MIUN Free NEET Quiz Unit 2

1. We do not need to know about the possible variations in different parts, found as adaptations of the plants to their environment, e.g., adaptations to various habitats, for protection, climbing, storage, etc.

2. In roots, the metaxylem lies towards epidermis and protoxylem lies towards the centre.

3. A tissue is a group of cells, including intercellular substances, performing one or more bodily functions.

4. Anatomically, a plant is made of similar kinds of tissues.

5. In china rose, all stamens are united into more than two bunches/bundles.

6. Root system is either tap root or fibrous.

7. Brinjal — food — Solanaceae.

8. Similar to other plant parts, leaves can undergo modifications to form structures such as tendrils or spines, serving purposes like climbing or protection.

9. Even though the angiosperms show such a large diversity in external structure or morphology, they are all characterised by presence of roots, stems, leaves, flowers and fruits.

10. In cockroach, a short extension of the prothorax that connects head is known as oesophagus.

11. Sclerites are dorsal, whereas sternites are ventral in the cockroach exoskeleton.

12. Toward the pith lies the protoxylem in stems, and the metaxylem extends away from the pith.

13. Circulatory system is closed with single circulation in frogs.

14. Tergites are dorsal, whereas sternites are ventral cockroach exoskeleton.

15. Adhering junctions help to stop substances from leaking across a tissue.

16. The stem is the descending part of the axis bearing branches, leaves, flowers, and fruits.

17. In multicellular organisms, not all functions like digestion, respiration, and reproduction are performed by a single cell.

18. A glabrous stem in botany refers to a stem that is smooth and lacks any hairs, trichomes, or other surface structures.

19. Some plants undergo root modifications for food storage, mechanical support, and respiration.

20. In stems, the protoxylem lies away the pith and the metaxylem lies towards from the centre.

21. Seeds do not vary in shape, size, or period of viability.

22. When two or more organs perform a common function by their physical interaction, they together form organ system, e.g., digestive system, respiratory system, etc.

23. Frog cannot respire in water through skin.

24. In mustard, not all the stamens are at same height.

25. The thorax of the cockroach has all the joined appendages.

26. In china rose, all stamens are united into one bunch/bundle.

27. The conjoint vascular bundles usually have the phloem located only on the both side of xylem.

28. In the male cockroach, the 10th segment bears a pair of jointed filamentous structures called anal cerci.

29. The vascular bundles form the conducting tissue and do not translocate water, minerals, and food material.

30. The wide range in the structure of higher plants will fail to fascinate us.

31. The epidermal tissue systems are made of epidermal cells, stomata, and the epidermal appendages.

32. Seeds are uniformly monocotyledonous and lack any variation in cotyledon number.

33. Sub-stomatal cavity is more conspicuous in dicot leaf.

34. Stems do not undergo any modifications and serve no specific functions.

35. In cockroach, a short extension of the prothorax that connects head is known as neck.

36. The roots in some plants get modified for storage of food, mechanical support, and respiration.

37. Morphological features such as nodes and internodes are absent in stems, making it difficult to differentiate them from roots.

38. Leaves emerge laterally from stems at nodes, serving as the primary sites for photosynthesis.

39. In china rose, all stamens are united into two bunches/bundles.

40. In stems, the protoxylem lies towards the centre and the metaxylem lies away from the centre.

41. Only a few higher animals consist of only four basic types of tissues.

42. In opposite type, a single leaf arises at each node and lie opposite to each other.

43. Sun flower is an example of alternate venation.

44. In plants the fundamental tissue system is also known as conducting tissue system.

45. Tomato — food — Liliaceae.

46. Flowers of Solanaceae members are bisexual, actinomorphic.

47. Epithelia have two free surfaces facing a body fluid and the outside environment.

48. The calyx of Solanaceae members maybe sepals five, united, persistent, imbricate aestivation.

49. Some stems perform the function of storage of food.

50. The parallel venation in monocot leaves is reflected in the exactly similar sizes of vascular bundles (except in main veins) as seen in longitudinal sections of the leaves.
