Bundle sheath cells

Options

(a) Are rich in RuBisCO
(b) Are rich in PEP carboxylase
(c) lack RuBisCO
(d) Lack both RuBisCO and PEP carboxylase

Correct Answer:

Are rich in RuBisCO

Explanation:

In C₄ plants, bundle sheath cells are rich in RuBisCO, but lack PEP case. The CO₂ released in the bundle sheath cells enters the C₃ or the Calvin pathway, common to all plants. Thus, the basic pathway that results in the formation of sugars, the calvin pathway is common to the C₃ and C₄ plants.
