Plants having separate imperfect male and female flowers on one plant are referred to as "monoecious". When the flowers are on different plants the species is referred to as "dioecious".
Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactic acid when oxygen is lacking (fermentation).Hope it helps
