Life functions/Cells Flashcards
1st Unit
What is the science of Biology
Is the “study of life”
Characteristics of Life
Cells, Metabolism, Homeostasis, and Reproduction
Cells
Basic units of structure & function. All living things are made up of 1 or more cells
Metabolism
Chemical reactions in cells
Homeostasis
The ability of the body to maintain a constant internal balance, regardless of the external environment. Internal Balance
Reproduction
Produce offspring
Energy
Required to maintain life and for growth and development
8 functions you must carry out to be considered alive
Nutrition, Transport, Cell Respiration, Excretion, Synthesis Regulation, Growth, and Reproduction
Nutrition
To eat food
Types of Nutrition
Autotrophic and Heterotrophic
Autotrophic
Organisms that make their own food
Heterotrophic
Organisms that get their food from the environment
Transport
Organisms circulate and absorb materials through the cells (food and waste)
Cell Respiration
Releases energy stored in nutrients
Types of Cellular Respiration
Aerobic and Anaerobic
