Answer: True.
Explanation:
Nitric oxide(N,O) is a signaling molecule produced by NO synthase which is a transmitter in the nervous system. In the central nervous system NO is generated by the activation of glutamate receptor. When it is produced, it diffuses out of the cells and act on neighbouring cells.

<u>Answer:</u>
C is the answer.
<u></u>
<u>Explanation:</u>
Organelles (the smallest in this situation) are what you can find inside a cell (example: nucleus, mitochondria, etc..). 
Cells are what make up tissues (such as muscles). 
Tissues make up organs (such as the heart) and organs make up organ systems (such as the circulatory system).
 
        
             
        
        
        
I originally asked for the images but I will give it my best shot at answering your question without them! :D
There are only three types of plant tissues:
1. Dermal
2. Ground
3. Vascular
The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the  the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue. 
The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.
Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.
