enzymatic activity is affected by
PH, tempature, and regulatory molocules
25
positively charges molocules
protons
26
photosythesis
uses sunlight to convert to energy
27
cells are
the basic unit of life
28
explain cell theory
all cells come from previous cells. cells basic unit of life all living things are made up of cells.
29
thin flexiable barrier of a cell
cell mambrane
30
the nucleous stores
genetic materal
31
prokyeriote vs eukaryote
eukaryote has nucleous and prokyote doesnt
32
organelles means
little organs
33
vacuouls do what
store shit
34
lyosomes do what
breaksdown shit
35
cytoskeleton is for
to keep cell in shape and involved in movement
36
golgi appartus
modifies, sorts, and packages
37
mitochnadria is the
powerhouse of cell
38
lipid bilayer
forms strong flexiable layer
39
selective permiable
only allows certain shit to enter and exit
40
diffusion
high concentration to low concentration
41
facilitated diffusion
diffused through special channels
42
aquaporins
only water passes through them
43
osmosis
diffusion of water through selective permeable membrane
44
iso hypo hyper tonic
equal below over or exessive strength
45
active transport is
needs energy for it to transfer
46
homeostasis
constant internal and chemical
47
Which organic molocules is formed by strings of Amino Acids
Proteins
48
Function of nucleic acids
Help transmit genetic information
49
Water has the ability to keep constant tempatures even if the weather is not constant, why is this important
Many aquatic animals can't survive rapid weather changes
50
``` All cells have A.nucleous B.cell wall C.chloroplast D. Cell membrane ```
D. Cell membrane
51
How does DNA differ from Prokyotes vs. Eukyotes
Pro. Has it suspended in cytoplasm and Euk. Has it stored in nucleous
52
Ways to differentiate plant cell from animal cell
Only plants have a cell wall and large central vacuole. | Animal plants doesn't
53
Organellses involved in energy conversion
Mitochondria and chloroplast
54
Function of cell membrane
Regulate things in and out of cell
55
Channels and pumps of a cell are made up of

57
Led to development of cell theory
Controlled experiments
58
All cells have a
