Exp:C Complex tissue includes 'conducting tissue'. The complex tissues are made of more than one type of cells and these work together as a unit. Xylem and phloem constitute the complex tissues in plants. Xylem functions as a conducting tissue for water and minerals from roots to the stem and leaves.

4 All except (iv)
Explanation:
Exp:D Sclerids are spherical, oval, highly thickened dead cells, with very narrow cavities. Sclereids are found in fruit wall of nuts, the pulp of fruits like guava, pear, and sapota and seed coats of legumes.

Which of the following statement is correct?
1 The collenchyma occurs in layers below the epidermis in monocotyledonous plants
2 Sclerenchyma cells are usually dead and without protoplasts
3 Xylem parenchyma cells are living and thin walled and their cell walls are made up of lignin
4 The companion cells are specialized sclerenchymatous cells
Explanation:
Exp:B The collenchyma occurs in layers below the epidermis in dicotyledonous plants and is absent in monocot plants. - Sclerenchyma cells are usually dead. They become dead and lose their protoplasm after attaining maturity. - Xylem parenchyma cells are living and thin walled and their cell walls are made up of cellulose and pectin. - The companion cells are specialised parenchymatous cells.

Which of the following is an incorrect statement?
1 Nuclear pores act as passages for proteins and RNA molecules in both directions between nucleus and cytoplasm
2 Mature sieve tube elements possess a conspicuous nucleus and usual cytoplasmic organelles
3 Microbodies are present both in plant and animal cells
4 The perinuclear space forms a barrier between the materials present inside the nucleus and that of the cytoplasm
Explanation:
Exp:B Mature sieve tube elements do not have nucleus but have cytoplasm. (Anucleated living cells).
