Q

How were plant and animal cells created

A

plant- engulfed prokaryotic cell which went through chloroplast

animal- engulfed cyanobacteria -> mitochondria -> double membrane different than DNA found in nucleus

25
magnification:
making an image appear larger
26
resolution:
ability to distinguish between two objects
27
light microscope:
uses light in order to see an image (dark image on a light background)
28
electron microscope:
uses electron beams in order to see an image
29
types of electron microscopes
TEM: most ideal for seeing structures SEM: most ideal for seeing in 3d
30
total magnification
eye peice multiplied by object lense
31
ribosome:
complex organelles used to translate coded instructions of mRNA molecules
32
cytoplasm
the material or protoplasm within a living cell, excluding the nucleus.
33
membrane bound organelles
Eukaryotic cells are cells with membrane bound organelles such as a nucleus, mitochondria, endoplasmic reticulum, vacuoles, and Golgi apparatus. A membrane bound organelle is an organelle that is surrounded by a phospholipid bilayer.
34
Protists
protists are a diverse group of organisms that are mostly aquatic and unicellular (made of a single cell).
35
Be able to identify the parts of a microscope
- eye peice - arm -ocular lense -slide clip -stage -diaphragm x2 - base - power switch -adjusting knobs a) course adjustment (faster, more) b) fine adjustment (smaller distance slower)
36
What are the three types of bacterial cells?
spirillum, coccus, bacillus
37
Word part- meanings: pro- =nucleus or kernal eu-
=before -karyon =true
38
Amoeba:
a type of cell or unicellular organism with the ability to alter its shape
39
Cell membrane:
only lets certain molecules in and out (maintains homeostasis), keeps cells stable
40
Cytoplasm:
surrounds all internal cell structures
41
Cytoskeleton:
surrounds all internal cells structures
42
RIbosomes:
are not membrane bound organelles. in both Eu and pro karyotes. make protein, can be attached to rough endoplasmic reticulum
43
Nucleus
powerhouse of the cells, hold genetic material, controls cells activities
44
Nucleolus:
inside of a nucleus, where ribosomes are produced
45
rough Endoplasmic reticulum
has ribosomes attached to it, involved with protein producing and transportation
46
Endoplasmic reticulum:
highly involved with the transporting of molecules
47
Smooth endoplasmic reticulum (S.E.R)
detoxifies (liver has a lot of these) can made types of lipids
48
Golgi apparatus:
receive items, can modify molecules, and store molecules. Determines where to send these molecules (sent to the membrane to be secreted)
49
Mitochondria:
powers plants, makes ATB energy in cellular respiration. Runs on glucose and oxygen to make ATB efficiently
50
Vacuoles:
storages of materials Usually- Animals: small and multiple Plants: large and singular
51
Chloroplast:
makes glucose by using light energy (photosynthesis)
52
Cell wall:
plants have this for extra protection
53
How to be secreted if you were a proteins cell:
1) get instructions to be made 2) get made in a rough endoplasmic reticulum 3) get shipped off by E.R to the golgi apparatus 4) get marked to be secreted by golgi apparatus 5) get shipped to cell membrane and become secreted
54
what is the monomer of carbohydrates
monosaccarides
55
what is the monomer of proteins
amino acids
56
what is the monomer of lipids
fatty acids glycerol
57
58
what is the monomer for nucleic acid
nucleotides
59
what binds glucose and fructose and what does that make and what class are those two sugars found in
glycosidic bond (sugars joining) creates sucrose and h20 carbohydrates
60
if you combine amino acid 1 and 2 what binds them together and what do you create what class are they in
peptide bond (amino acids joining) dipeptide and h20 proteins
61
if you combine monoglyceride and a fatty acid what binds them and what is created? what class are they in
ester bond(fatty acid joining to glycerol) diglyceride and h20 lipids
62
What is it called when in biochemical reactions you get a product that includes H20
dehydration synthesis
63
what are the 4 classes of carbon based molecules? What do these things do
lipids, carbohydrates, proteins, nucleic acids lipids- store long-term energy carbs- store short term energy proteins- muscle development and immune health nucleic acids- dna rna coding of traits
64
What is an enzyme?
build/ break things down
65
What is it called when you take a enzyme out of its prefered temp or pH
denaturing
66
study quiz 1 more in depth
67
know all the functions of organelles/ structure in animal and plant cells as well as prokaryotes
write these down and check notebook
