<span>Two types of processes that contribute to the formation of the proton gradient are 1) </span>processes that release H+ from compounds that contain hydrogen, and; 2) processes that transport H+ across the thylakoid membrane.
If you mean the xylem pump, then after the ATP attaches to it the water can travel trough the xylem tube and get to the stomata and through osmosis travels through the semi-permeable membrane allowing it to open and allow to get In for photosynthesis
Answer:
Nucellus makes the most of the ovule. It encloses the embryo sac. They have abundant food reserves and therefore act as nutritive tissues for the embryo in some plants.
Answer:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.

Answer:
The correct answer is B) binds to the complementary sequence of target mRNAs
Explanation:
Double stranded RNA can be used to block the expression of target mRNAs.
At first the introduced double stranded RNA is being separated into single stranded RNAs .One of the Single stranded RNA is degraded.
The remaining Single stranded RNA binds to the target mRNA by complementary base pairing and blocks the expression of that single stranded RNA.
