The steps involved in the mechanism of vision are given below. Arrange them in proper sequence and select the correct option. A. Dissociation of retinal from opsin and generation of potential difference in photoreceptor cells. B. Focusing of the light rays in visible wavelength on the corner through the lens. C. Generation of the action potential in ganglion cells through bipolar cells. D. Analysis of neural impulse and formation of aa image on the retina. E. Transmission of the action potential by the optic nerve to the visual cortex.

Which of the following statements is/are true A. The apoplastic movement of water occurs exclusively through the cell wall without crossing any membranes B. Solutes present in a cell ( or in any solution ) increase the free energy of water or water potential C. The symplastic movement occurs from cell to cell through the plasmodesmata D. Membrane permeability depends on the membrane composition, as well as the chemical nature of the solute

A list of steps involved in mechanism of vision is given below in a random order. (i)Neural impulses are analysed and image formed on retina is recognised by visual cortex. (ii)Membrane permeability changes (iii)Ganglion cells are excited (iv)Bipolar cells are depolarised (v)Action potentials (impulse) are transmitted by optic nerves to visual cortex. (vi)Potential differences are generated in the photoreceptor cells. (vii)Light energy causes a change in shape of rhodopsin, leading to the dissociation of retina (an aldehyde of vitamin A ) from opsin (a protein) (viii)Structure of opsin is changed. Which of the following options represents these events in a correct order ?

Which of the following is incorrect about the epithelium found in the lining of intestine (A) helps in secretion and absorption (B) composed of tall and slender cells (C) cells bear cilia on their free surface (D) cells have nuclei at their base

Match the following and choose the corrct option. A. Leaves (i)Anti-transpirant B. Seed (i) transpirant C. Roots (iii) Negative osmotic potential D Aspirin (iv) Imbibition E Plasmolysed cell (v) Absorption

Make corrections wherever you find mistake in spellings/words in the following paragraph/sentences. (A) Protozoans are generally multinucleate, but all ciliates and many amoeboid types are uninucleate. (B) Contractile vacuoles are found in almost all terrestrial protozoans for maitenance of carbon concentration of cell body, the phenomenon is known as osmoregulation. Contractile vacuole also helps in reproduction. (C) The protozoan cell body is either naked or surrounded by a rigid pellicle. Cellulose is present in pellicle. Some protozoans secrete shells of various organic compounds as external covers. (D) Ascomycetes are coenocytic as well as multicellular fungi. In the later, mycelium is asceptate. The asexual spores are formed in chains are called zoospores. The spores are formed endogenously, i.e., inside sporangium. (E) Sexual reproduction in Rhizopus is oogamous and the mode of sexual fusion is gametangial contact type. (F) A lichen is structurally organised entity consisting of the permanent association of a fungus and an alga. The fungal component of a lichen is called phycobiont and the algal component is called mycobiont. Both mycobiont and phycobiont are associated in parasitic union in which the fungus is more predominant and alga is subordinate partner.

Study the following characters. A.Secretion B.Absorption C.Protection D.Movement of particles in a specificn direction E.Nuclei at the base of cells . Which of the above functions are related to simple cuboidal epithelium?
