Study Set Content:
All of the cellular components between the plasma membrane and nucleus
Cytoplasm
Souplike fluid in the cytoplasm in which organelles are dispersed
Cytosol
Persistent structures with specialized functions
Organelles
First structure discovered by Hooke and defines the shape of the cell
Cell Wall
form a thin layer on all plant organs
Epidermal cells
specialized in their function of photosynthesis
Thin-walled cells
help transport water
Thick-walled cells
Main structural component of the cell wall and is the most abundant polymer on the earth
Cellulose
gluelike substances that holds cellulose fibrils together
hemicellulose
organic material that gives stiffness to jellies
Pectin
Proteins that have sugars associated with their molecules
Glycoproteins
first produced when new cell walls are formed
Middle lamella
Are derived from primary walls
Secondary walls
Strands of cytoplasm that extend between the cells
Plasmodesmata
Majority of cells in a plant, Found in leaves and carry out photosynthesis and cellular respiration, stores starches
Parenchyma Cells
Provide support to a growing parts of the plant and grows and change shape as plant grows
Collenchyma cells
Hard cells, dead very thick cell walls
Sclerenchyma cells
xylem cells
transport mostly water cells
transport mostly starch and nutrients
Phloem cells
Physical boundary that confines the contents of the cell to an internal component
Plasma Membrane
