1) Frangipani Pollen:
Sample Preparation: Split a frangipani flower from the pistil to expose the androecium. Take a thin piece of tape and gently tap it. Place the tape on a glass slide.
50x: Pollen grains transparent and too small to be distinguished at this scale.
140x: Pollen grains visible yet not completely distinguishable. Elliptical and rounded shape prominent.
340x: Cells clearly visible. Elliptical, coffee-bean shape visible. Intine and exine distinguishable. Very small, transparent pollen with a prominent and darkened central ridge.
2) Leaf:
Sample Preparation: Take a thin sample of leaf from the lamina using clear tape. Attach the piece of tape on the glass slide.
50x: Distinct green pigment prominent. Smaller cells visible, yet not completely distinguishable.
140x: Cells are more distinctly visible, with a prominent green colour due to chlorophyll presence. Cell walls even more visible. Cell matrix dense and compact. Cell walls are thin. Stomata not visible.
340x: Dense cellular matrix visible. More prominent cells with moderately thickened cell walls. Cell nucleus visible and prominent. Cell structure is dense and compact. Stomata visible
