Science NetLinks
Type: Lesson/Unit Plan

Overview:

This is the first of two lessons about reproduction in plants. This lesson covers how most plants normally reproduce--sexually. Students will learn the parts of the flower and the process of sexual reproduction in plants. The second Science NetLinks lesson in this series, Plants 2: Plant Propagation, teaches how plants can be forced to reproduce asexually.

Content Standard(s):
Science
SC2015 (2015)
Grade: 7
Life Science
2 ) Gather and synthesize information to explain how prokaryotic and eukaryotic cells differ in structure and function, including the methods of asexual and sexual reproduction.


NAEP Framework
NAEP Statement::
L8.1e: All organisms are composed of cells, from one cell only to many cells. About two-thirds of the weight of cells is accounted for by water, which gives cells many of their properties. In multicellular organisms, specialized cells perform specialized functions. Organs and organ systems are composed of cells and function to serve the needs of cells for food, air, and waste removal. The way in which cells function is similar in all living organisms.

NAEP Statement::
L8.2: Following fertilization, cell division produces a small cluster of cells that then differentiate by appearance and function to form the basic tissues of an embryo.

NAEP Statement::
L8.9a: Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species.

NAEP Statement::
L8.9b: Some organisms reproduce asexually.

NAEP Statement::
L8.9c: Other organisms reproduce sexually.

Evidence Of Student Attainment:
Students:
  • Gather and synthesize information with attention given to accuracy, credibility, and bias.
  • Explain, based on gathered information, the differences between prokaryotic and eukaryotic cells as they relate to structure, function, and methods of reproduction.
Teacher Vocabulary:
  • Cell
  • Prokaryotic cells
  • Eukaryotic cells
  • Structure
  • Function
  • Asexual reproduction
  • Sexual reproduction
  • Mitosis
  • Meiosis
  • Chromosome
  • DNA
Knowledge:
Students know:
  • Prokaryotic cells are microscopic, single-celled organisms that have neither a distinct nucleus with a membrane nor other specialized organelles.
  • Prokaryotes include the bacteria and cyanobacteria.
  • The function of prokaryotic cells.
  • The reproductive methods of prokaryotic cells.
  • Eukaryotic cells consist of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus.
  • Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
  • The function of eukaryotic cells.
  • The reproductive methods of eukaryotic cells.
Skills:
Students are able to:
  • Obtain information about cells, including structure, function, and method of reproduction, from published, grade-level appropriate material from multiple sources.
  • Determine and describe whether the gathered information is relevant.
  • Use information to explain how prokaryotic and eukaryotic cells differ.
Understanding:
Students understand that:
  • Prokaryotic and eukaryotic cells differ in structure and function, as well as method of reproduction.
