Answer:
The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs
Explanation:
In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.
Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.
Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.
Answer:
B) Autotrophes
Explanation:
Producers are <u>autotrophes</u> because, they make their own food. Hence, the option (b) is the correct answer.
First we can look at the taxonomic order:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
The largest level would be the one closest to the top of the list because it is the least specific and therefore the most inclusive. Out of the choices given, phylum is closest to the top, so that is the answer.
