The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. [25] NASA predicts that space stations or space colonies will one day rely on plants for life support. [26] Scientific advances in genetic engineering led to developments in crops.
The best example is the Yoda Ela or Jaya Ganga, an 87 kilometres (54 mi) long water canal carrying excess water between two artificial reservoirs with a gradient of 10 to 20 cm per kilometer during the fifth century AD. However, the ancient engineering methods in calculating the exact elevation between the two reservoirs and the exact gradient ...
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist, plant scientist or phytologist is a scientist who specialises in this field.
Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [7] Emergence of variants of the same species may occur in the same geographical region where different habitats provide distinct ecological niches for these organisms examples of these habitats include ...
The relationships between plant groups are still being worked out, and the names given to them vary considerably. The clade Viridiplantae encompasses a group of organisms that have cellulose in their cell walls, possess chlorophylls a and b and have plastids bound by only two membranes that are capable of photosynthesis and of storing starch.
Solow [4] showed that, given a degree of substitutability between human capital and natural capital, one way to design a sustainable consumption program for an economy is to accumulate man-made capital. When this accumulation is sufficiently rapid the effect from the shrinking exhaustible resource stock is countered by the services from the ...
P is your principal balance you invested. R is the annual interest rate expressed as a decimal. N is the number of compounding periods in a year. T is the time periods to calculate in years.
Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1] It is used to improve the quality of plant products for use by humans and animals. [2] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.
