Question

A potted geranium sits in a windowsill absorbing sunlight. How does a root cell (which is not exposed to light) obtain energy to do cellular work such as active transport across its membrane?
options:

ATP is made in the leaves via photosynthesis and moved to the root.


Sugar is made in the leaves via photosynthesis and moved to the root.


The root cell makes ATP by cellular respiration using material absorbed from the soil.


The root cell makes sugar using the dark reactions (Calvin cycle) of photosynthesis.

Answer 1

Explanation:

Sugar is made in the leaves via photosynthesis and moved to the root.

Sugars made in the leaves via photosynthesis are stored elsewhere and transported to the root system. They are then available for respiration and oxidative phosphorylation which do not require light energy. The

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen (from the light reaction) is released.

 

Further Explanation:

Respiration in the mitochondria utilizes glucose along with oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycolysis). Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain and the energy they release is used in pumping H+ to produce ATP from ATP synthase. At the end of the ETC molecules of oxygen accept electrons and protons to form molecules of water.
