RHS Level 2 Certificate Year 1 Week 5 More growth and life cycles

Learning outcomes Growth 1.1 State the basic changes that occur when woody dicotyledons undergo secondary growth/thickening. 1.2 State how strengthening tissue can be established in monocotyledons allowing perennial growth to occur. 1.3 State the internal differences between monocotyledons and dicotyledons. 2. Plant life cycles 2.1 Define the terms: ‘annual’, ‘ephemeral’, ‘biennial’ and ‘perennial’. 2.2 Define the terms: ‘tender’, ‘half-hardy’, and ‘hardy’ in relation to annuals. 2.3 Define the terms: ‘tender’, ‘half-hardy’, ‘hardy’, ‘herbaceous’ and ‘woody’ in relation to perennials. 2.4 State the meaning of the terms: ‘ evergreen’, ‘semi-evergreen’ and ‘deciduous’. 2.5 Describe what is meant by the terms: ‘juvenility’, ‘maturity’ and ‘senescence’ in the development cycle of a plant and state their horticultural significance. 3.

Growth We have seen how growth takes place at the meristems – extending the roots and shoots. Secondary growth – dicotyledons. Producing thickened stems, creating ‘wood’. Strengthening growth – monocotyledons Internal differences – monocotyledons and dicotyledons
