nuclear envelope

The inner membrane of the mitochondrion when examined with transmission electron microscopy appears ___________.

folded with a large surface area to allow energy production (ATP synthesis) to take place.

Archaea and bacteria are both prokaryotes. They however distinguish themselves by:

the composition of the membrane

share the same basic chemistry.

Study Notes

Cell Characteristics

  • Living cells differ from non-living cells due to distinct characteristics
  • Organelle shown in the figure: Mitochondrion, function: generate energy for the cell

Cell Types

  • Prokaryotic cells distinguished from eukaryotic cells by the absence of a true nucleus
  • Dendritic cells have a long, branched structure, requiring many connections with neighboring cells

Nucleus Function

  • Nucleus: main function is to store genetic information

Cellular Processes

  • Exocytosis: process by which vesicles are secreted from cells

Cell Component Identification

  • Rough Endoplasmic Reticulum (RER): indicated by the line labeled "3" (green)

Mitochondrial Structure

  • Inner mitochondrial membrane: appears folded and cristae-like when examined with transmission electron microscopy


  • Archaea and Bacteria: both prokaryotes, distinguished by different membrane lipids and metabolic processes

Common Traits

  • All living cells: share common characteristics that distinguish them from non-living cells
