Question 1. Tina observed a permanent slide of a plant tissue with thin walled cells, loosely packed with large intercellular spaces. Identify the tissue.
  1.    Parenchyma tissue
  2.    Epithelial tissue
  3.    Sclerenchyma tissue
  4.    Aerolar tissue
 Discuss Question
Answer: Option A. -> Parenchyma tissue
:
A
Parenchyma cells have thin walls.They are live cells. They are usually loosely packed,andlarge intercellular spacesare found in this tissue.Therefore, the slide consists of parenchyma cells.
Tina Observed A Permanent Slide Of A Plant Tissue With Thin ...Sclerenchyma is the tissue which makes the plant, hard and stiff. Aerolar tissue and epithelium are animals tissues.
Question 2. The amount of dead tissue is more in animals than in plants.
  1.    True
  2.    False
  3.    Ability to move
  4.    Complexity to perform a function
 Discuss Question
Answer: Option B. -> False
:
B
The amount of dead tissue is more in plants than animals. Manyessential functions in plants are attributedto dead tissues. Dead tissue provides support andmechanical strength to plants, e.g., sclerenchyma. Apart from this, the main conducting tissue in plants, xylem is mostly composed of dead cells.
Question 3. Which of the following tissue forms the inner lining of blood vessels?
  1.    Nervous tissue
  2.    Epithelial tissue
  3.    Connective tissue
  4.    Muscular tissue
 Discuss Question
Answer: Option B. -> Epithelial tissue
:
B
The covering or protective tissues in the animal body are epithelial tissues. Epithelium covers most organs and cavities such as the skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules.
Question 4. Which among the following is lined with squamous epithelium?
  1.    Oesophagus
  2.    Intestine
  3.    Kidney tubules
  4.    Salivary gland
 Discuss Question
Answer: Option A. -> Oesophagus
:
A
Squamous epithelial cells are extremely thin and flat. They form a delicate lining. Oesophagus, lining of mouth, lining of blood vessels., etc are covered with squamous epithelium. Here the transportation of substances occurs through a permeable membrane.
Which Among The Following Is Lined With Squamous Epithelium?...
Question 5. Which of the following pair forms the vascular bundle?
  1.    Parenchyma and sclerenchyma
  2.    Xylem and parenchyma
  3.    Xylem and phloem
  4.    Phloem and collenchyma
 Discuss Question
Answer: Option C. -> Xylem and phloem
:
C
Xylem and phloem together form the vascular bundle. They are called conducting tissues. Vascular or conductive tissue is a distinctive feature of the complex plants. Parenchyma, collenchyma and sclerenchyma on the other hand form the simple permanent tissue (ground tissues).
Question 6. Which tissue is responsible for the increase in the girth of the stem?
  1.    Apical meristem
  2.    Cambium
  3.    Intercalary meristem
  4.    Xylem
 Discuss Question
Answer: Option B. -> Cambium
:
B
Cambium (lateral meristem)is situated below the bark and is responsible for the increase in the girth of the stem or root.
Which Tissue is Responsible For The increase In The Girth ...

Question 7. Which among the following is the correct set of examples of tissues?
  1.    Amoeba, WBC and RBC
  2.    Blood, phloem and muscle
  3.    Liver, lungs and kidney
  4.    Xylem, heart and platelets
 Discuss Question
Answer: Option B. -> Blood, phloem and muscle
:
B
A group of similar cells with a common origin specialised to perform a common function are called tissues. E.g., Blood, phloem, muscle, xylem, etc.Various tissues organise to form an organ. Organs, such as heart, lungs, stomach, kidneys, skin, liver, etc are made up of two or more types of tissues organised to serve a particular function. The organs organise to form an organ system.
Question 8. Deepa observed two slides of plant tissues. She was told one contained parenchyma cells, while the other slide had sclerenchyma cells. How can she confirm the slide with sclerenchyma cells?
  1.    By the presence of cells with a large central vacuole.
  2.    By the presence of green colour pigment called chlorophyll.
  3.    By the presence of cells with thick cell walls.
  4.    By the presence of cells with many nuclei.
 Discuss Question
Answer: Option C. -> By the presence of cells with thick cell walls.
:
C
Sclerenchyma is a dead simplepermanent tissue in plants. The walls of sclerenchyma cells are thick due to the deposition of a complex sugar called lignin. For example, husk of a coconut. Parenchyma tissue on the other hand, is a living tissue. It consists of relatively unspecialised cells with thin cell walls.
Question 9. Based on which of the following criteria, plant tissues are categorised into meristematic and permanent tissues? 
  1.    Ability to undergo photosynthesis
  2.    Ability to divide actively
  3.    Ability to move
  4.    Complexity to perform a function
 Discuss Question
Answer: Option B. -> Ability to divide actively
:
B
Plant tissues are broadly classified into meristematic and permanent tissues, based on their ability to divide. Meristematic tissues are group of cells, which have the ability to divide. This tissue consists of small, cuboidal anddensely packed cells, which keeps on dividing to form new cells.The tissues, which are derived from the meristematic tissues, are calledpermanent tissues. They are the tissues, which have lost their ability to divide as they have attained their mature form.
Question 10. Identify the type of simple permanent tissue.
(i) The cells of this tissue are dead.
(ii)The cell walls are thickened due to lignin.
 
  1.    Parenchyma
  2.    Collenchyma
  3.    Aerenchyma
  4.    Sclerenchyma
 Discuss Question
Answer: Option D. -> Sclerenchyma
:
D
Sclerenchyma is the tissue which makes the plant hard and stiff. The husk of a coconut is made of sclerenchymatous tissue. The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin.
