When a candle burns, both physical and chemical changes occur. ... So, the melting of wax and vapourisation of melted wax are physical changes. Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light.
When a candle burns, the oxygen in the air reacts and forms carbon dioxide. A new substance, the CO2 is formed. So it is a chemical change. When the candle melts, no new substance is formed and the molten wax can be again solidified and made into a candle and it is a reversible change.

The tracheids are most useful in the gymnosperms where elements need to be transported.

Identifying a tracheid in a cross section is quire easy as the tracheid cells fit into each other neatly and piled up similarly and have identical shapes as well which makes them obvious from other cells.              

The two examples of tracheid plans could be

On which side of a selectively permeable membrane does osmosis exert a pressure
bixtya [17]
It is the Hypertonic Side. Osmosis applies a weight known as osmotic weight on the hypertonic side of a specifically porous film. 
This implies osmotic weight should deliver a net development of water into a run of the mill cell that is encompassed by new water. On the off chance that that happens, the volume of a cell will increment until the point when the cell ends up plainly swollen. In the end, the cell may blast like an overinflated expand.
