CURRICULUM TOOL: ASEXUAL AND SEXUAL REPRODUCTION
NYS Living Environment Core Curriculum Standard 4:
Students will understand and apply scientific concepts, principles, and theories pertaining to the
physical setting and living environment and recognize the historical development of ideas in science.
Key Idea 4 The continuity of life is sustained through reproduction and development
 Reproduction and development are necessary for the continuation of any species
 Some organisms reproduce sexually with all the genetic information coming from one
parent. Other organisms reproduce sexually with half the genetic information typically
contributed by each parent. Cloning is the production of identical genetic copies.
 The processes of meiosis and fertilization are key to sexual reproduction in a wide variety
of organisms. The process of meiosis results in the production of eggs and sperm which
each contain half the genetic information. During fertilization, gametes unite to form a
zygote, which contains the complete genetic information for the offspring.
 The zygote may divide by mitosis and differentiate to form specialized cells, tissues, and
organs of multicellular organisms
 Human reproduction and development are influenced by factors such as gene expression,
hormones, and the environment. The reproductive cycle in both males and females is
regulated by hormones such as testosterone, estrogen, and progesterone.
Curriculum-Based Questions
 What is sexual and asexual reproduction?
 What are the advantages and disadvantages
of both asexual and sexual reproduction?

 What are the main events of the cell cycle?
Draw and label diagrams of the cell cycle.
(Mitosis and Meiosis)
 How does the growth of a tumor relate to
normal cell growth and division?
 How do cells become specialized for
different functions?
