Basic Biology Quiz & Flashcards for Beginners

Study Notes

Characteristics of Living Things

Living things acquire materials and energy for growth, development, and maintenance.
Living things grow and develop, which involves an increase in size, mass, and complexity.
Living things respond to external stimuli, such as light, temperature, touch, and sound.

Biology and Life

Biology is the study of living things and their interactions.
The fundamental characteristic of life is the ability to respond to external stimuli.

Diffusion and Osmosis

Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration.
The role of diffusion in living things is to facilitate the exchange of materials and energy.
Osmosis is a type of diffusion that involves the movement of water molecules through a selectively permeable membrane.
Endosmosis is the movement of water into a cell, causing it to swell.
Exosmosis is the movement of water out of a cell, causing it to shrink.

Not Characteristics of Living Things

Not all characteristics of living things include the ability to produce non-living things.

Other Key Points

Growth and development in humans involve physical changes, such as increase in height and weight, and developmental changes, such as changes in mental abilities.
When living things respond to external stimulation, they exhibit a reaction or change in behavior.
