Cell Biology Quiz-22
Dear Readers,
NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions.
About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus.
Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced.

Q3. Flocculation or coagulation of protoplasm is the
Solution
(a) Protoplasm is generally found in two states, peripheral gel like ectoplasm and central sol like endoplasm. Protoplasm shows transformation between sol and gel states is made possible through flocculation or coagulation of protoplasm.

Q4. Most of the bacterial cell envelope consists of
Solution
Most prokaryotic cells, particularly the bacterial cells, have a chemically complex cell envelope. The cell envelope consists of a tightly bound three layered structure, i.e., the outermost glycocalyx followed by the cell wall and the plasma membrane

Q5. The nucleolus is the site of formation of
Solution
Nucleolus forms ribosomal subunits by wrapping the RNA with ribosomal proteins. The ribosomal subunits later leave nucleus through the nuclear pores.

Q6. Which of the following is correct for middle lamella of eukaryotic cell?
Solution
All the given statements are correct
All the given statements are correct
Q7. Which one of the following statements is incorrect about the properties of DNA?
Solution
DNA does not directly participate in protein synthesis
DNA does not directly participate in protein synthesis
Q8. The infoldings in mitochondria are known as
Solution
Structurally, the mitochondria is bounded by two membranes, i.e., the outer and the inner membrane, separated by a space called outer chamber or inter membrane space. The inner membrane is thrown up into a series of folds called cristae.
