Fill in the Blanks

Carl Linnaeus is known as the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

Father of Taxonomy

The Great Banyan tree is famous for being the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ tree present in Kolkata Botanical Garden.

widest

Plants such as mosses, ferns, and algae are called ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ plants.

non-flowering

A leaf is attached to the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ of a stem or its branches.

node

The stalk of a leaf is called the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

petiole

The green, flat, and expanded part of the leaf is known as the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

lamina or leaf blade

Leaves without a petiole are called ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ leaves.

sessile

In reticulate venation, veins and veinlets form a ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ in the lamina.

network

Leaves of monocot plants typically have ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ venation.

parallel

In a simple leaf, the lamina is ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

undivided

A compound leaf is a group of leaflets attached to a common stalk called the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

rachis

The green pigment in leaves that traps sunlight energy is called ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

chlorophyll

During photosynthesis, leaves use carbon dioxide and give out ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

oxygen

The process of removal of excess water from the surface of leaves in the form of water vapour is called ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

transpiration

Exchange of respiratory gases in plants takes place through tiny pores called ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

stomata

Food made by leaves is initially in the form of ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ and stored as ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

glucose, starch

In plants with weak stems like Pea, leaves are modified into ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ for support.

leaf tendrils

In Cacti, leaves are modified into ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ to avoid loss of water by transpiration.

spines

‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ leaves protect the buds and can store food material in plants like Ginger and Onion.

Scale

Insectivorous plants supplement their ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ requirement by preying on insects.

nitrogen

The lamina of a Pitcher plant is modified into a ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

pitcher

In Venus flytrap, the lamina is divided into two parts with ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ margins.

toothed

New Bryophyllum plants can grow from ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’ present along the leaf margin.

adventitious buds

The section of a plant stem between two nodes is called an ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.

internode

The swollen end of the petiole, where it attaches to the stem, is called the ‘_ _ _ _ _ _ _ _ _ _ _ _ _ _’.
