Functions of rootas
To absorb water end dissolved mineral salts. such as calcium, phosphorus, aodium and
potassium etc. from the soil through the root (hairs.
(2) To anchor the body or a plant firmly in the
soil. This is due to the widespreading of rouAR - To act as a passage through which water and soluble salts are conducted to the stems and leaves from the regions of absorption.
In many cases the root is modified to serve other purposes, e.g.atorage, vegetative propagation and breathing.
(7) Stem hairs are
usually multicellular.
(8) Grow above the
ground surface and towards the source of light.
(9) Xylem and phicem are on same radii of the ̇plant.

Functions of stemes
(1) To serve as a passage for the conduccion of water and dissolved minerale from the roota to leaves, and of manufactured food from leaves) to other parte of the plant body
(2) To hold the leaves and flowers to the best
advantage so as to obtain-maximum amount-of- sunlight for photosynthesis and best position for pollination
(3) To act as a food-storage organ, e.g, the

rhizome, stem tuber, corm and bulb,.
(5) The stem sometimes is modified in the Toru
a tandril for climbing.
Functions of leaves:
(1) The green leaves contain chiorophyll. and can
synthesize food by the process of photosynthesis.
(2) Leaves possess stomata which serve as a
passage for the exchange of gases durin). photosynthesis and respiration.
(3) To get rid of excess water by means of
transpiration.
The leaves sometimen serve for the food-storag (e.g. the scale leaves of a bulb), and for vegetative propagation (e.g. the leaves of Begonia):
stem differs from a root as follows:
(1) Beara leaves and
flowers.

Transverse section of a dicotyledonous leat
transverse section of a Leaf shows that i tr upper and lower surfaces are protected by a one- Jayer, epidermal cells which are in turn covered with a thin cuticle. They are brick shaped and densely packed. Among them there is a number of minute pores, stomata, guarded by a pair of kidney shaped guard cells. Most of the stomata are arranged in the lower epidermis. The epidermal cells contain no chlorophyll.
In the middle part of the leaf which gain divided into two layers, the palisade tissu16 the spongy mesophyll.
The palisade tissue is the upper region containing three to four layers of cylindricu 【ce11s with many chloroplasts, The small intex-
cellular spaces: occur between the cells to store. gases from air,
The spongy mesophyll containe loosely arranged and irregular cells which contain a few chloroplasts.
Among the mesophyll tissues, veins of the leaf are embedded. They are the vascular bundles for the transportation of water and manufactured food to the: leaf or away from the leaf. Each vascular bundle is composed of xylem and phloem. The xylem cells are larger, less dense and with lass protoplasm in each cell because they are responsible for the transportation of water and soluble minerals, They face the upper part of the vascular bundle. The cells of phloem are smaller in size, densely packed, and with more protoplasm in each cell because they are responsible for the
conduction of manufactured food away from the
leat
