?amoeba?reproduce asexually

   

Asexual reproduction in bacteria involves creating exact copies of the parent cell

• Growth?is defined as a?permanent increase in size
• In?animals, an individual grows larger between the zygote and?adult?stage with?changes in proportion or shape
• In?plants, an individual grows?larger throughout their whole life?with?new?shoots, leaves, branches etc forming year after year
