What are the 7 properties of life

Order
Reproduction
Energy processing
Growth
Regulation
Response to environment
evolutionary adaptation

2

what are the 11 hierarchal organizations of life

biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell, organelle, molecule

3

Biosphere

all environments on earth that support life

4

ecosystem

all organisms in a particular area and physical components with which they interact

5

community

entire array of organisms living in an ecosystem

6

population

all the individuals of a particular species living in a population

7

organism

an individual living thing

8

organ system

several that cooperate in a specific function

9

organ

a structure that is composed of tissues

10

tissue

a group of similar cells that preform a specific function

11

cell

the fundamental unit of life

12

organelle

a membrane-enclosed structure that preforms a specific function within a cell

13

molecule

cluster of atoms held together by chemical bonds

14

what are emergent properties

props that arise in each step upward in the hiearchal level from the arrangement and interaction of component parts

15

what are characteristics of all cells

they are enclosed by a membrane that regulates passage of materials between it and its surrounds. and use DNA as their genetic information

16

what are the two types of cells

prokaryotic, eukaryotic

17

what are characteristics of prokaryotic cells

First- first to evolve
Simpler
Small- are usually smaller than eukaryotic cells

18

what are the charactersistics of eukaryotic cells

found in plants, animals, fungi, protists, contain membranes and organelles

19

what are the 3 main players in energy flow in ecosystems

producers-plants
consumer-animals
decomposers- fungi- change plants and animals into simpler chemicals that plants can absorb and use
