Answer:
Photosynthesis is defined as the process in which the chlorophyll-containing plant
cells synthesise food in the form of carbohydrates, using carbon dioxide and water
in the presence of solar energy.
Sources of raw materials required for photosynthesis:
(a) Water is taken in from the roots of the plant and is transported to the leaves.
(b) Carbon dioxide from the air enters the leaves through the tiny pores called
stomata .
(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is
used to synthesise (prepare) food from carbon dioxide and water.
Thus, photosynthesis can be represented by the following equation.
Explanation:
Its the first layer of protection in the atmosphere against radiation from the sun and its harmful U.V. rays.
Meiosis II the chromosomes are pulled to the center of the cell and line up randomly at the equato
Anaphase II the centromere of each chromosome splits
-the sister chromatids separate and move to opposite poles
They are all located in the body’s portion in which is in
the mediastinum. This is the central compartment that is being surrounded by
loose connective tissue in the cavity of thoracic in which these organs are
found such as the heart, esophagus and trachea.
