2/ what is the role of pollen in a plant's life cycle?

3/ Find a prepared slide containing pollen tubes. Sketch a pollen grain with pollen tube. State the total magnification of the drawing. Estimate the size of the pollen tube. Then compare and contrast the physical structure of male and female cones ( record observation ).
