1. Introduction to Flowers

1. A flower is the reproductive organ of angiosperms.
2. It is responsible for sexual reproduction and produces seeds.
3. Flowers can be unisexual (having either stamens or carpels) or bisexual (having both stamens and carpels).

1. Introduction

1. The flower is the reproductive organ of angiosperms.
2. It consists of four main parts: sepals, petals, stamens, and pistil.
3. The arrangement of flowers on a plant is called inflorescence.

1. Introduction

1. The leaf is a lateral, flattened structure of the plant, mainly responsible for photosynthesis.
2. It is typically green due to the presence of chlorophyll.
3. Leaves arise from the nodes of the stem and are arranged in a specific manner.
4. Their main functions include photosynthesis, transpiration, gas exchange, and storage.

1. Introduction

1. The stem is the main axis of the plant that bears leaves, flowers, and fruits.
2. It helps in support, conduction, and storage of nutrients.
3. Stems can be modified to perform specialized functions like storage, reproduction, and perennation.
4. Based on their modifications, stems are categorized into different types.
