Question

Find out the false sentences

• A. Golgi apparatus is involved with the formation of lysosomes
• B. Nucleus, mitochondria and plastid have DNA; hence they are able to make their own structural proteins
• C. Mitochondria is said to be the powerhouse of the cell as ATP is generated in them.
• D. Cytoplasm is called as protoplasm

Answer 1

The correct option is D

Cytoplasm is called as protoplasm

The correct option is D.

The explanation for the correct option:

1. Protoplasm is the living part of a cell including the cytoplasm, nucleus, and organelles.
2. The cytoplasm is all the materials inside the cell membrane except the nucleus.
3. The cytoplasm is mostly formed of water, salts, and proteins

Explanations for the incorrect option:

Option A

1. Golgi bodies are densely shaded reticular structures around the nucleus.
2. The Golgi cisternae are arranged around the nucleus with separate convex cis or the forming face and concave trans or the maturing face
3. The Golgi apparatus has the function of packaging materials and releasing them into or out of the cell
4. Materials that need to pack in the form of vesicles from the endoplasmic reticulum fuse with the cis face of the Golgi apparatus and progress towards the trans face.
5. Lysosomes have a membrane and it is a vesicular structure formed by the process of packaging in the Golgi apparatus
6. The enzymes are released from the Golgi apparatus in small vesicles that fuse with the acidic vesicles of the Golgi apparatus and form a lysosome.

Option B

1. Each mitochondrion is a double membrane-bound organelle with an outer membrane and the inner membrane.
2. Its lumen is called a matrix.
3. The matrix also consists of a single circular DNA molecule, a small number of RNA molecules, ribosomes (the 70S), and the elements required for the synthesis of proteins.
4. Plastids bear some specific pigments, thus imparting specific colors to the plants
5. The lumen of chloroplast called stroma
6. Chloroplast also contains small, double-stranded circular DNA molecules and ribosomes(the 70S).
7. The nucleus is also a double membrane organelle.
8. The nucleoplasm contains nucleolus and chromatin.
9. Chromatin contains DNA.
10. In all three organelles the DNA form protein by the process of transcription and translation.
    

Option C

1. Mitochondria are the sites of aerobic respiration.
2. ETS undergone in mitochondria produces energy in form of ATP.
3. They produce energy inside the cell in the form of ATP, so they are called the powerhouse of the cell.

Final answer: The cytoplasm is the part of protoplasm is the incorrect statement.
