Examine the three images below. Use calculations Explain which organism would be the smallest when viewed with the naked eye. Show all the calculations you used to arrive at your answer.
\(\text{A} = \frac{4}{40} = \text{0,1}\text{ mm}\)
\(\text{B} = \frac{\text{1,6}}{100} = \text{0,016}\text{ mm}\)
\(\text{C} = \frac{\text{0,4}}{400} = \text{0,001}\text{ mm}\)
So item C would be the smallest
Tabulate four differences between animal and plant cells.
Any four of the following:
Animal Cells | Plant Cells |
Do not contain plastids. | Almost all plants cells contain plastids such chloroplasts, chromoplasts and leucoplasts. |
No cell wall. | Have a rigid cellulose cell wall in addition to the cell membrane. |
Contain centrioles. | Do not contain centrioles. |
Animals do not have plasmodesmata or pits. | Contain plasmodesmata and pits. |
Few vacuoles (if any). | Large central vacuole filled with cell sap in mature cells. |
Nucleus is generally found at the centre of the cytoplasm. | Nucleus is found near the edge of the cell. |
No intercellular spaces found between the cells. | Large intercellular air spaces found between some cells. |
