parenchyma
cellulose
photosynthesis, storage and secretion

mechanical support
collenchyma in
growing parts of plants such as young stem
and petiole of a leaf
sclerenchyma present in
fruit walls of nuts
pulp of fruits of guava, pear and sapota
seed coats of legumes
leaves of tea
xylem
tracheids
vessels
xylem fibres
xylem parenchyma
gymnosperms
lack vessels in their xylem
main water transporting elements in flowering plants
tracheids and vessels
ray parenchymatous cells
radial conduction of water
xylem in stem
endarch
protoxylem > metaxylem
