Answer 1

Answer:

Middle lamella occurs (D)

Answer 2

1. The other two cell wall networks are Pectic and glycoprotein(C ) other than cellulose microfibrils.

2. Middle lamella occurs (D) Outer to primary wall.  

3. Hydrophilic chemical of cell wall is Pectin (A).

4. Structural element of cell wall is  (B) Microfibrils.

5. Different layers of cell wall are (C) Middle lamella, primary wall and secondary wall.

6. The first wall layer of cell is (D) Middle lamella.

7. Plant cells are distinguishable from animal cell in containing ribosomes (B). As the plant cells do not have ribosome as they have composed protein and ribosomal RNA.
