(02.03 lc)
what is the difference between the rough and smooth endoplasmic reticulum?
a the rough endoplasmic reticulum is found in plant cells, while the smooth endoplasmic reticulum is found in animal cells.
b the rough endoplasmic reticulum is found in animal cells, while the smooth endoplasmic reticulum is found in plant cells.
c the rough endoplasmic reticulum breaks down waste, while the smooth endoplasmic reticulum produces energy.
d the surface of rough endoplasmic reticulum is covered in ribosomes, while the smooth endoplasmic reticulum is not covered in ribosomes.

Explanation:

First Question (What is the gel - like fluid...):

• Option a: Chloroplast is an organelle in plant cells that is responsible for photosynthesis, not a gel - like fluid.
• Option b: Cytoplasm is the gel - like fluid that fills the cell and surrounds the organelles.
• Option c: Mitochondria are organelles that are responsible for producing energy (ATP) in the cell, not a fluid.
• Option d: Ribosomes are small organelles (or structures) that are involved in protein synthesis, not a fluid.

• Option a: Both rough and smooth endoplasmic reticulum can be found in both plant and animal cells. So this option is incorrect.
• Option b: Both rough and smooth endoplasmic reticulum are present in both plant and animal cells. This option is wrong.
• Option c: The rough endoplasmic reticulum is mainly involved in protein synthesis (because of the ribosomes on its surface), and the smooth endoplasmic reticulum is involved in lipid synthesis, detoxification, etc. Mitochondria break down waste and produce energy, not the endoplasmic reticulum. So this option is incorrect.
• Option d: The key difference between rough and smooth endoplasmic reticulum is that the surface of the rough endoplasmic reticulum is covered with ribosomes (which give it a "rough" appearance), while the smooth endoplasmic reticulum does not have ribosomes on its surface.

Answer:

b. Cytoplasm

Second Question (What is the difference between...):
