Plant Physiology Quiz test and
answers well graded A+
protoplasm - ANS✅✅living things in a cell, doesn't include cell wall/air space
middle lamella - ANS✅✅cementing agent between cells
biomembranes - ANS✅✅membranes of lipids and proteins
transcription - ANS✅✅DNA to mRNA, occurs in the nucleus
translation - ANS✅✅mRNA used to assemble amino acids to make proteins; occurs on ribosomes,
in cytoplasm, in ER
tonoplast - ANS✅✅single, differentially permeable membrane surrounding the vacuole
pleomorphic - ANS✅✅many bodies/shapes
plastids - ANS✅✅double membrane bodies in plant cells
microbodies - ANS✅✅small, dense structures bound by a single membrane
apoplast - ANS✅✅non-living component of a cell, includes the cell wall and intercellular space
composition of cell wall - ANS✅✅cellulose, hemicellulose, lignin, pectin, extensin
cellulose chains are braided into... - ANS✅✅micelles, braided into microfibrils, braided into
macrofibrils
All plant cells have a ________ cell wall - ANS✅✅primary
, Where are primary cell walls found? - ANS✅✅young, growing, soft parenchyma cells; also
collenchyma, sclerenchyma, and fiber cells
basically all plant cells
Secondary cell wall is mostly found in _____ - ANS✅✅vascular tissue; sclerenchyma and
collenchyma
Secondary cell wall contains large amount of ______ - ANS✅✅lignin, can have multiple layers
characteristics of biomembranes - ANS✅✅thin
sheet-like
hydrophobic core
hydrophilic surface
asymmetric fluid structures
flexible, wobbly
proteins are mediators
form closed boundaries
Three membrane proteins - ANS✅✅integral, peripheral, lipid-anchored
integral protiens - ANS✅✅embedded in lipid bilayer, spans the width of the membrane, interacts
with the inside and outside of cell, acts as transporters
peripheral - ANS✅✅bound to surface through ionic/hydrogen bonds, interact with components of
cytoskeleton during cell division
lipid-anchored proteins - ANS✅✅bound to surface by linkage with lipid molecules (fatty acids)
nucleus - ANS✅✅contains cell's genetic information, directs the synthesis of all protiens, 2
membranes with 2 layers each
nuclear envelope - ANS✅✅holds nuclear content, selectively transports
