Life Vocabulary: (main section) Biology - The study of life Biotic - living Abiotic - non-living Cell - basic unit of life Sexual Reproduction - process in which genetic material from two
parents combines and produces offspring that differ genetically from either parent
Asexual Reproduction - process by which a single parent reproduces by itself
Growth - increase in size Development - The process of change that occurs during an organism's
life to produce a more complex organism. Differentiation - change in structure and function of a cell as it matures;
specialization Metabolism - all of the chemical reactions that occur within an organism Homeostasis - Process by which organisms maintain a relatively stable
internal environment Evolution - the process by which species gradually change over time Organism - A living thing --has all eight characteristics of life
5 topics that we will cover this year
1. Introduction to science. (inquiry)
2. Life science
3. Physical Science
4. Chemistry
5. Earth Science
What is LIFE?
Biology
Biology – break it into root words?????
Biology
Biology – study of life
Is fire alive?
Leave some space, come back at the end and try to answer this.
Six characteristics of life:
1.Composed of cells2.Living things reproduce3.Grow and develop4.Use and obtain energy5.Respond to their environment6.Homeostasis
Scientist are sceptics
• A sceptic - someone who questions something. • fact checker, not ignoramus
• So, who decided what life is?• Is it an accurate system?• Is it possible that life is something different than what
we define it as?
1. Living things are composed of cells All living things
have cells
1. Living things are composed of cells All living things
have cells
Cells are never formed by non-living things
2. Living things reproduce
All living things die, so reproduction is necessary
2 types Sexual - two cells
from different individuals unite to produce new cell (new individual)
2. Living things reproduce
Asexual - single organism reproduces without the aid of another.
More simple - some organisms simply divide in two.
3. Living things grow and develop All living things
are capable of growth
4. Living things use and obtain energy
Living things obtain energy from their environment.
Different types??
4. Living things use and obtain energy
Photosynthesis - plant energy from sun
Metabolism - energy from food
Chemosynthesis - energy from chemical sources
5. Living things respond to their environment Can be fast (behavior), or
slow (metabolism or growth)
5. Living things respond to their environment Can be fast (behavior), or
slow (metabolism or growth) Cause of change called
stimulus
5. Living things respond to their environment Can be fast (behavior), or
slow (metabolism or growth) Cause of change called
stimulus Living things respond in
ways that improve chances of survival
6. Homeostasis
The processes by which organisms respond to stimuli in ways that keep their body suitable for life
Examples in humans?
Book: Chemicals of life.
6. Homeostasis
The processes by which organisms respond to stimuli in ways that keep their body suitable for life
Humans: warm blooded, sweat, shivering, sickness, waste excretion, etc.
Date: Is your car alive?
Entry question; please use the 6 characteristics of life and tell me if a car is alive. Please write a good response. Defend your answer.
Is your car alive?
1.made of cells?
2.reproduce?
