46
Q

Bundle sheath cells

A

Cells arranged into tightly packed sheath ls around the veins of a leaf

47
Q

PEP carboxylase features

A

Higher affinity for CO2 than rubisco and no affinity for O2

48
Q

PEP carboxylase

A

Enzyme that adds CO2 to PEP to make oxalacetate in mesophyll cells of C4 plants

49
Q

Crassulacean acid metabolism

A

Plants fix CO2 into variety of organic acid at night and release organic molecules at day
