What is Heteroblasty !? :thinking:

Heteroblasty is *significant and abrupt change in form and function that occurs over the lifespan of certain plants. Characteristics affected include internode length and stem structure as well as leaf form, size and arrangement.

Cardamine have Knox gene, so that’s why we can able to see 2 type of leaves - Simple leaves & compound leaves.

KNOX1 genes coordinately control the leaf development and different combinations of those genes which produce diverse leaf shapes including broad, lobed and compound leaves.
