PLANT CELL Flashcards
outermost part of the plant cell
cell wall
provides support to the cell and helps prevent osmotic lysis
cell wall
modified as storage organs of the plant
bulbs
encloses the living part of the cell
plasma membrane
what is the living part of the cell
cytoplasm
a eukaryotic cell that contains a true nucleus and certain organelles that perform specific functions
plant cell
organelles only found in plant cells
chloroplast, cell wall, plastids, large central vacuole
what is the plant cell wall composed of
cellulose
three layers of the cell wall
primary, secondary, and middle lamella
controls what enters and leaves the cell
cell membrane
membrane bound structure that is only present in eukaryotic cells
nucleus
stores DNA required for cell division, metabolism, and growth
nucleus
region of the nucleus responsible for producing ribosomal RNA
nucleolus
organelle responsible for producing proteins
ribosome
membrane-bound structure that contains fluids and dissolved substances
central vacuole
for storage and sustaining turgor pressure against the cell wall
central vacuole
fluid portion of the cytoplasm
cytosol
the vacuole is surrounded by
vacuolar membrane or tonoplast
elodea is an aquatic plant often called as
anacharis
one example of plastid
chloroplasts
group of organelles found in plant cells and some protists
plastids
organelle responsible for photosynthesis
chloroplast
green pigment responsible for absorbing light during photosynthesis
chlorophyll
third set of membranes forming stacks inside the outer membranes
grana
actually contains the green chlorophyll pigment
thylakoid membranes
constant flow of cytoplasm within a cell
cytoplasmic streaming
modified stems that grow underground and are used for storing starch as a food reserve for the plant
tubers
since tubers are modified for storing starch, they are composed primarily of
parenchyma cells
what can you observe in the cells of potato tuber
cells are far apart and less organized
spaces between the cell walls of adjacent cells
intercellular spaces
plastids that store complex molecules other than pigments
leucoplasts
plastids that specifically function in starch storage
amyloplasts
Channels between plant cells for transport and communication
plasmodesmata
how to calculate the size of a single cell
diameter of field/number of cells visible
transports materials throughout the cell
endoplasmic reticulum
er that makes lipids
smooth er
er that has ribosomes for protein synthesis
rough er
er that looks like trypophobia
smooth er
er that looks like lasagna pasta
rough er
gel-like substance inside the nucleus that holds the nucleolus and chromatin
nucleoplasm
Openings in the nuclear envelope that control the movement of molecules between the nucleus and cytoplasm
nuclear pores
double membrane that surrounds the nucleus
nuclear envelope
Part of the Golgi apparatus in plant cells, it processes and packages proteins and lipids
dictyosome with vesicles
liquid component of the cytoplasm
cytosol
