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.
Answer:
C. serous cells and mucous cells
Explanation:
Salivary glands consist of serious acini and/or mucous acini. The serous acini represent the serous fluid secreting part of the salivary glands and is composed of serous cells. The mucous acini are made of mucous secreting cells.
The parotid salivary glands consist of serous cells only while the sublingual glands and submandibular cells have both serous and mucous cells.
