Study Notes
Introduction to Botany
- Botany is the study of plants, including their form, function, parts, classification, and diseases.
- The term "botany" originates from the Ancient Greek word "botanē", meaning "pasture", "grass", or "fodder".
- Botany is also referred to as "Plant biology".
History of Botany
- Ancient tribes possessed vast knowledge of plants, particularly regarding edible and poisonous varieties, medicinal properties, and locations.
- This knowledge was passed down through generations via oral tradition and trial and error.
- Theophrastus (370-285 BC) was considered the "Father of Botany".
- He made crude classifications of plants, categorizing them as either flowering (Phanerogams) or non-flowering (Cryptogams).
- He further classified plants into herbs, subshrubs, shrubs, and trees.
- Gaius Plinius Secundus (23-79 AD), known as "Pliny the Elder", described the biological, medicinal, and agricultural aspects of plants in his 37 volumes of "Natural History".
- He was the first to use the term "stamen".
- Padano's Dioscorides (62-128 AD), a Roman Army physician, compiled the medicinal properties of around 600 plant species in "Materia Medica".
- He introduced the names Aloe, Anemone, Phaseolus, and Arisolochia, which are still used today.
- During the Roman era, medicinal plants held great value.
- From the Middle Ages to the 17th century, plant classification was the primary focus.
- The invention of printing and advancements in navigation led to the discovery of new plant species.
- Herbals (books) and herbalists (authors) documented medicinal plants and their locations.
Characteristics of Life
- Living organisms display seven fundamental characteristics:
- Composed of cells: Cells are the basic units of life, and organisms can be single-celled (like bacteria) or multi-celled (like humans).
- Require energy: Living organisms require energy, usually in the form of ATP, to perform essential functions like metabolism and movement.
- Reproduce: Organisms reproduce to grow, sustain themselves, and create offspring similar to themselves.
- Have different levels of organization: Life exhibits a hierarchy of organization, starting with the cell (the basic unit) and extending to the biosphere, encompassing all living organisms.
- Respond to the environment: All living things react to stimuli in their environment, such as tropisms (plant growth responses).
- Grow and develop: Growth and development enable organisms to replace old and dying cells and perform different functions.
- Adapt to their environment: Adaptability enables certain individuals to thrive better than others in their environment.
Characteristics of Plants
- Plants are distinguished by several key characteristics:
- Multicellular eukaryotes: Plants are multicellular organisms with a complex cellular structure, setting them apart from their evolutionary relatives like algae.
- Photosynthesis: Plants are autotrophs, meaning they produce their own food through photosynthesis, utilizing sunlight to convert carbon dioxide and water into sugars.
- Cell walls have cellulose: Plant cell walls contain cellulose, differentiating them from fungi (like mushrooms) whose cell walls primarily comprise hemicellulose, lignin, chitin, and pectin.
-
Alternation of Generations: Plants have two adult forms that alternate in production (alternation of generations).
- Sporophyte generation: Produces spores that do not need to fuse with another to develop into a new plant.
- Gametophyte generation: Produces sperms and eggs.
- Multicellular embryo protected within the female parent: Plant embryos develop and are protected within the female parent.
Scientific Method
- The scientific method is a systematic process used to explore observations and answer questions.
- It is a tool for investigating cause-and-effect relationships in nature.
- This method involves the following steps:
- Ask a question: Start by posing a measurable question about an observation.
- Do background research: Analyze existing research to avoid repeating mistakes and find optimal approaches.
- Construct a hypothesis: Propose an educated guess about how things work, phrased in a measurable way to answer the initial question.
- Test your hypothesis through experimentation: Design a fair and controlled experiment to determine if your hypothesis is true or false.
- Analyze data and draw a conclusion: Examine the results of your experiment to determine if your hypothesis is supported or refuted.
- Communicate your results: Share your findings with others through written reports or presentations.
