Cell Structure Flashcards
What mades plant cells different from animal cells
cell wall
chloroplasts
vacuoles
Are cell walls rectangular
some
DOes soil fertility affect cell structure and funciton
yes
Environmental stress impacts cell structure and function how?
○ Drought- less turgot pressure = less SA = less transporation = plant survives = less yield
Function of cell membrane
Regulate passage of molecules in and out of cell and organelles
2 layers of membrane
Hydrophillic head and hydrophobic tails
Wether something is hydrophilic has to do with polarity
true
Protiens
molecules that form structures and execute cell work
Facilitated diffusion
protiens create channels for molecules like ions
Active transport
molecular pumps- binds to molecules and lets out the other side
CELL WALL PIC MEMORIZE
-NO WORDBANK
TF the plasma membrane is included in the cell wall
f
What is the cell wall amde out of
sugar and protiens
Cell wall functions
structure
defense and immunology
stress response
gene expression
cell to cell communication
TF cell wall controlls plant growth
T- how fast which direction resisting turgor pressure in cell
What is middle lamella made up of
pectin
what is secondary cell wall made up of
lignin
dO ALL cells have seconday cell wall
no- only older plant produce this
Do cell walls change over time
yes
Protoplast
cell that has its cell wall removed
Protoplasm
stuff inside cell
Protoplasm + vacuole =
protoplast
Plasmodesmata
small holes in the cell wall that allow for cell to cell communication
Vacuole
Stores extra nutrients- plants cant poop
Apoptosis
Stores pigments
Turgor pressure
Filled w protien for germinating seeds
