Roots anchoring plants in the soil absorbing water and nutrients from the soil, a means of vegetative propagation. Stems supporting leaves, flowers and fruit providing a pathway for movement of substances between the roots and the leaves (translocation) storage of food substances. photosynthesis within herbaceous stems, a means of vegetative pro...View PDF
Botany plant growth terms are Adventitious Roots, Auxillary Bud, Aventitious Root Formation, Internode, Leaf, Node, Nucrotic Plate and Parenchyma Cells (lallus). ...View PDF
When the seed germinates, the embryonic root or radicle extends by the division and elongation’s of its cell to form the primary root. Tap root systems develop from only one enlarged primary root, which then forms lateral or secondary roots. Fibrous root systems consists of not only one radicle, but also several additional embryonic roots called ...View PDF

A leaf is a lateral outgrowth from a stem, arises at a node and possesses a bud in its axil. Functions of leaves Photosynthesis, Transpiration. Leaves have wide variat...View PDF
A leaf is a lateral outgrowth of a stem, arising at a node and possessing a bud in its axil. Most leaves have a flattened and expanded lamina (leaf blade) that possesses the green pigment chlorophyll. Fruit is produced following flowering and pollination. Fruit contains seeds, each seed giving rise to a new plant. These structures are highly modifi...View PDF
