Question

Sub protoplasts do not contain the entire contents of plant cells and those that contain only a few of all chromosomes and a fraction of the cytoplasm are called as:

• A. Cytoplasts
• B. Karyoplasts
• C. Microprotoplasts
• D. Microplasts

Answer 1

Answer:

C. Microprotoplasts

• Micro protoplasts are a specific type of sub protoplast that contains only a small portion of the plant cell's contents. They are characterized by having a few chromosomes and a fraction of the cytoplasm, which distinguishes them from other protoplast fragments.

• Cytoplasts: These are enucleated protoplasts, meaning they contain the cytoplasm and organelles but lack a nucleus.

• Karyoplasts: These are isolated nuclei enclosed in a thin layer of cytoplasm and plasma membrane. They are essentially the "head" of the cell without the bulk of the cytoplasm.
