Continuum of Activities

Continuum of Activities

The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.

This continuum of activities offers:

  • Instructional activities designed to be integrated into planned lessons
  • Questions/activities that grow in complexity
  • Opportunities for differentiation for each student’s level of performance

Activities

  1. Define sexual reproduction.  List two organisms that reproduce sexually.

  2. Define asexual reproduction.  List two organisms that reproduce asexually.

  3. List and describe 3 methods of sexual reproduction.
  1. How are sexual and asexual reproduction similar?  How are they different?
  1. Do you think it is more beneficial to a species to reproduce sexually or asexually?  Use facts to explain your reasoning.

Answer Key/Rubric

  1. Acceptable responses may include, but are not limited to:

    Definition:
  • Sexual reproduction requires two parents.
  • The offspring of sexual reproduction has genetic characteristics from both parents.

List may include:

  • Humans
  • Dogs
  • Cats
  • Horses
  • Orchids
  • sunflowers
  1. Acceptable responses may include, but are not limited to:

    Definition:
  •  Asexual reproduction requires one parent.
  • The offspring of asexual reproductions has genes identical to the parent.
  • Offspring are produced from mitosis.

List may include:

  • Sea stars
  • Sea anemones
  • Bacteria
  • Spider plant (chlorophytum)
  1. Acceptable responses may include, but are not limited to:
  • Fission – parent cells divides into two or more offspring
  • Budding – a new organism develops from a growth due to cell division at a specific spot on the parent organism
  • Vegetative reproduction – plants reproduce by forming plantlets, bulbs, or tubers
  • Spores – plant uses spores to reproduce
  • Fragmentation – new organism grows from a fragment of a parent
  1.  Acceptable responses may include, but are not limited to:
  • Both produce offspring.
  • Both occur in plants and animals.
  • Asexual reproduction requires one parent.
  • Sexual reproduction requires two parents.
  • The offspring of asexual reproductions has genes identical to the parent.
  • The offspring of sexual reproduction has genetic characteristics from both parents.
  1. Acceptable responses may include, but are not limited to:
  • Asexual reproduction requires only one parent.
  • Asexual reproduction can produce multiple offspring at one time.
  • A species can reproduce more rapidly with asexual reproduction.
  • Sexual reproduction requires two parents.
  • Offspring receives genetic material from both parents.
  • DNA from both parents may beneficial for natural selection and/or evolution.
  • Some species that reproduce sexually take a long time period to produce offspring (i.e. gestation periods)
