Introduction to Tissues

The video tutorial explains how a single cell divides into trillions of genetically identical cells, yet differentiates into over 200 types with specialized functions. It compares unicellular and multicellular organisms, highlighting the need for cell differentiation. The tutorial discusses specialized cells forming tissues, and the differences between plant and animal tissues. It covers plant tissue types, including meristematic and permanent tissues, and animal tissue types, such as epithelial, muscular, connective, and nervous tissues.

What is the primary reason for cell differentiation in multicellular organisms?

• To increase genetic diversity

• To eliminate unnecessary cells

• To perform specialized functions

• To reduce the number of cells

How are tissues categorized in the context of plants and animals?

• Based on their color

• Based on their size

• Based on their functions and growth patterns

• Based on their location in the body

Which type of plant tissue is responsible for continuous growth?

• Permanent tissue

• Meristematic tissue

• Sclerenchyma

• Collenchyma

What is the function of xylem in plants?

• Transporting food

• Transporting water and minerals

• Aiding in reproduction

• Providing mechanical support

Which type of animal tissue is involved in voluntary and involuntary movements?

• Connective tissue

• Nervous tissue

• Epithelial tissue

• Muscular tissue

What is the primary role of epithelial tissue in animals?

• To provide protection

• To store nutrients

• To transmit signals

• To aid in movement

Which animal tissue type is responsible for control and coordination?

• Muscular tissue

• Connective tissue

• Nervous tissue

• Epithelial tissue
