What type of cells makes leaves somewhat flexible
|
collenchyma, which are unevenly think
|
|
parenchyma, which are high in mitochondria needed to change shape
|
|
Sclerenchyma (scleroid cells) which are gritty
|
|
Sclerenchyma, which have think cell walls high in lignin
|
Explanation:
Detailed explanation-1: -Collenchyma cells provide structure and support to the plant but still allow for flexibility, unlike other supporting ground tissue cell types, like sclerenchyma cells which are more rigid.
Detailed explanation-2: -Collenchyma tissues are composed of oval or prismatic cells that are commonly elongated and can occur in long strands or cylinders. Collenchyma tissue is specialised to provide flexibility to various parts of the plant like petiole and stem since they are non lignified. It allows for easy bending without breakage.
