1. Introduction to Secondary Growth

1. Secondary growth refers to the increase in the girth (thickness) of a plant.
2. It occurs due to the activity of lateral meristems: vascular cambium and cork cambium.
3. Mostly found in dicotyledonous plants and gymnosperms; absent in monocots.

1. Introduction

1. The stem and leaf are essential vegetative organs of plants.
2. Their internal structure helps in transport, photosynthesis, and support.
3. Both structures differ significantly in monocots and dicots.

1. Introduction

1. The root is an essential organ of a plant that anchors it and absorbs water and minerals.
2. Roots are classified into monocot and dicot roots based on their internal structure.
3. Both types share common tissue layers but differ in arrangement of vascular bundles, pith, and cortex.

1. Introduction to Permanent Tissues

1. Permanent tissue is derived from meristematic tissue and has lost its ability to divide.
2. It plays a vital role in providing support, transport, and storage in plants.
3. Permanent tissue is classified into simple and complex tissues.

2. Simple Permanent Tissue

Simple permanent tissues are made up of only one type of cell.

1. Introduction to Plant Tissues

1. A tissue is a group of cells with a common origin and function.
2. Plant tissues are classified into meristematic and permanent tissues.
3. Meristematic tissue consists of actively dividing cells responsible for plant growth.
