Important NEET Questions with Solutions on Cell the Unit of Life

The Cell: The Unit of Life is an important chapter in the NEET 2025 Syllabus from the Class XI curriculum. Here we have discussed the list of important questions with solutions on the Cell the Unit of Life.

Q.1 Which statement on cilia is incorrect?

1. Microtubules of cilia are composed of tubulin
2. The organized beating of cilia is controlled by fluxes of Ca2+ across the membrane
3. Cilia are hair-like cellular appendages
4. Cilia contains an outer ring of nine doublet microtubules surrounding two singlet microtubules

Answer: B

Explanation: The organized beating of cilia is controlled by the regulated sliding of the external duplicate microtubules

Q.2 This ribosome is engaged in protein synthesis in animal cell

1. Ribosomes of only cytosol
2. Ribosomes which occur on the nuclear membrane and ER
3. Ribosomes of only mitochondria and cytosol
4. Ribosomes of only nucleolus and cytosol

Answer: B

Explanation: Ribosomes found on the nuclear membrane and endoplasmic reticulum (ER) are involved in protein synthesis in animal cells

Q.3 Cellular totipotency is demonstrated by

1. Only bacterial cells
2. Alll eukaryotic cells
3. All plant cells
4. Only gymnosperm cells

Answer: C

Explanation: Cellular totipotency is the ability of a cell to divide into another type of cell in an organism

Q.4 The telomeres of eukaryotic chromosomes consist of short sequences of

1. Guanine rich repeats
2. Thymine rich repeats
3. Cytosine rich repeats
4. Adenine rich repeats

Answer: A

Explanation: In vertebrates, the sequence of nucleotides in telomeres is TTAGGG. In humans, telomeres can contain thousands of repeats of this sequence.

Q.5 Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on

1. Proton gradient
2. Accumulation of Na ions
3. Accumulation of K ions
4. Membrane potential

Answer: A

Explanation: As per the theory of ATP, a proton-motive force is created by a proton gradient.

Q.6 This structure between two adjacent cells is an effective transport pathway

1. Plasmalemma
2. Plastoquinones
3. Plasmodesmata
4. Endoplasmic reticulum

Answer: C

Explanation: Plasmodesmata are several tiny channels that connect the cytoplasm of the adjacent plant cells. This connection allows free movement of different molecules like sugars, amino acids, and water between them

Q,7 Pick the correct statement from these regarding the cell membrane

1. Lipids are arranged in a bilayer with polar heads towards the inner part
2. Na+ and K+ ions move across cell membranes by passive transport
3. Fluid mosaic model of the cell membrane was proposed by Singer and Nicolson
4. Proteins make up 60-70% of cell membrane

Answer: C

Explanation: As explained by scientists Singer and Nicolson, the fluid mosaic model is the most popularly accepted form for the cell membrane structure. It describes the fluid as a bilayer of lipids with embedded proteins, proposed by scientists

Q.8 This cell organelle is responsible for extracting energy from carbohydrates to form ATP

1. Lysosome
2. Ribosome
3. Chloroplast
4. Mitochondrion

Answer: D

Explanation: Mitochondria are referred to as the "powerhouse of the cell." This is because most cellular energy (ATP) is produced through cellular respiration, during which carbohydrates are broken down to release energy.

Q.9 Animal cells are connected by

1. Desmosome
2. Cell wall
3. Cell Membrane
4. Plasmodesmata

Answer: D

Explanation: Plasmodesmata are thin cytoplasm that connect the cytoplasm of neighboring cells. It allows the exchange of protein and ions. Animal cells are connected by plasmodesmata.

Q.10 The Hammerling Experiment on Acetabularia involves the exchanging of

1. Nucleus
2. Cytoplasm
3. Gametes
4. Rhizoid

Answer: A

Explanation: Acetabularia is a model designed by Joachim Hämmerling for studying cell biology. The experiment explains a giant unicellular organism that is typically found in subtropical waters.
