1 Problem №7 “Growing through asphalt”

2 Text of the problem: Can a little plant grow straight up through concrete or asphalt?

3 Aims of the problem: Can plants grow through asphalt
Find out conditions of growing plants through asphalt

4 Asphalt

5 Concrete

6 Turgor Еxternal environment Cell’s protoplasm. Water with solutes
Cell membrane is tough, inextensible, semi-permeable membrane Cell’s protoplasm. Water with solutes Turgor is occurred because of inextensible cell membrane. Water is come into cell because of osmosis Pосм – osmosis pressure

7 Observed frequents

8 Observed frequents

9 Observed frequents

10 Experiment

11 Experiment We have used peanut sprouts to know which mass plants can lift

12 Growing of seeds First day

13 Growing of seeds

14 Conclusion: Plants can’t grow through asphalt and concrete if there are no cracks in these materials

Cell Membranes (both) Thin, flexible barrier The cell membrane is a lipid bilayer. It is also semi- permeable which means that it only lets in some materials.
