Here are the answers to your questions based on common knowledge about plant tissue staining and microscopy:
Question 1:
What is the primary purpose of Safranin staining?
Answer: Differentiate and highlight specific components and structures of the specimen
Question 2:
What is the purpose of adding Glycerine after the Safranin stain?
Answer: All of the above (Prevent evaporation, Create optical clarity, Preserve the specimen)
Question 3:
What type(s) of tissue are seen during this lab? (Select all that apply)
Answer: Parenchyma, Xylem, Sclerenchyma, Phloem
Question 4:
Parenchyma cells are the most common and versatile cells. They are thin and contain large vacuoles. Where are they typically located?
Answer: All of the above (Leaves, Stems, Roots)
Question 5:
Sclerenchyma cells were observed in the stem of the plant. What is the primary function of these cells?
Answer: Support and protection of the plant
Question 6:
Why does sclerenchyma have a narrow lumen?
Answer: The cells have thick lignified cell walls leaving the lumen narrow
Question 7:
