Plant hormones (biology only) key terms

gibberellins

In Use of plant hormones (HT only), gibberellins means plant hormones that promote growth and are used to end seed dormancy. This matters in Plant hormones (biology only) because it supports the learning objective to describe (HT only) the use of gibberellins to end seed dormancy. Use gibberellins only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

seed dormancy

A period during which seeds are inactive and do not germinate, often requiring specific conditions to break.

gibberellins

Plant hormones that promote growth and are particularly important in stimulating flowering.

flowering

The process by which plants produce flowers, often stimulated by the presence of gibberellins.

gibberellins

In Use of plant hormones (HT only), gibberellins means plant hormones that promote growth and are used to increase fruit size. This matters in Plant hormones (biology only) because it supports the learning objective to describe (HT only) the use of gibberellins to increase fruit size. Use gibberellins only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

fruit size

The measurement of the dimensions of fruit, which can be enhanced by the application of gibberellins.

plant hormones

In Use of plant hormones (HT only), plant hormones means chemicals that coordinate and control plant growth and responses. This matters in Plant hormones (biology only) because it supports the learning objective to evaluate (HT only) agricultural and horticultural uses of plant hormones, including benefits, risks and effects on biodiversity. Use plant hormones only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

biodiversity

The variety of life in the world or in a particular habitat or ecosystem, which can be affected by the use of plant hormones in agriculture and horticulture.
