How do conifers keep their green needles over the boreal winter?

How do conifers keep their green needles over the boreal winter? During boreal winter most trees shed their leaves. However, conifers such as Christmas trees keep their green needles intact. Scientists believe that a phenomenon called sustained quenching offers photoprotection and enables their survival, but its precise molecular and physiological mechanisms are not understood. Researchers have now found that the photosynthetic apparatus is wired in a special way which allows pin

Do plants share genetic material with each other?

Do plants share genetic material with each other? Genetic material of plants and animalsare well protected in the nucleus of each cell and store all the information that forms an organism. In addition, cells contain small organelles that contain their own genetic material.

Mangroves in India

Mangroves in India They are evergreen forests with salt tolerant trees (halophytes). They are adapted to low oxygen (anoxic) conditions of waterlogged mud. The richest Mangrove communities occur in tropical and subtropical areas i.e. Between 30 degree North and South latitudes. Where Water temperature is > 24 degrees in the warmest month. Where Annual rainfall is > 125 cm. Where Mountain 

Diversion of Fresh water from Brahmani river basin

The massive diversion of fresh water from the Brahmani river basin could pose a grave threat to Bhittarkanika mangroves vegetation in Odisha. Bhitarkanika — a notified Ramsar wetland — is spread over 195 sq. km and is home to 62 mangrove species. Besides, 1,600 salt water crocodiles crawl on the mudflats of the Bhitarkanika mangrove forest. Mangroves grow in brackish water. Proportionate fresh water flow from the Brahmani river basin and the Kharasrota river keep the salin
