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

Muscle cells help in movement by contracting and relaxing, nerve cells carry messages across the body, and 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

Plants have supportive tissues primarily made of ___ cells, while animals rely on ___ tissues for movement.

Dead; living specialized

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.

What are the two main types of plant tissues?

Meristematic and permanent tissues

Fill in the blank: Meristematic tissue is located in the ___ regions of the plant.

Growing

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

I am a complex tissue that helps carry food from leaves to other parts of the plant. What am I?

Phloem

Epithelial tissues are primarily responsible for ___ and ___ in the animal body.

Covering organs and controlling material exchange

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
