4.5.4.1 Control and coordination
| Content | Key opportunities for skills development |
|---|---|
Plants produce hormones to coordinate and control growth and responses to light (phototropism) and gravity (gravitropism or geotropism). Unequal distributions of auxin cause unequal growth rates in plant roots and shoots. |
Required practical activity 8: investigate the effect of light or gravity on the growth of newly germinated seedlings.
Record results as both length measurements and as careful, labelled biological drawings to show the effects.
AT skills covered by this practical activity: AT 1, 3, 4 and 7.
This practical activity also provides opportunities to develop WS and MS. Details of all skills are given in Key opportunities for skills development.
