15 Structure of Fruits & Veggies Flashcards
what is the plasmalemma?
semi-permeable membrane that monitors plant-water relationship. responsible for turgidity
what’s the vacuole?
- fluid reservoir of cell
what is cytoplasm?
is a jelly like fluid matrix of complex macromolecules. site of major metabolic activities
what’s the plasmadesma?
communicates with adjoining cells
what’s the nucleus?
overall control of all metabolic activities, esp protein synth, and genetic code transformation
what’s the nucleolus?
largest organelle in nucleus; responsible for ribose biosynthestis
what’s the ribosome?
contains the RNA-rich organelle responsible for protein synth
what’s a chromoplast?
imparts color
what’s the golgi complex?
implicated in cell wall synthesis. also modification and transportation of proteins and fats built in ER
what’s the endoplasmic reticulum?
responsible for synth and transport of many components for use inside and outside of cell; provides pipeline between nucleus and cytoplasm
what’s dermal tissue?
protective tissue; facilitates gas exchange
- loss of moisture
- pathogen/chem invasion
- mech injuries
- temp stresses
- volatilization of aromatic compounds
- texture loss
what are epidermal cells?
- outermost layer of organ
- cell walls are impregnated with lipi-like material
what’s the cuticle?
- dermal membrane
- water-impermeable surface layer; cutinization dictates the functional properties
- CUTIN (polymerized product of hydroxycarboxylic acids and their esters)
- WAX (ester of aliphatic wax alcohols and their FAs)
which has more wax/cutin: fruits or veggies?
fruits
