Matthias Schleiden and Theodor Schwann proposed the cell theory. Rudolf Virchow later modified it by stating that all cells arise from pre-existing cells.
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.
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.
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).
