Study Notes
Botany
Definition and Scope
- Botany is the scientific study of plants, including their structure, growth, evolution, classification, and distribution.
- It encompasses various aspects of plant biology, including morphology, anatomy, physiology, biochemistry, and ecology.
Branches of Botany
- Plant morphology: study of the external form and structure of plants.
- Plant anatomy: study of the internal structure of plants.
- Plant physiology: study of the functions and processes that occur within plants.
- Plant ecology: study of the interactions between plants and their environment.
- Plant systematics: study of the classification, identification, and naming of plants.
- Ethnobotany: study of the use of plants by humans, including their cultural and traditional significance.
Plant Cell Structure
- Cell wall: rigid outer layer composed of cellulose, hemicellulose, and pectin.
- Plasma membrane: semi-permeable membrane that regulates the movement of substances in and out of the cell.
- Cytoplasm: jelly-like substance inside the cell where metabolic reactions occur.
- Chloroplasts: organelles responsible for photosynthesis.
- Vacuoles: organelles involved in storage, recycling, and waste management.
Plant Growth and Development
- Seed germination: process by which a seed begins to grow into a new plant.
- Meristems: regions of undifferentiated cells that give rise to new tissues and organs.
- Hormones: chemical messengers that regulate plant growth and development.
- Tropisms: growth responses to environmental stimuli, such as light and gravity.
Plant Reproduction
- Flowers: reproductive structures that produce gametes (sperm and egg cells).
- Pollination: transfer of pollen from one plant to another, allowing for fertilization.
- Fruits and seeds: structures that develop from fertilized flowers, containing the next generation of plants.
Plant Responses to Environment
- Photosynthesis: process by which plants convert light energy into chemical energy.
- Transpiration: process by which plants release water vapor into the air.
- Stomata: small openings on the surface of leaves that regulate gas exchange.
- Plant defense mechanisms: strategies used by plants to defend against pathogens, herbivores, and environmental stressors.

Botany
- Botany is the scientific study of plants, including their structure, growth, evolution, classification, and distribution, also known as plant biology or phytology.
Branches of Botany
- Structural Botany involves the study of plant structure, including morphology, anatomy, and cytology.
- Systematic Botany involves the study of plant classification, identification, and naming.
- Ecological Botany involves the study of plant interactions with their environment and other organisms.
- Physiological Botany involves the study of plant functions, such as photosynthesis, respiration, and metabolism.
- Genetic Botany involves the study of plant genetics, including genetic variation, inheritance, and evolution.
Plant Structure
- Roots are underground organs that absorb water and nutrients.
- Stems are above-ground organs that support leaves and transport materials.
- Leaves are organs that carry out photosynthesis.
- Flowers are reproductive structures that produce seeds and fruits.
Plant Classification
- Plants belong to the domain Eukarya (eukaryotic organisms).
- Plants belong to the kingdom Plantae (plants).
- Divisions of plants include Bryophyta (mosses), Pteridophyta (ferns), Gymnospermae (gymnosperms), and Angiospermae (angiosperms).
Importance of Botany
- Plants provide food, fiber, and other essential resources.
- Plants are a source of medicinal compounds and traditional remedies.
- Plants play a crucial role in regulating the Earth's climate and ecosystems.
