plants are climbers and creepers

Herbs A herb is a non-woody plant that

has green and tender stems with

few branches and is usually short

Herbs are short with tender stem

Uses

Herbs have a variety of uses

including adding flavor to food

providing medicine for diseases

and in some cases even adding a

spiritual touch

Shrubs Stem in shrubs is hard but not

very thick

have stems branching out from

the base

bull The plants with weak stem that cannot stand upright and spread on

ground are called creepers Whereas plants take support on

neighboring structures and climb up are called climbers

Leaves

Leaves are the structures which develop on branches These are greencoloured structures rich in chloroplasts As they have chlorophyll in them

they are considered to be food factories of the plant Photosynthesis occursin the leaves Each leaf bears a bud in its axil

Structure of leaf

leaf base The point of attachment of the leaf tothe node on the stem

petiole Leaf bears a stalk with which it isattached to the stem

Lamina The flat part of the leaf exposed tolight

Midrib A thin structure which extends fromthe leaf base to the tip on the lamina

Veins small thread like structures extend

from the mid rib to the leaf marginVeins helps in transportation of food

venation Arrangement of veins on the laminaof the leaf

Two types of arrangement of veins on the leaf are parallel venation and

reticulate venation

Functions of Leaf

Photosynthesis takes place in leaves in which they use carbon dioxide and

water in the presence of chlorophyll and sunlightWater comes out of leaves in the form of vapour This is called transpiration

Roots

Roots absorb water and minerals from the soil Roots are of two types-tap

root and fibrous root

Plants having the reticulate venation have tap roots while plants having the

leaves with parallel venation have fibrous roots

Flower

Flower is a reproductive structure of the plant The different parts of a flower

include sepals petals stamens and pistil Flower helps the plant to give rise

to new plants by the process of sexual reproduction

Parts of flower are

Petals The coloured parts of a flower are

called as petals

Sepals The green leaf-like parts surrounding

the bud are called the sepals

Stamens The male reproductive part of a

flower t carries pollen grains Parts

of stamen are anther and filament

pistil The female reproductive part of a

flower It carries ovules Pistil has

stigma style and ovary
