Animal Tissues : Connective | Tissues | Assessment | English | Grade 9

The tissue that connects various organs of the body with each other is called ______.

• Epithelium tissue

• Connective tissue

• Muscular tissue

• Nervous tissue

Answer explanation

The tissue that connects the various organs of the body with each other is called connective tissue.

The matrix of cartilage is composed of:

• Proteins and sugars

• Proteins and enzymes

• Proteins, sugars and calcium

• Proteins and lipids

Answer explanation

The matrix of cartilage is composed of proteins and sugars.

Which connective tissue provides the framework to animal body?

• Blood

• Cartilage

• Bones

• Adipose connective tissue

Answer explanation

Bones provides the framework to animal body

Identify the connective tissue shown in the following figure.

• Adipose tissue

• Areolar connective tissue

• Lymph

• Bone

Answer explanation

In the given figure, the cells of connective tissue are labelled as osteocyte. Osteocytes are the cells of bone. Hence the given figure is of the bone.

Which of the following statement is incorrect?

• Blood and lymph are the fluid connective tissue.

• Tendon are highly flexible.

• Areolar connective tissue helps in repair of tissues

• Adipose tissue serves as a source of energy.

Answer explanation

Blood and lymph are embedded in a fluid matrix. That's both are fluid connective tissue. Tendon are strong, fibrous and tissue with limited flexibility. Areolar connective tissue fills the space inside organs and supports the internal organs and also helps in repair of tissues. Adipose tissue stores fat in the form of fat globules and fat is source of energy. Therefore adipose tissue serves as a source of energy. Hence statement in option 2 is not correct.

The animals that live in polar region have high amount of:

• Bones

• Areolar connective tissue

• Adipose tissue

• Blood

Answer explanation

We know that adipose tissue acts as a heat insulator. That's why fatty individuals feel less cold as compared to slim individual. Therefore animals that live in polar region have to tolerate excessive cold conditions. So they have high amounts of adipose tissue in their body.

During car driving Sohan had an accident. After X-ray it was determined that his two bones of a joint were dislocated. Which of the following may be the possible reason?

• Muscle break

• Tendon break

• Fracture in bone

• Ligament break

Answer explanation

Here, in an accident the bones of a joint were dislocated. That means the bone is not broken. So there is no fracture in bone. We know the two bones are connected with each other by the ligament. Therefore, ligament is broken then the bones can be dislocated. So ligament break can be the reason of bone dislocation. Muscle and bone are connected with each other by the tendon. So if tendon breaks, then the two bones will not be dislocated. Similarly muscle break can not cause bone dislocation. Therefore option 4 is the right answer.
