Answer:
b chemical potential energy
Answer:
The correct answer is A it transport the food generated by photosynthesis.
Explanation:
Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.
Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.
Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.
Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
One triglyceride molecule produces three fatty acid molecules with up to 16 or more carbon atoms each, so fat molecules provide more energy than carbohydrates and are an important source of energy for the human body.
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds. Depending on the context, the term may or may not include ions that meet this criterion.
In quantum physics, organic chemistry, and biochemistry, the distinction between ions has been abolished and the molecule is often used when dealing with polyatomic ions.
The molecule can be homonuclear. H. is made up of atoms of chemical elements. Two atoms of an oxygen molecule. Or it can be heteronuclear, which is a compound made up of multiple elements.

I hope this counts - cell wall! helps keep most materials out but allows specific materials to pass through. animal cells do not have a cell wall
