PREFACE
I am delighted to share such a valuable practice material which develops essential exam based skills. More importantly these worksheets provide convenience for students who seek something unique and wanted to work for deep understanding and implication of concepts. Based on research, inquiry and my personal experience, biological diagrams prove quite handy for inference, analysis and exploration of
concepts. As far as O Level Biology is concerned, a major proportion of assessment is based on diagrams thus; skills like labelling, identification, drawing, annotation, interpretation and analysis make a significant difference in grades even for high
achievers. Research is also evident that diagram based questions really differentiate between the guess work and the learnt concepts. In the end, I wish this resource will prove its effectiveness and will transform your learning and grades to excellence.

provide support and strength to

Development from an undifferentiated cell to a become a specialised cell First
of all
immature cells after division start to elongate and align over each other.
Secondly they get rid of their cross walls. Finally deposits of
their cell wall causes the death of cells and they become
a conti nuous col umn (capillary like structu re).
