Identify the simple tissue from the following.
biology plant tissues tissues of plants levels of organisation in plants structural organization in living organisms

  1. Parenchyma

  2. Xylem

  3. Epidermis

  4. Phloem

Show answer
Correct Option: A
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'.

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

  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)

Show answer
Correct Option: B
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)'.


Which of the following is a parasitic plant?

  1. Cactus

  2. Saliva

  3. Cuscuta

  4. Cucumber

Show answer
Correct Option: C
Explanation:

Cuscuta is a parasitic plant. It is lack chlorophyll hence it appears as yellow tubular structures and obtains its food from its host mirabel.

If the contents of a leaf tissue are a carefully fractioned, which of the  fraction could be called alive?

  1. Mitochondria

  2. ER

  3. Cell wall

  4. Ribosomes

Show answer
Correct Option: B
Explanation:

Mitochondria contains DNA. Thus. it is called semiautonomous organelle and it can survive the fractionation process.

The study of tissue is known as

botany plant tissues introduction to tissue tissues - "the teams of workers" introduction to tissues

  1. Histology

  2. Cytology

  3. Dermatology

  4. Cardiology

Show answer
Correct Option: A
Explanation:

The tissue is the group of cells from the common origin and performs a specific function and its detailed study is called as histology. Dermatology is the branch of medicine concerned with the diagnosis and treatment of skin disorders. Cardiology is the branch of medicine that deals with diseases and abnormalities of the heart. Cytology is the branches of biology and medicine concerned with the structure and function of plant and animal cells. Thus, the correct answer is option A.

Which of the following involves in sectioning of tissues?

  1. Immunofluoresence

  2. Stain

  3. Microscope

  4. Paraffin block

Show answer
Correct Option: D
Explanation:

The study of tissue is known as histology or, in connection with disease, histopathology. The tissues are studied by the use of paraffin block in which tissue is embedded and then sectioned, the histological stain and then observed under the microscope. Therefore, the correct answer is option D.
