  1. Parenchyma

  2. Xylem

  3. Epidermis

  4. Phloem

A Correct answer
Explanation

Simple permanent tissue: Made up of only one type of cells. Parenchyma, collenchyma, sclerenchyma.

Complex permanent tissues: Made up of many kinds of cells.Xylem and pholem.
Parenchyma: It is most simple and unspecialized tissue which is concerned mainly with the ordinary vegetative activities of the plant.
So, the correct answer is 'Parenchyma'.

Multiple choice biology plant tissues tissues of plants levels of organisation in plants structural organization in living organisms

Match the following and choose the correct option from below

A. Meristem (i) Photosynthesis, storage
B. Parenchyma (ii) Mechanical support
C. Collenchyma (iii) Actively dividing cells
D. Sclerenchyma (iv) Stomata
E. Epidermal tissue (v) Sclereids

  1. A-(i), B-(iii), C-(v), D-(ii), E-(iv)

  2. A-(iii), B-(i), C-(ii), D-(v), E-(iv)

  3. A-(ii), B-(iv), C-(v), D-(i), E-(iii)

  4. A-(v), B-(iv), C-(iii), D-(ii), E-(i)

B Correct answer
Explanation

A. Meristem: It includes group or cluster of cells which remain in a continuous state of division or retain their power of division.

B. Parenchyma: It performs the function of storage of reserve food materials, storage of water in succulents, Buoyancy and gaseous exchange in water plants.
C. Collenchyma: It is the chief supporting tissue in young dicotyledonous stems. The tissue has the capacity to expand and gives tensile strength to the body.
D. Sclerenchyma: It consists of thick-walled dead cells. It is of two main types: Fibres and Sclereids. Sclereids are short and possess extremely thick lamellated lignified walls with long tubular simple pits.
E. Epidermal tissue:  The tissue originates from the outermost layer of the apical meristem. It has epidermis, cuticle and wax, Stomata, Trichomes. Singular of stomata is stoma. A typical stoma is microscopic and usually consists of two kidney-shaped guard cells surrounding a pore.
So, the correct answer is 'A-(iii), B-(i), C-(ii), D-(v), E-(iv)'.
