DESCRIPTION
Study of Biology. What is Biology?. Biology is the study of all living things Living things are called organisms Organisms include bacteria, protists , fungi, plants, & animals. All Living Things Share Common Characteristics. Basic Unit is the Cell (Have order) They Reproduce - PowerPoint PPT PresentationTRANSCRIPT

All Living Things Share Common
Characteristics1. Basic Unit is the Cell
(Have order)2. They Reproduce3. All Based On Universal
Genetic Code (DNA)4. Grow & Develop

Common Characteristics
5. Obtain & Use Materials & Energy (Metabolism)
6. Respond To Their Environment
7. Maintain A Stable Internal Environment
8. AS A GROUP, Living Things Evolve, That Is They Change Over Time

All Organisms are made of Cells

Cell FactsCells are the smallest living unit of an organismCells are complex & highly organized

Organisms are Grouped by their Number of Cells
Unicellular Organisms–Living Organism Made Up Of One Cell
Multicellular Organisms–Living Organism Made Up Of Many, Specialized Cells

Organisms Reproduce to Pass on their Genetic Traits

Two Types of Reproduction
Sexual Asexual Reproduction
Reproduction

Cells Have a Genetic Code
![Page 12: Study of Biology](https://reader031.vdocuments.mx/reader031/viewer/2022012914/56816256550346895dd2a345/html5/thumbnails/12.jpg)
Genetic Code
DNA carries the genetic code for all organismsAll organisms contain DNA

Organisms Grow & Develop

Growth & DevelopmentOrganisms grow by producing MORE CELLS & by cell ENLARGEMENTOrganisms develop as they mature into an adult organism

Cells Require Food & Energy

MetabolismSum of all the chemical reactions in an organismAll require energySunlight is the ultimate energy for life on Earth

MetabolismCellular Respiration –Cells releasing the chemical energy stored in foods
6O2 + C6H12O6 6CO2 + 6H2O

Organisms Respond to Stimuli
Organisms Respond to stimuli (Temperature, Water, Food Supplies, etc.) In Order To Survive & Reproduce

Maintaining Stable Internal Environment
Keeping The Internal Environment balanced = (Homeostasis)Stable internal conditions of pH, temperature, water balance, etc.

Living Things EvolveGroups Of Organisms (Not Individuals) Change Over Time In Order To Survive Within Changing Environments.Fossil records show changes in groups of organisms
