Answer:

1) Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don't get a chance to grow and cause disease.

2) All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions. Once inside a cell, viruses have genes for usurping the cell's energy-generating and protein-synthesizing systems.

3) A flower having sepals, petals, stamens, and pistils is complete; lacking one or more of such structures, it is said to be incomplete.

4) Rice, wheat, maize all have one cotyledon in their seed, so they are monocots.

5) A pea is a dicotyledonous plant, the seed (the pea itself) has two halves, cotyledons

6) Fungi cause decay by releasing enzymes onto the dead animal or plant. These break down complex compounds into simple soluble ones that can be absorbed by decomposers. Organisms that feed on dead material in this way are called saprophytes.
