Emergent Properties

1 / 15

What is meant by “emergent properties” in biology?

A) Properties that exist only in atoms

B) Properties found only in DNA molecules

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

D) Properties that disappear when cells divide

2 / 15

Why are emergent properties not seen in individual organelles?

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

B) Organelles are non-living

C) Organelles are too large

D) Organelles do not contain water

3 / 15

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

A) Organelles lose their functions

B) DNA disappears

C) Cells break into molecules

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

4 / 15

What is the emergent property at the cellular level?

A) Ability of atoms to bond

B) Ability of the cell to carry out life processes

C) Ability of organelles to float

D) Ability of molecules to dissolve

5 / 15

Which statement best describes the relationship between cells and tissues?

A) Tissues are independent of cells

B) Tissues form cells

C) Cells lose their structure in tissues

D) Cells combine to form tissues with specialized functions

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 lose DNA

B) They stop metabolism

C) They contain fewer organelles

D) They perform specialized coordinated functions

8 / 15

What happens when tissues form an organ?

A) They stop communicating

B) They lose specialization

C) They perform unrelated functions

D) They combine to perform a specific complex function

9 / 15

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

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

B) Diffusion of oxygen

C) A mitochondrion producing ATP

D) DNA replication in nucleus

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 performs multiple coordinated functions using different tissues

D) It does not use energy

11 / 15

What is the emergent property at the organ system level?

A) DNA mutation

B) Digestive system

C) Mitochondria cluster

D) Neuron network only

13 / 15

Why is a system more efficient than a single organ?

A) It stops metabolism

B) It has fewer cells

C) It has no specialization
