9. Conjoint vascular bundles are common in roots.

10. Toward the cortex in roots is the protoxylem, whereas the metaxylem lies away from the pith.

11. In an isobilateral leaf, the stomata are present on both the surfaces of the epidermis.

12. Intercellular substances are included in the tissue along with the cells.

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

14. Fruit of Solanaceae members is mostly berry or drupe.

15. The region of the stem where primary roots are born is called node, while internodes are the portions between two nodes.

16. Leaves vary significantly in shape, size, margin, apex, and extent of leaf blade incisions (lamina).

17. Classification and identification of flowering plants are largely based on floral characteristics.

18. The body of a complex organism like Hydra is made of different types of cells, and the number of cells in each type can be in millions.

19. In cockroach, the first pair of wings arises from the mesothorax.

20. In unicellular animals, a group of similar cells along with intercellular substances perform a non-specific function.Such an organisation is called tissue.

21. The protoxylem in stems lies toward the centre, and the metaxylem is set toward the hypodermis.

22. In whorled phyllotaxy, it is described that a pair of leaves arises at every node in an alternate manner.

23. In whorled phyllotaxy, the arising of a single leaf at each node is stated to occur in an alternate manner.

24. Vascular tissue system is a type of plant tissue system.

25. The parallel venation in monocot leaves is reflected in the near similar sizes of vascular bundles (except in main veins) as seen in vertical sections of the leaves.

26. In male cockroach, the 7th tergum is boat shaped.

27. In plants the vascular tissue system is also known as ground tissue system.

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

29. The anatomy of monocot leaf is similar to that of the dorsiventral leaf in many ways.

30. Meristem is divided into three zones – cortex, pericycle and pith.

31. In multicellular animals, a group of similar cells along with intercellular substances perform a specific function.Such an organisation is called tissue.

32. The vascular bundles are surrounded by a layer of thin walled bundle sheath cells in dicot leaves.

33. Sunflower is given as an example of alternate phyllotaxy.

34. In an isobilateral leaf, the mesophyll is differentiated into palisade and spongy parenchyma.

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

36. Adhering junctions perform cementing to keep neighbouring cells together.

37. In unicellular organisms, all functions like digestion, respiration, and reproduction are performed by a single cell.

38. Few cells in the epithelium are held together with little intercellular material.

39. Bulliform cells are present in the adaxial epidermis of a dicot leaf.

40. In dorsiventral leaf, certain adaxial epidermal cells along the veins modify themselves into large, empty, colourless cells, called bulliform cells.

41. Antennae are a pair of sensory structure in cockroach.

42. On the basis of their structure and location, tissue system are five types.

43. Many plants belonging to Solanaceae family are source of food (tomato, brinjal, potato), spice (chilli); medicine (belladonna, ashwagandha); fumigatory (tobacco); ornamentals (petunia).

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

45. Frog can respire in water through skin and through lungs on land.

46. Knowing/studying the adaptions of the plants to various habitats, is useful to classify them.

47. There are numerous large spaces and air cavities between spongy palisade cells.

48. At each node, three or more leaves are said to arise in an alternate manner in the opposite type of phyllotaxy.

49. The place where antenna arises is known as membranous sockets.

50. Toward the endodermis lies the metaxylem in roots, while the protoxylem occupies a position toward the pith.
