In multicellular organisms, specialized cells perform specific functions. Name three types of specialized cells and their primary functions.

1. Muscle cells: Help in movement by contracting and relaxing

2. Nerve cells: Carry messages across the body

3. Blood cells: Transport oxygen, nutrients, hormones, and waste materials.

True or False: A tissue is a group of similar cells working together to perform multiple functions.

False. A tissue is a group of similar cells working together to perform a specific function.

Fill in the blank: Vascular tissues in plants are responsible for transporting ___ and ___ from one part of the plant to another.

Food and water

True or False: Animal tissues are classified into three main types: epithelial, connective, and muscular.

False; animal tissues are classified into four main types: epithelial, connective, muscular, and nervous.

What are the two main categories of plant tissues, and what is the primary function of meristematic tissue?

Meristematic and permanent; meristematic tissue is responsible for growth.

Name three types of Meristematic Tissue.

1. Apical

2. Intercalary

3. Lateral

True or False: Permanent tissues can still divide and are always composed of living cells.

False. Permanent tissues are derived from meristematic tissue that has lost the ability to divide, and they can be composed of both living and dead cells.

Fill in the blank: Collenchyma provides ___ and ___ to growing parts of the plant.

Mechanical support and flexibility

True or False: Sclerenchyma cells are living cells that provide structural support.

False. Sclerenchyma cells are usually dead at maturity and provide strong support due to their thick, tough walls.

Xylem is primarily responsible for transporting ___ and ___ in plants.

Water and minerals

True or False: All cells in phloem are living except for phloem fibres.

True

Name the types of Epithelial Tissue.

1. Simple Squamous

2. Stratified Squamous

3. Cuboidal

4. Columnar (ciliated)

5. Glandular

True or False: Connective tissues are characterized by tightly packed cells with minimal space between them.

False. Connective tissues have loosely spaced cells within a matrix.

What type of tissue is responsible for movement in the body?

Muscular tissue

Fill in the blank: The ____, which are responsible for sending signals, are long extensions of neurons, while the short, branched extensions that receive signals are called _____.

Axon; dendrites
