(a) Ribosomes are made of 50S and 30S subunits
(b) They can have plasmids
(c) They contain mesosomes
(d) They have peroxisomes

Choose the correct answer from the options given below:

Prokaryotes possess 70S ribosomes (50S + 30S), plasmids and mesosomes, but they lack membrane-bound organelles such as peroxisomes.

Question 84 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Neural Control And Coordination

Which of the following is not a part of the human central nervous system?

Arachnoid, dura mater and pia mater are the three meninges covering the brain and spinal cord. Pericardium is the protective covering of the heart.

Question 85 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Cell The Unit Of Life

Mitochondrial inner membrane encloses _________.

The inner mitochondrial membrane encloses the mitochondrial matrix, which contains enzymes of the Krebs cycle, mitochondrial DNA and ribosomes.

Question 86 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Cell The Unit Of Life

Match List-I with List-II:

List-I	List-II
A. Cristae	I. Flat membrane sacs in stroma of chloroplast
B. Cisternae	II. Infoldings in mitochondria
C. Thylakoids	III. Cell membrane
D. Phospholipid	IV. Disc-shaped sacs in the Golgi apparatus

Cristae are infoldings of the inner mitochondrial membrane. Cisternae are flattened sacs of the Golgi apparatus. Thylakoids are membrane sacs in chloroplasts. Phospholipids are major components of cell membranes.

Question 87 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Cell The Unit Of Life

The plastid that stores xanthophyll is known as

Chromoplasts contain carotenoid pigments such as carotene and xanthophyll, giving yellow, orange and red colours to plant parts.

Question 88 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Chemical Coordination And Integration

Which of the following statements related to the pituitary gland are correct?

(a) It is divided anatomically into adenohypophysis and neurohypophysis.
(b) It secretes follicle stimulating hormone.
(c) It secretes melanocyte stimulating hormone.
(d) It does not secrete prolactin.

Choose the correct answer from the options given below:

The pituitary gland consists of adenohypophysis and neurohypophysis. It secretes FSH, MSH and prolactin. Therefore statement (d) is incorrect.

Question 89 of 90

🟢 Re NEET 2026 📘 CLASS XI 🌿 Photosynthesis In Higher Plants

Photorespiration reaction catalyzed by RuBisCo is shown below:

RuBP + O₂ → 3-Phosphoglycerate + X

Identify "X" from the given options:

During photorespiration, RuBisCo oxygenates RuBP to produce one molecule of 3-phosphoglycerate and one molecule of 2-phosphoglycolate.

Question 90 of 90

🟢 Re NEET 2026 📘 CLASS XII 🌿 Organisms And Populations

Given below are two statements:

Assertion (A): The logistic growth model of populations is considered more realistic than the exponential growth model.

Reason (R): Resources are finite.

In the light of the above statements, choose the most appropriate answer from the options given below:

The logistic growth model is more realistic because environmental resources are limited. As resources become limiting, population growth slows and approaches the carrying capacity (K).
