Grade 7 Cells and Organization Practice Test

Build Grade 7 Science skills with five 10-question practice tests on cell theory, organelles, cell types, transport, microscopy, specialization, and biological organization.

Cells and Organization Practice Tests

These Grade 7 Science practice tests use original questions to build cell biology and organization skills. Students practice cell theory, organelle functions, plant and animal cells, prokaryotic and eukaryotic cells, diffusion, osmosis, active transport, microscopy, specialized cells, and levels of biological organization.

Skills covered

  • Explaining cell theory and identifying the functions of major organelles
  • Comparing plant, animal, prokaryotic, and eukaryotic cells
  • Explaining diffusion, osmosis, active transport, endocytosis, and exocytosis
  • Using magnification, resolution, stains, scale bars, and observations in microscopy
  • Connecting cell specialization to structure and function
  • Ordering cells, tissues, organs, organ systems, and organisms

How to use these practice tests

First identify the structure or process described in the question. Then connect its structure to its function and use the evidence in the observation or comparison. For transport questions, check the concentration gradient and whether the cell must use energy.
