Prokaryotes
a. display a greater diversity of metabolism, compared to eukaryotes.
b. have larger cells, on average, than most eukaryotes.
c. lack a self-generated plasma membrane.
d. use sexual reproduction to generate offspring.

Key Concepts

Reproductive Methods

Prokaryotes primarily reproduce asexually through processes such as binary fission, where a single cell divides into two identical daughter cells. They do not typically engage in sexual reproduction, although they may exchange genetic material through mechanisms like conjugation, transformation, or transduction.

Plasma Membrane

Both prokaryotes and eukaryotes have a plasma membrane, which is a lipid bilayer that encloses the cell, controlling the movement of substances in and out of the cell. Despite their simplicity, prokaryotes rely on their plasma membranes for essential functions such as energy generation and environmental interaction.

Prokaryotes

Prokaryotes are unicellular organisms that lack a membrane-bound nucleus and other organelles. They include two domains of life, Bacteria and Archaea, and are generally characterized by their simpler cell structure compared to eukaryotes.

Metabolic Diversity

Prokaryotes exhibit a remarkable diversity in metabolic processes. They can utilize a wide range of energy sources, including photosynthesis, respiration, and various forms of anaerobic metabolism, enabling them to inhabit diverse and often extreme environments.

Cell Size Comparison

Prokaryotic cells are typically much smaller than eukaryotic cells. This size difference is due to the simpler internal structure of prokaryotes, which lack the compartmentalization seen in eukaryotic cells.
