The thin external covering is similar to the the organelle with a texture like sandpaper is the
1.a)cell membrane
b)cytoplasm
c)ribosome
2.a)golgi body
b)lysosome
c)rough endoplasmic reticulim

The correct answer is 1. A) cell membrane and 2. C) rough endoplasmic reticiculum.

Explanation:

The outer covering of any cell is called cell membrane. Cell membrane is the outermost layer of the cell that enclose all cell organelle and cytoplasm. It is made of lipid bilayer.

The organelle with a texture like a sand paper is the rough endoplasmic reticulum. Rough endoplasmic reticulum is present in eukaryotic cells. Its major role is to generate proteins.

Thus, the correct answer is 1. A) cell membrane and 2. C) rough endoplasmic reticiculum.
