Bio 2.1.6 Tissues Organs and Systems

What are multicellular organisms made up of?

Different cell types organized into tissues, organs, and organ systems.

What is a tissue?

A group of cells that are specialized to work together to carry out a particular function.

What type of epithelium lines the alveoli in the lungs?

Squamous epithelium, which is a single layer of flat cells.

What is the function of ciliated epithelium?

To move substances, such as wafting mucus along the trachea.

What are the three types of muscle tissue?

Smooth, cardiac, and skeletal muscle tissue.

What is cartilage?

A type of connective tissue that shapes and supports structures like joints, ears, and the windpipe.

What is the primary function of xylem tissue in plants?

To transport water and provide support.

What does phloem tissue transport in plants?

Sugars around the plant.

What is an organ?

A group of different tissues that work together to perform a particular function.

What tissues are found in the lungs?

Squamous epithelial tissue, ciliated epithelial tissue, elastic connective tissue, and vascular tissue.

What is an organ system?

A group of organs that work together to perform a specific function.

What organs are part of the respiratory system?

Lungs, trachea, larynx, nose, mouth, and diaphragm.

What organs are involved in the circulatory system?

Heart, arteries, veins, and capillaries.

What is the role of palisade tissue in leaves?

To carry out photosynthesis.

What is the function of epidermal tissue in leaves?

To prevent water loss.

What is the structure of skeletal muscle tissue?

Made up of bundles of elongated cells called muscle fibers.

What are chondroblasts?

Cells that secrete an extracellular matrix to form cartilage.

What are sieve cells in phloem tissue responsible for?

Transporting sap through perforated end walls called sieve plates.

What type of cells make up xylem vessel cells?

Dead cells that help transport water.

What is the extracellular matrix?

A jelly-like substance containing protein fibers secreted by cells.

How do tissues contribute to organ function?

Different tissues work together to perform specific functions within an organ.

What is the relationship between organs and organ systems?

Organs are combined to form organ systems that perform broader functions.
