Acid-fast and Gram is used to visualize the structures in a membrane.
It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>
Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.
They stain poorly with Gram stain procedure, and appears as weak Gram-positive.
Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and
<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>
To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.

Answer:
d. Actively transported into the phloem
Explanation: Source is the place where sugar are been produced and are active transported to actively growing part of plants that requires it. The actively growing plants part that requires sugar are called sink.
Photosynthate the end products of photosynthesis is what is been loaded into the phloem through active transport and then moved to sink i.e plant part that requires the sugar through a process called translocation. The sink in plant includes the fruits, leaves for some vegetables,flowers for ornamental crop,too or tuber, rhizomes.
When the phloem cell is damage there is reduction in transport of photosynthate or accumulation in a particular part of plant.
Actively growing parts of plant have a high demand for sugar or sucrose than the old and weak parts of plants.
The answer is Minerals hope this help
