31
endoplasmic reticulum
producer of protiens rough or smooth
32
ribosomes
biological protien sunthesis machines
33
golgi apparatus
pita looking, transports and sorts protiens
34
plastids

40
intercalary meristem
isolated, dividing regions near leaf bases (grasses)
41
subapical meristem
rapidly elongated region of flowering shoot of normally rosetted plants (beets, radish, lettuce)
42
parenchyma
