Why are plants important to human?
Plants provide us with food, fiber, shelter, medicine, and fuel.
plants-from three Greek words, botanikos (,(plant or herb,to feed),
botanical),botane,boskein
plant scientist or phytologist is a scientist who specializes in this field.
Botanist
Father of botany”
Theophrastus
Robert Hooke invented the microscope
1665
Stephen Hales successfully established plant physiology as a science
1727
Botany became even more widespread among educated women who painted plants, attended classes on plant classification, and collected herbarium specimens. However, their study focused on the healing properties of plants rather than plant
reproduction. Women began publishing on botanical topics, and children’s books on botany appeared (Mason 2016)
1760
Progress in the study of plant fossils was made
Early part of the nineteenth century
Chlorophyll was discovered.
1818
The two types of chlorophyll-
a and b
The two types of chlorophyll-a and b were discovered
1903
We study plants because
Plants produce oxygen. We breathe oxygen. We cannot live without oxygen.
Plants convert Carbon di oxide gas into sugars through the process of photosynthesis.
Everything we eat comes directly or indirectly from plants.
Plants provide fibers for paper or fabric. plants used as medicine.
Many chemicals produced by the
Study of plants science helps to conserve endangered plants.
Study of plants science helps to learn more about the natural world.
Characteristics of Plants
Plants are Highly Organized
Plants take in and use Energy
Plants respond to Stimuli
Plants Grow and Develop
Plants Reproduce
Plant DNA transmit information from one generation to the next
is the study of the internal (tissue and cell) structures of plant organs The term anatomy, as applied to plants, generally deals with structures that are observed under a high-powered light microscope or electron microscope.
Plant Anatomy
is the study of the physical form and external structure of plants.
Plant Morphology
Plant physiology is the study of plant functions and behaviors, encompassing all the dynamic processes of growth, metabolism, reproduction, defense, and communication that account for plants being alive
Plant Physiology
- Plant taxonomy is the science of classifying and naming plants. It is a branch of what is known as systematics, which is the science of determining how different biological organisms are related to each other. Taxonomy classifies plants and other organisms into different taxonomic levels
Plant Taxonomy
Allium Sativum-
-Garlic
Allium Cepa
Onion
Ananas Comosus
Banana
Lugarsia Esculenta
Taro Plant
the study of how and why plants are distributed where they are.
Plant Geography
ecology examines the relationships of plants with the physical and biotic environment. Plants, as sessile and photosynthetic organisms, must attain their light, water and nutrient resources directly from the environment. Light is their source of energy and it is unidirectional in origin
Plant Ecology-Plant
is the art and science of changing the traits of plants in order to product desired characteristics.”-Sleper and Poehlman, Breeding Field Crops, 1995. Plants are crossbred to introduce traits/genes from one variety or line into a new genetic background. For example, a mildew-resistant pea may be crossed with a high- yielding but susceptible pea, the goal of the cross being to introduce mildew resistance without losing the high-yield characteristics.
