Question

why xylem and phloem called Complex tissue but parenchyma and collenchyma and sclerenchyma simple tissue​

Answer 1

Answer:

Xylem and Phloem are complex because they are made different cells, with different roles. Xylem is made up of tracheids, parenchyma and xylem vessels. They conduct water and minerals up, give mechanical support and store food for the the plant and plant tissue. Xylem and Phloem are together called as vascular bundles

here your answer

Answer 2

${\pink{\bf{\mathfrak{Xylem \:and \:pholem \:called \:complex\: tissue}}}}$

Xylem and Phloem are complex because they are made different cells, with different roles. Xylem is made up of tracheids, parenchyma and xylem vessels. They conduct water and minerals up, give mechanical support and store food for the the plant and plant tissue. ... Xylem and Phloem are together called as vascular bundles.

${\purple {\bf{\mathfrak{parenchyma \:and \:collemchyma \:called}}}}$

${\purple{\bf{\mathfrak{and \:sclerenchyma\: are \: called\: simple\: tissue}}}}$

The function of parenchyma cells is in the storage of foods, in gaseous exchange, and in photosynthesis, while collenchyma cells provide mechanical support and elasticity to the plant, the sclerenchyma cells provides mechanical support to the plant. It also supports transportation of water and nutrients to the plants.
