Give three reasons why plants can get along without respiratory organs.

Choose incorrect option for given below organism

Read the following statements and find out the incorrect statements. a. Ultimately all the food that is respired for life processes comes from photosynthesis. b. The energy released by oxidation in respiration is directly used for the life processes. c. The carbon skeleton produced during respiration is used as precursors for biosynthesis of other molecules in cell. d. Plants, unlike animals, have no specialised organs for gaseous exchange but they have stomata and lenticels for this purpose. e. During oxidation within a cell, all the energy contained in respiratory substrates is released free into the cell in a single step, which is trapped as chemical energy in the form of ATP.

What are the reasons why plants can get along without respiratory organs? a. Each plant part takes care of its own gas exchange needs. There is very little transport of gases from one plant part to another. b. Plants do not present great demands for gaseous exchange, root, stem and leaves respire at rates far lower than animals do. c. The distance that gases must diffuse even in large, bulky plants is not great.

Assertion (A): In plants there are no specialised respiratory organs. Reason (R): Plants do not require great demands of gaseous exchange.

Assertion :- Plants are devoid of specialised respiratory organs. Reason:- Each plant part takes care of it's own gaseous exchange needs .
