Propagation by specialized plant parts

Propagation by specialized plant parts

Propagation by specialized plant parts

i) Rhizome: It refers to the specialized stem structure in which the main axis of the plant grows
horizontally at or just below the ground level. e.g., Bamboos, ginger, turmeric.

ii) Offset: It refers to the special type of lateral shoots or branch which develops from the main stem in certain plants and is characterized by shortened and thickened stem. e.g., Date palm, pineapple.

iii) Sucker: Sucker refers to the shoots that arise from an adventious bud or roots of a plant at below ground. E. g., Dalbergia sissoo. 

iv) Bulb: Bulb is a specialized underground organ consisting of a short, fleshy vertical stem axis bearing at its apex as a growing point. e.g., Onion, lily.

v) Corm: The swollen base of a stem axis enclosed by the dry, scale-like leaves is called as corm.
It is a solid stem structure with distinct nodes and internodes. e.g., Gladiolus, elephant yam.

vi) Tuber: It is a modified stem structure which develops below the ground as a result of swelling of the sub-apical portion of a stolen and subsequent accumulation of reserve materials. Eg, Potato, Jerusalem artichoke.

vi) Runner: Runner is a specialized stem which develops from the axis of the leaf at the crown of the plant. This grows horizontally along the ground. E.g., Mentha spp.

6) Micro propagation: Micro or in vitro propagation refers to the development of new plants from very small pieces of plants in an artificial medium under aseptic conditions.
CLIMATE CHANGE TERMINOLOGIES

CLIMATE CHANGE TERMINOLOGIES

Greenhouse Effect: 
Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This phenomenon of trapping and build-up of heat in the atmosphere (troposphere) near the Earth's surface is called the greenhouse effect and is natural and necessary to support life on Earth. Some of the heat flowing back towards space from the Earth's surface is absorbed by water vapour, carbon dioxide, ozone and several other gases in the atmosphere and then reradiated back towards the Earth's surface. If the atmospheric concentrations of these greenhouse gases rise, the average temperature of the lower atmosphere will gradually increase.

Greenhouse Gas (GHG): 
Any gas that absorbs infrared radiation in the atmosphere. Greenhouse gases include carbon dioxide (CO₂), methane (CH), nitrous oxide (N₂O), ozone (O3). chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), sulfur hexafluoride.

Global Warming: 

It refers to the recent and ongoing rise in global average temperature near Earth's surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change. However, global warming itself represents only one aspect of climate change.
