Overview of Botany

Overview of Botany

• Study of plant life, including their structure, growth, reproduction, metabolism, development, diseases, and evolutionary relationships.

Major Branches of Botany

1. Plant Anatomy

   • Study of internal structure of plants.
   • Involves examination of tissues and organs.

2. Plant Physiology

   • Study of plant functions and processes.
   • Includes photosynthesis, respiration, and transpiration.

3. Plant Taxonomy

   • Classification and naming of plants.
   • Hierarchical system based on similarities and differences.

4. Plant Ecology

   • Interactions of plants with their environment.
   • Role of plants in ecosystems and their adaptations.

5. Plant Pathology

   • Study of plant diseases caused by pathogens.
   • Focus on disease prevention and control.

6. Ethnobotany

   • Study of how people use plants for cultural, healthcare, and economic purposes.

Plant Structures

• Roots

  • Anchor plants and absorb water/nutrients.

• Stems

  • Support for leaves and flowers; transport nutrients and water.

• Leaves

  • Main sites for photosynthesis; optimized for light absorption.

• Flowers

  • Reproductive structures; involved in pollination and fertilization.

Photosynthesis

• Process by which green plants convert sunlight into energy.
• Involves chlorophyll, sunlight, carbon dioxide, and water to produce glucose and oxygen.

Plant Reproduction

• Asexual Reproduction

  • Cloning via runners, cuttings, tubers, etc.

• Sexual Reproduction

  • Involves seeds produced through pollination and fertilization.

Classification of Plants

• Non-vascular Plants

  • Lack specialized tissues for water/nutrient transport (e.g., mosses).

• Vascular Plants

  • Have xylem and phloem for transport (e.g., ferns, gymnosperms, angiosperms).

• Seedless vs. Seed Plants

  • Seedless include ferns; seed plants include gymnosperms (naked seeds) and angiosperms (flowering plants).

Importance of Botany

• Provides understanding of ecosystems and biodiversity.
• Crucial for agriculture, medicine, and environmental conservation.
• Contributes to the development of biofuels, food security, and protection of endangered species.

Botany Overview

• Study of plant life, from their structure and growth to how they interact with the environment, and reproduce.

Major Branches of Botany

• Plant Anatomy - internal structure of plants, examining cells, tissues, and organs.
• Plant Physiology - focuses on how plants function, including photosynthesis, respiration, and transpiration.
• Plant Taxonomy - classifies and names plants based on shared traits and differences.
• Plant Ecology - explores the relationship between plants and their surroundings, examining their roles in ecosystems and how they adapt.
• Plant Pathology - investigates plant diseases caused by various pathogens, and aims to control and prevent them.
• Ethnobotany - studies how people use plants across different cultures, including healthcare, food, and economic purposes.

Plant Structures

• Roots anchor plants in the soil, absorb water and nutrients.
• Stems support leaves and flowers, transport nutrients and water.
• Leaves are the primary site for photosynthesis, optimized to absorb sunlight.
• Flowers are the reproductive structures, responsible for pollination and fertilization.

Photosynthesis

• Process used by green plants to convert sunlight into energy, using chlorophyll, CO2, and water to produce glucose and oxygen.

Plant Reproduction

• Asexual Reproduction involves cloning through runners, cuttings, tubers, etc., producing genetically identical offspring.
• Sexual Reproduction involves seeds produced through pollination and fertilization, resulting in offspring with genetic diversity.

Classification of Plants

• Non-vascular Plants lack dedicated tissues for transporting water and nutrients, such as mosses.
• Vascular Plants have xylem and phloem for transporting these essential elements, encompassing ferns, gymnosperms, and angiosperms.
• Seedless vs. Seed Plants - Ferns are seedless, while seed plants encompass gymnosperms with naked seeds (conifers) and angiosperms with flowering plants.

Importance of Botany

• Provides understanding of ecosystems and the diversity of plant life.
• Crucial for agriculture, medicine, and environmental conservation.
• Contributes to the development of biofuels, food security, and protection of endangered species.
