26
What is plasmodesmata
breaks in the cell wall between cells
27
Leucoplasts
clear plastids that hold fats
28
parts of a non-specialized epidermal cell (3)
cell wall leucoplasts central vacuole
29
Parts of a banana cell (4)
cell wall starch grains cytoplasm striations
30
What happens to banana cells when iodine-potassium-iodine is added
they turn purple
31
Parts of a non-specialized cell / 2 cells (9)
in the epidermal cell -cell wall -plasmodesmata -central vacuole -nucleus In the Guard cells -chloroplast -cell wall -central vacuole -stoma
32
Photosynthesis formula
33
parts of a human cheek cell
plasma membrane cytoplasm nucleus
34
Why do you have to stain the cheek cell
They are clear and colourless
35
parts of an amoeba (6)
plasma membrane pseudopodium nucleus contractile vacuole food vacuole cytoplasm
36
What is the pseudopodium
protrusions/arms that help amoeba move
37
Difference between cilia and flagella
cilia are small hair-like fibers that are all over a cell flagella is one or two long tails at the end of a cell
38
What do guard cells do
open and close to allow water to come in an out to maintain pressure and not burst or dry out
39
cell wall
provides support and protection
40
central vacuole
stores water, toxins, enzymes, etc provides support while under pressure
41
chloroplast
where photosynthesis occurs
42
chromoplast
holds pigment for flowers and berries
43
cilia
help with locomotion sweep fluid around the cell
44
contractile vacuole
osmoregulation (maintain salt and water balance) in protists
45
cytoplasm
fluid region creates a place for processes in the cell
46
cytoskeleton microtubules
stops the cell from compressing provides a path for vesicle to move int he cell pull chromosomes to opposite sides when cell is dividing
47
microfilaments
Forms part of the cytoskeleton made if Actin
48
flagella
used for locomotion in algae and sperm cells
49
food vacuole
engulfs food particles in animal and animal-like protists
50
Golgi apparatus
store, modify, and ship products from the ER
51
lysosome
digest food and cell waste
52
mitchondria
does cellular respiration and makes ATP
53
nucleolus
inside the nucleus of non-dividing cells ribosomes assemble
54
nucleus
contains DNA DNA synthesis and RNA transcription
55
plasma membrane
selectively permeable
56
ribsosome
synthesizes protein
57
rough ER
initial synthesis and sorts proteins for export
58
smooth ER
lipid synthesis detox drugs and alcohol ca+2 storage glycogen breakdown
59
vesicle
may contain macromolecules for storage, transport, or secretion
60
TEM
Transmission electron microscopy A beam of electrons is transmitted through a thin section of something best shows internal structure of cells and their organelles
61
SEM
Scanning electron microscopy A beam of electrons is scanned over the surface of a specimen, making a three dimensional image of it best use for things such as insects and pollen
62
What type of electron microscopy would you use to see the hairs on the outside of a stamen flower?
Scanning
63
Which type of electrum microscopy might use to view the organelles with a liver cell
Transmission
64
Photosynthesis the process through which _____ energy is used to synthesize chemical energy in the form of _____ using _____ And _____ well releasing _____
Light Sugar Carbon dioxide Water Oxygen
65
Photosynthesis occurs in the _____ which contain the major photosynthetic pigment called _____
Chloroplast Chlorophyl
66
10 discs were placed in the barrel of a 3 mL syringe which was filled with 1 mL of__% _____ solution
2% sodium bicarbonate
67
What colour is chlorophyll? Where is it located?
Green chromoplast
68
What colour is haemoglobin and where is it found?
Red and in blood
69
What is the name of the purple pigment and where is it found?
Anthocyanin found in the vacuole
