Theory

Answer and comment to theory

6

Publish

Laws are concepts that have been accepted by the public.

7

Steps according to life biologically

Respond
Organize
Homeostasis
Metabolism
Produce Waste
Reproduce
Evolve
Made of water and carbon

8

Life needs to be organized
Atoms
Molecules
Us
Life or death

Organization

9

All biochemical reactions occurring in a cell
Everything cycles
Molecules of energy
Uses ATP
life or death

Metabolism

10

Steady, level, balance,
Body temp
Life or death

Homeostasis

11

Organism respond to environment
Movement muscle
Life and death

Respond

12

Life and death
Pee-cleanse body
Poop isn't waste
Breathing co2

Produce waste

13

Not life or death
Sexy is important
Grown born little get big

Reproduce (growth)

14

Change
99% of all liking things are extinct
Man made
Environmental
Not life or death

Evolve

15

Life And death
80% of water
Car born organizes water into life

Life is made of carbon and water

16

Some never have 8 characteristics
Failed at all 8
Last cell dies that's when your dead

Nonliving

17

Materials that are Nonliving

Water
Rocks
Air
Metal
Glass

18

Smallest unit of life

Cell

19

Who discover cells and how

Robert hook
Looked at a cork through a microscope

20

Two cell theory parts

All organisms made of one or more cells

All life comes from pre existing life

21

Sperm and egg
Where'd first cell come from
Spontaneous generation

All life comes from pre existing life

22

Usually small
Ostrich Eggs are biggest
Because of transport

Cell sizes

23

Cells must transport

Inhabiting determined size of cell

24

Anabolic

Building

25

Catabolic

Breaking

26

Prokaryotic

Bacteria simple

27

Eukaryotic

Plants animals and fungi
Complex

28

Four minimum cell parts

Membrane
Cytoplasm
DNA
Ribosomes

29

Surface and internal
Edge of life
Cite of transport

Membrane

30

Water based material and makes up the rest of the cell.
Bulk of cell.

Cytoplasm

31

Stores info and runs cells

DNA

32

Makes protein
Proteins are made of amino acids
All enzymes are proteins
All metabolisms require enzymes

Ribosomes

33

Prokaryotic (bacteria)

Membrane
Cytoplasm
DNA
Ribosomes
Cell wall
Capsule
Pili
Flagella

34

Three shapes of bacteria

Round
Rod
Spiral

35

Support and protects
Ex clothes over skin

Cell wall

36

Slimy toxic coating
Found in some not all

Capsule

37

Short extensions off surface used as anchors
Found in some

Pili

38

Movement
Some

Flagella

39

1. Divides into two identical cells

2. Grow apart

3. Pinch in the middle

Binary fission

40

Sore and transfer info
Control cell metabolism

Nucleus

41

Transport material out of nucleus

Pores

42

Water based

Nucleoplasm

43

Makes RNA

Nucleolus

44

Relaxed DNA

Chromatin

45

Chromosomes

Transport

46

Makes protein

Ribosomes

47

Taxi goes anywhere
Can turn into microbodies
Named by context

Golgi

48

Energy organelles

Chloroplast
Mitochondria

49

Series of protein tubes for support transport organization of the cell

Cytoskeleton

50

Most organisms and made of sugar and cellulose.

Cell wall

51

Long and few

Flagella

52

Short and many

Cilia

53

All cells have this
Allowing or not allowing things and organization

Membrane

54

Fat called in lipid
Keeps waste out and in
Like dissolves like

Phospholipid

55

Part of normal setup
Transport
Proteins are there to let things in that aren't supposed to be in

Proteins

56

Structural
Cel lent

Cholesterol

57

Surface markers

Body defense
Blood type
Organ transplants
Auto immune disease
Cancer

58

Conditions where you've lost your ability to tell yourself
Ex rum atomic arthritis

Auto immune disease

59

Uncontrolled cell division
Blind cells
Contact inhibition
cell feels itself and doesn't divide
Tumor doesn't make you malignant

Cancer

60

Transport

Passive
Active

61

Follow gradient
High to low concentration
Doesn't use ATP
absolute 0 molecules stop moving

Passive

62

Movement of molecules from high to low till you hit an equilibrium.

Diffusion

63

Movement of water from its high concentration to lower concentration through a membrane until equalibrium

Osmosis

64

Low to high
Uses ATP

Active

65

Constant pumping sodium out against gradient
Use ATP a lot

Sodium potassium pump
