Fundamentals of Cell Structure and Function

From the study guide

Cell Biology Revision Sheet

1. 📌 Essentials

  • All living organisms are composed of cells, the fundamental units of life.
  • Cells are classified into prokaryotic (no nucleus) and eukaryotic (nucleus present).
  • The nucleus contains genetic material and controls cellular activities.
  • Organelles like mitochondria produce energy;osomes synthesize proteins.
  • The cell membrane is a phospholipid bilayer regulating substance exchange- Cell walls provide structural support; composition varies (cellulose, chitin, peptidoglycan).
  • Cytoskeleton maintains cell shape and facilitates intracellular transport.
  • Prokaryotic DNA is in the cytoplasm; eukaryotic DNA is in the nucleus.
  • Lysosomes degrade waste; vacuoles store nutrients and maintain turgor in plants.
  • Chloroplasts perform photosynthesis in plant cells.
