Explanation / Answer

29-The ribosome is made up of protein and rRNA. Proteins are made in the cytoplasm and rRNA are made in the nucleus. Protein and rRNA are assembled in the nucleolus which is present inside the nucleus.

So correct answer is the option A- nucleolus

30-

The nucleolus is the site for synthesis of the ribosome

Rough endoplasmic reticulum is the site of protein synthesis

the chloroplast is the site for the synthesis of food.

A plant has very large central vacuole which maintains the osmotic pressure and hold bitter and waste compound.

So the answer is an option C- central vacuole

31 -

Rough endoplasmic reticulum is the site of protein synthesis which is destined for other organelles or plasma membrane protein.

Smooth endoplasmic reticulum is the site for lipid synthesis.

The ribosome helps in the synthesis of cytoplasmic proteins.

The lysosome is the organelle which detoxifies poisons and toxin like alcohol

So the answer is the option D lysosomes

32- Rough endoplasmic reticulum is the site of protein synthesis which is destined for other organelles or plasma membrane protein.

Smooth endoplasmic reticulum is the site for lipid synthesis.

The ribosome helps in the synthesis of cytoplasmic proteins.

Proteins which are synthesized by   Rough endoplasmic reticulum is transported to a golgi apparatus where protein undergoes post-translational modification and packaged.

So the answer is the option A- Golgi apparatus

33 -

the chloroplast is the site for the synthesis of food.

The ribosome helps in the synthesis of cytoplasmic proteins.

Mitochondria are the organelle which helps in generation of ATP.

The lysosome is the organelle which helps in breaking down polymer into monomer as it has an enzyme which cleaves polymer into a monomer.

So the answer is option B- lysosomes.

34 -

Nucleus helps is the storehouse of genetic material

Cytoskeleton help in maintaining the structure of the cell.

A plant has very large central vacuole which maintains the osmotic pressure and holds bitter and waste compound.

Material which is synthesized in the rough and smooth endoplasmic reticulum are transferred to Golgi apparatus where they are further processed as per their destination

So the answer is option D- Golgi apparatus.

35- Flagella is a structure which helps cells in their motility. Flagella is made up of the cytoskeleton

SO answer is the option A- flagella.
