Plant Structure and Function Concepts

What is the definition of an organ in a living thing?

• A single type of cell that performs a specific function.

• A body part that carries out specific functions and consists of more than one type of tissue.

• A group of cells that look similar and serve similar purposes.

• A specialized cell that can become many different types of cells.

How do stem cells in animals typically differ from those in plants?

• Animal stem cells are always present throughout their life, while plant stem cells are only found in embryos.

• Animal stem cells are unspecialized, but plant stem cells are highly specialized.

• Animal stem cells primarily exist in embryos and are used to form organs, while plants continually produce new organs using stem cells.

• Plant stem cells are responsible for movement, while animal stem cells are responsible for growth.

What is the main job of leaves in vascular plants?

• To provide structural support to the plant.

What is phyllotaxy?

• The process by which plants make their own food.

• The pattern in which leaves grow around a stem.

• The way a plant's roots absorb water from the soil.

What is a key characteristic used to identify a plant part as a stem?

• It is typically green and flat.

• It is primarily responsible for absorbing water.

• It has buds from which new branches or leaves can grow.

• It is always found underground.

What are the two main functions of roots in vascular plants?

• Photosynthesis and reproduction.

• Support and food storage.

• Absorption of water and nutrients, and anchorage.

• Producing flowers and fruits.
