1. Reflex arc is formed by

muscle → brain → receptor

muscle → spinal cord → receptor

receptor → brain → muscles

receptor → spinal cord → muscle

Adrenal

Liver

Thyroid

Pituitary

4. The image shows the structure of a neuron.

After our nose senses a smell, which option shows the mechanism of the travelling of sense in our body?

Olfactory receptors → dendritic tip of a nerve cell → axon → nerve ending → release of signal → dendritic tip of other nerve cell

Olfactory receptors → dendritic tip of a nerve cell → axon → cell body → release of signal → dendritic tip of other nerve cell

Gustatory receptors → dendritic tip of a nerve cell → cell body → axon → release of signal → dendritic tip of other nerve cell

Gustatory receptors → dendritic tip of a nerve cell → axon → cell body → release of signal → dendritic tip of other nerve cell

5. The main effect of cytokinin in plants is to

improve the quality of fruits

prevent the growth of lateral buds

regulate opening and closing of stomata

stimulate cell division

6. The spinal cord is protected by

aorta

vertebral column

pleura

diaphragm

7. Which of the following acts as both endocrine and exocrine glands?

Adrenal

Pituitary

Ovaries

Pancreas

8. During pollination, plants ensure that the pollen grain from a species germinates on the stigma of the same species. Which of the following ensures this?

Hydrotropism

Chemotropism

Phototropism

Geotropism

9. Abscisic acid controls

cell elongation and cell wall formation

shoot elongation

cell division

leaf fall and dormancy

10. Auxin is a plant hormone that promotes cell elongation and is produced by the apical meristem. It inhibits the growth of lateral buds which are present at nodes (where leaves attach to the stem). As long as sufficient auxin is produced by the apical meristem, the lateral buds remain dormant. A gardener wants the plants in the hedge that he is growing to become bushier with more branches.Which of the following should he do?

Spray water on the tips of the stems to increase growth

Dig around the plant roots and apply more manure

Trim the hedge by cutting off the tips of the stems

Remove all the weeds that grow around the hedge

11. Akash potted some germinated seeds in a pot. He put the pot in a cardboard box that was open from one side. He keeps the box in a way that the open side of box faces sunlight near his window. After 2-3 days he observes the shoot bends towards light as shown in image.

Which type of tropism he observes?

Geotropism

Phototropism

Chemotropism

Hydrotropism

12. Which statement is incorrect about auxins?

They promote the growth of root

They promote the growth of shoot

They influence the formation of flower and ripening of fruit

They inhibit the growth of root

13. Which of the following statements is correct about receptors?

Gustatory receptors detect taste while olfactory receptors detect smell

Both gustatory and olfactory receptors detect smell

Auditory receptors detect smell and olfactory receptors detect taste

Olfactory receptors detect taste and gustatory receptors smell

14. Which part of a nerve cell contains a nucleus?

Axon

Dendrite

Cyton

Nerve Endings

15. Involuntary actions in the body are controlled by

medulla in forebrain

medulla in midbrain

medulla in hindbrain

medulla in spinal cord

16. Which of the following is not associated with growth of plant?

Auxin

Gibberellins

Cytokinins

Abscisic acid

17. Which hormone regulates the ionic balance in the body?

Glucagon

Thyroxine

Testosterone

Vasopressin

18. In plants the role of cytokinin is:

Promote cell division.

Wilting of leaves.

Promote the opening of stomatal pore.

Help in the growth of stem.

19. Which one of the endocrine gland is known as ‘master gland’?

Pancreas

Adrenal

Pituitary

Hypothalamus

20. Which of the following statements are true about the brain?

(i) The main thinking part of the brain is hind brain.

(ii) Centres of hearing, smell, memory, sight, etc. are located in fore-brain.

(iii) Involuntary actions like salivation, vomiting, blood pressure are controlled by the medulla in the hind-brain.

(iv) Cerebellum does not control posture and balance of the body.

(i) and (ii)

(i), (ii) and (iii)

(ii) and (iii)

(iii) and (iv)

21. The hormone that is used to keep flowers fresh is

cytokinin

gibberellins

auxin

abscisic acid

22. Ageing in human beings is caused by disappearance of which of the following glands?

Adrenal

Pituitary

Thyroid

Thymus
