THE PROBLEM AND REVIEW OF RELATED LITERATURE AND STUDIES Introduction Everyone is naturally pre-determined to have an offspring. This would just exist in a relationship of a man and woman. It is not always true in a relationship if there is a new life that will be formed. Several factors may contribute to the hindrances in the formation of new life especially to man because male (sperm) gamete is the one responsible to initiate fertilization‚ the union of male (sperm) and female (ovum) gametes

Four theories have been proposed for the mechanism of citric acid formation by Aspergillus niger.It would appear that metabolic shunt(induced by environment) is at work‚ since citric acid is usually not a metabolite that accumulates in the medium but is readily utilized as a carbon source. The culture conditions are minimal for nitrogen and carbon at low pH. Phosphate is usually deficient. Aspergillus niger appears to have more than one systems for the formation

The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients from the soil. In addition‚ roots often form mycorrhizae with fungi‚ providing further advantage. Some roots are specially designed to store nutrients for later use of the plant. Leaves are wide flat regions that grow off of the stem. Their primary purpose is to add surface area for photosynthesis. 2. List the
