Explore the Fascinating World of Plant Physiology

• Plant physiology is a subdiscipline of botany that studies the functioning of plants.
• It includes the study of processes such as photosynthesis, respiration, plant nutrition, and plant hormone functions.
• Plant physiology also covers the study of interactions between cells, tissues, and organs within a plant.
• The field encompasses the study of plant response to environmental conditions and their variation.
• Phytochemistry is a major subdiscipline of plant physiology that studies the biochemistry of plants.
• Plants produce a wide array of chemical compounds not found in other organisms to function and survive.
• Pigments are important molecules for plant function, including chlorophyll, carotenoids, anthocyanins, and betalains.
• Plants produce hormones and other signaling molecules to regulate their internal functions.
• Plants require nutrients, such as carbon and nitrogen, in large quantities to survive.
• Micronutrients are required only in trace amounts for plants to remain healthy.
• Plant hormones or plant growth regulators (PGRs) regulate a plant's growth and development.
• Plants lack specific hormone-producing tissues or organs.
• Plant hormones are vital to plant growth, affecting processes from flowering to seed development, dormancy, and germination.
• The most important plant hormones are abscissic acid (ABA), auxins, ethylene, gibberellins, and cytokinins.
• Plants use photoreceptors, including phytochrome and cryptochrome, to sense light and control structural development (photomorphogenesis).
• Many flowering plants use the pigment phytochrome to sense seasonal changes in day length, which they take as signals to flower (photoperiodism).
• Environmental physiology deals with the ways in which plants respond to their environment, including physical and biological factors.
• Tropisms and nastic movements are plant responses to directional and non-directional stimuli, respectively.
• Phytopathology is the study of diseases in plants and the manner in which plants resist or cope with infection.
• Bordeaux mixture was the first known fungicide, discovered in the nineteenth century.
• Bacon concluded soil was only needed to keep a plant upright.
• Van Helmont's experiment showed plants get their weight from water, not soil.
• John Woodward found plants grew better in water with soil added than in distilled water.
• Stephen Hales is considered the Father of Plant Physiology for his experiments.
• Julius von Sachs unified plant physiology and made it a discipline.
• Plants absorb essential mineral nutrients as inorganic ions in water.
• Soil is not essential to plant growth, hydroponics can be used instead.
• Plant physiology is important for food production and crop physiology.
• Topics studied include climatic requirements, nutrition, and optimal planting and harvesting times.
• Crop physiology looks at how plants respond to each other to maximize food production.
