Bryophytes are non vascular plants which include, mosses, liverworts and hornworts. They are seedless and lack specialized water conducting tissues.
Vacular plants are those plants that use specialized tissues to transport food and water to all parts of the plant. They have a root system, vascular system and also a shoot system. The dominant stage of the life cycle in vascular plants is the sporophyte.
Correct answer: A). Earth’s average temperature will increase.
Green house gases are those gases, which are present in the air that have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are known to be found naturally play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
They absorb and emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But due to increased in the concentration of green house gases like carbon dioxide and methane in the environment due to pollution and deforestation is causing a great problem, which result in a global warming, which is a great concern for all the people on the planet. It will increase the annual global temperature which will result in the melting of glaciers. So, the issue of global warming should be taken seriously and adequate measure should be taken to control it.
