9.3 - Growth in plants
Assessment statements
| DCS Topic Code | Statement | Guidance |
| 9.3.U1 | Undifferentiated cells in the meristems of plants allow indeterminate growth. | |
| 9.3.U2 | Mitosis and cell division in the shoot apex provide cells needed for extension of the stem and development of leaves. | |
| 9.3.U3 | Plant hormones control growth in the shoot apex. | Auxin is the only named hormone that is expected. |
| 9.3.U4 | Plant shoots respond to the environment by tropisms. | |
| 9.3.U5 | Auxin efflux pumps can set up concentration gradients of auxin in plant tissue. | |
| 9.3.U6 | Auxin influences cell growth rates by changing the pattern of gene expression. | |
| 9.3.A1 | Micropropagation of plants using tissue from the shoot apex, nutrient agar gels and growth hormones. | |
| 9.3.A2 | Use of micropropagation for rapid bulking up of new varieties, production of virus-free strains of existing varieties and propagation of orchids and other rare species. |
