Write a note on complex tissues.

(N/A) $\rightarrow$ Complex tissues are made of more than one type of cells, and these cells work together as a single unit.
$\rightarrow$ These tissues are primarily associated with the transport of water, mineral substances, nutrients, and organic substances; therefore, they are also known as vascular tissues.
$\rightarrow$ In plants, the two main types of complex tissues are xylem and phloem.
$\rightarrow$ Xylem is responsible for the conduction of water and minerals from roots to the stem and leaves.
$\rightarrow$ Phloem is responsible for the translocation of food (organic substances) from leaves to other parts of the plant.
