Answer:
In both cases, rubisco is not used to fix carbon initially (Ans C)
Explanation:
Photosynthesis is similar in C4 plants and CAM plants because they separate the light and dark reactions to reduce photorespiration. Plants which lives in dry and hot condition may be C4 plants and CAM plants have an alternative method of carbon fixation.
In C4 plants carbon dioxide is taken into the leaves through the stomata present in leaves but is converted to a 4 carbon molecule, then this molecule can be pumped to the deeper layer present on the leaves for the Calvin cycle to occur away from the presence of the oxygen.
CAM plants take in carbon dioxide at night time and convert them to other carbon molecules which can be stored in the vacuole. During the day time, CAM plants shut their stomata and instead utilize the carbon which was brought at night to reduce water loss and photorespiration.
During photorespiration plants shut their stomata and reduce the intake of CO2 and reduce water loss, with a limited amount of CO2, rubisco uses oxygen instead of CO2 in the dark reaction. (which is present in both C4 and CAM plants)
The cytoplasm :)
the cytoplasm is like the jelly that fills in the cell where everything else sits in. without the cytoplasm, the cell would not have any structure.
Okay ? is this a question or a statement
The presence of hydrogen bond is one factor that explains the fact that ice floats over water because it has less density.
Due to this, rivers and lakes freeze from the surface whereas it is in liquid state at the bottom which allows the sea animals to survive even in colder temperatures.
Water makes up at least 70% of earth and 65% of our bodies and this property of water is essential for our lives as it maintains the survival.
