Emergent Properties

1 / 15

What is meant by “emergent properties” in biology?

A) Properties that exist only in atoms

B) Properties that appear at higher levels of organization due to interaction of simpler components

C) Properties found only in DNA molecules

D) Properties that disappear when cells divide

2 / 15

Why are emergent properties not seen in individual organelles?

A) Organelles do not contain water

B) Organelles are too large

C) Organelles are non-living

D) Organelles alone do not interact to form higher-level functions

3 / 15

Which best explains the transition from subcellular organelles to a cell?

A) Cells break into molecules

B) DNA disappears

C) Organelles combine and interact to form a functional unit (cell)

D) Organelles lose their functions

4 / 15

What is the emergent property at the cellular level?

A) Ability of organelles to float

B) Ability of molecules to dissolve

C) Ability of atoms to bond

D) Ability of the cell to carry out life processes

5 / 15

Which statement best describes the relationship between cells and tissues?

A) Cells combine to form tissues with specialized functions

B) Tissues form cells

C) Cells lose their structure in tissues

D) Tissues are independent of cells

6 / 15

What is an emergent property at the tissue level?

A) DNA replication

B) Ability of cells to photosynthesize individually

C) Coordinated function like contraction in muscle tissue

D) Production of ATP

7 / 15

Why are tissues more functional than individual cells?

A) They perform specialized coordinated functions

B) They contain fewer organelles

C) They lose DNA

D) They stop metabolism

8 / 15

What happens when tissues form an organ?

A) They combine to perform a specific complex function

B) They perform unrelated functions

C) They lose specialization

D) They stop communicating

9 / 15

Which is an example of emergent properties at the organ level?

A) DNA replication in nucleus

B) Diffusion of oxygen

C) A mitochondrion producing ATP

D) Heart pumping blood due to muscle, connective, and nerve tissues working together

10 / 15

Why is an organ more efficient than a single tissue?

A) It works independently of the body

B) It contains fewer cells

C) It does not use energy

D) It performs multiple coordinated functions using different tissues

11 / 15

What is the emergent property at the organ system level?

A) Combined function of organs working together for a major body process

B) Protein folding

C) DNA mutation

D) Single cell respiration

12 / 15

C) Neuron network only

D) Digestive system

13 / 15

Why is a system more efficient than a single organ?

A) It has fewer cells

B) It stops metabolism

C) It performs a complete physiological function through multiple organs
