Physiological process

Attached organ

Detached organ

Absorption/ Uptake

Roots absorb water and minerals

from the soil and translocation

takes place

Does not have root to absorb

water and minerals so no

translocation

Photosynthesis

Photosynthesis takes place and

translocation of food materials to

other organs

Generally, no photosynthesis

though take place no translocation

to other organs

Transpiration

Transpiration loss is supported by

absorption means of temperature

mgmt

No any supported means and

cause weight loss and shriveling

Respiration

Break down of substrate and release of energy; loss of substrate

is supported by photosynthesis

Breakdown of substrate and

release of energy; loss of substrate

is not supported by photosynthesis

Ripening and senescence

Co-factors or ripening inhibitors

are regularly supplied by the

plants so delay ripening and

senescence

No co-factors or ripening

inhibitors are regularly supplied so

fast ripening and senescence
