Question

Which of the following statements are not true for eukaryotic cells?
(i) They do not have a nuclear membrane.
(ii) They have a well-organised nucleus.
(iii) They have a nuclear membrane.
(iv) Blue-green algae are eukaryotic cells

Answer 1

Answer:

(I)

Explanation:

eukaryotic cells have nuclear memberane

Answer 2

(i) They do not have a nuclear membrane is the wrong statement.

• The nuclear membrane is available in both the plant and animal cells.
• Cells complete a large number of functions, such as protein building, transformation of particles into energy and eliminates the useless products.  
• This layer watches the hereditary material of the cells against the outside of the nucleus where substance responses are occurring.
• Additionally, it conveys a few proteins which are vital in the association of DNA and to control genes.  
• The nucleus is a twofold bound cell organelle that is situated in the eukaryotic cells and is made of the cell's hereditary material, the DNA.
• Since it keeps up with the uprightness of the quality that control the gene articulation, henceforth controlling the cell's exercises, it is known as the control focus of the cell.  
• The nuclear membrane encases the DNA inside the nucleus and shields it from the substances in the cytoplasm.
• The nuclear membrane gives legitimate shape to the nucleus and guarantees that the cytoplasm doesn't spill into the nucleus.
• On the off chance that the nuclear membrane was missing, the particles in the cytoplasm would go into the nucleus and annihilate a piece of the DNA.
• This would weaken the working of the cell and would prompt cell demise.
