Reproduction and Growth of Organisms

VIDEO: Asexual Reproduction

This is a fun video from Mark Drollinger on Youtube. It explains the difference between sexual and asexual reproduction. Check it out! Works on all devices.

VIDEO: Animal Attraction

In the tropical forests of New Guinea, one male is dedicated to making an unforgettable first impression.Watch this interesting video from BBC to understand mate selection.

Click and Clone

Try cloning a mouse with this fun interactive tool called “Click and Clone”. This is brought to you by Learn Genetics from University of Utah. Follow the steps and see if you can clone the mice! Flash is required.

VIDEO: Where do genes come from?

This video from TedEd and Carl Zimmer shows how mutations in our DNA can occur and the impact that those mutations have on organisms.

KEY CONCEPTS

Growth & Development of Organisms (LS1.B)

  • Organisms reproduce, either asexually or sexually, and transfer their genetic information to their offspring. (MS-LS3-2)
  • Animals engage in characteristic behaviors that increase the odds of reproduction. (MS-LS1-4)
  • Plants reproduce in various ways, sometimes depending on animal behavior and special features for reproduction. (MS-LS1-4)
  • Genetic factors as well as local conditions affect the growth of the adult plant. (MS-LS1-5)

Inheritance of Traits (LS3.A)

  • Genes are located in the chromosomes of cells. Chromosomes are found in pairs. Genes control the production of proteins, which affects the traits of the individual. Mutations, or changes to the gene can result in a change in traits. (MS-LS3-1)

Variation of Traits (LS3.B)

  • In sexually reproducing organisms, each parent contributes half of the genes acquired (randomly) by the offspring. (MS-LS3-2)
  • In addition to variations that arise due to sexual reproduction, genetic information can be altered because of mutations. Some changes are beneficial, some harmful, and some are neutral to the organism. (MS-LS3-1)

Natural Selection (LS4.B)

In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. Humans have done this for thousands of years with our domesticated plants (rice, wheat etc.) and animals (dogs, cats, birds, fish etc.). (MS-LS4-5)

About NGSS

Next Generation Science Standards is a multi-state effort to create new education standards that are “rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education.”
