The image shows a setup of an experiment. A student takes a leafy green Balsam plant and places it in Eosin solution. The solution is a red coloured dye. After 4 hours, the student observes that the red colour appears on the parts of the plant body. Which type of tissue is responsible for these changes?

• xylem as it helps in the movement of water from roots to stem and leaves

• phloem as it helps in the movement of water from roots to stem and leaves

• xylem as it helps in the movement of water from leaves to roots and stem

• phloem as it helps in movement of water from leaves to roots and stem

Which animal tissue acts as a protective tissue of an animal's body?

• Muscle tissue

• Nervous tissue

• Connective tissue

• Epithelial tissue

Muscles that are present in the eye help the eyelids to blink when dust particles enter the eye. Which animal tissue signals the muscles in the eyelid to blink?

• (a)connective tissue

• (b)epithelial tissue

• (c)muscular tissue

• (d)nervous tissue

Which type of epithelial tissue will help in the movement of particles such as mucus out of the respiratory tract?

• 
• 
• 
• 

Skin is the outermost layer of the body which provides protection from mechanical injuries as well as helps in secretion of sweat and oils. Which type of epithelium is the skin likely composed of to facilitate all the mentioned functions?

• (a)epithelium having flat surface

• (b)epithelium arranged in many layers

• (c)epithelium with irregular shaped cells

• (d)epithelium with hair-like projections for particle movement

The image shows the structure of a specialized epithelium.

What will be the likely function of this epithelium?

• (a)secretion of substances

• (b)protection from wear and tear

• (c)restrict movement of the tissue

• (d)transport of substances across permeable surface

The image shows the microscopic view of lung alveoli.

What can be concluded about the function of the epithelium based on its structure?

Options:

1. (a) Multiple layers of alveolar cells form different tissues.

2. (b) A single layer of alveolar cells supports easy transport of gases.

3. (c) The layer of alveolar cells provides protection to the lungs.

4. (d) Multiple layers of alveolar cells facilitate movement of particles.

• (a)multiple layer of the alveolar cells forms different tissues

• (b)single layer of alveolar cells supports easy transport of gases

• layer of alveolar cells provides the protection to the lungs

• (d)multiple layer of the alveolar cells facilitates movement of particles

What should be the likely structure of a connective tissue whose framework supports the organs of the body?

• (a) multiple layers like the skin

• (b) bundle of neurons like nerve

• (c) strong and non-flexible like bones 107

• (d) relaxing and contracting like muscles

A student studies the structure of areolar connective tissue found in blood vessels. Which statement about the structure of the tissue is correct?

• (a)compact structure of fibers increases the strength

• (b)low number of fibers provide rigidity to the structure

• (c)loose arrangement of fibers fills the space inside organs and support it

• (d)random arrangement of fibers running in same direction provides elasticity

The image shows the location of a connective tissue. What will be the likely function of this connective tissue?

• (a)allow bones to move

• (b)provides strength to the bones

• (c)prevent the bones from bending

• (d)connects one bone with the other bones
