Biological Concepts and Levels of Organization Quiz

Levels of biological organization exclude the chemical level, which focuses on molecules and atoms.

Living organisms possess all the listed characteristics, including organization, metabolism, growth, and reproduction.

Prokaryotic cells are typically unicellular and lack a nucleus or membrane-bound organelles.

ATP (adenosine triphosphate) serves as the primary energy carrier in cells.

The endoplasmic reticulum, particularly the smooth ER, is involved in drug metabolism and detoxification in liver cells.

Organs are composed of tissues and work together to carry out specific functions within an organism.

Mitochondria generate energy in the form of ATP through cellular respiration.

Humans are multicellular organisms composed of many specialized cells organized into tissues and organs.

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plants.

Ecosystems encompass all the living organisms in a particular area interacting with each other and their nonliving environment.

Fungi are eukaryotic organisms, characterized by cells with membrane-bound organelles and a nucleus.

Eukaryotic cells have a true nucleus enclosed within a membrane, distinguishing them from prokaryotic cells.

Bacteria are unicellular organisms lacking a nucleus and other membrane-bound organelles, characteristic of prokaryotic cells.

Prokaryotic cells lack a true nucleus and membrane-bound organelles, with genetic material freely floating in the cytoplasm.

Fungi, such as yeasts and molds, are eukaryotic organisms with membrane-bound organelles and a true nucleus.
