Ultrastructural studies have led to the characterization of two distinctive cytological

pathways of PCD in plants;

I) Vacuolar-type PCD

II) Hypersensitive response-type (HR-type) PCD

a) cytosol and all its organelles, including the plasma membrane, are completely brokendown

b) The vacuole loses water, resulting in marked cell shrinkage, contraction from the cell wall,

and nuclear DNA degradation

c) PCD occurs in leaves in response to microbial attack

d) cell wall is either partially or completely digested as well, as in endosperm tissue

e) Continued water loss from the cytosol leads to the breakdown of the plasma membrane

and the release of residual cellular contents into the apoplast

Given characterization of PCD pathway match with its type PCD?

The autophagy pathway included____

a) the catabolic mechanism that delivers cellular components to lysosomes, where they are degraded

b) Autophagy protects the cell from the harmful or lethal effects of damaged or unnecessary proteins and organelles

c) During starvation, the autophagic breakdown and recycling of cellular components also

ensure cellular survival by maintaining cellular energy levels
