Question

discuss the function of ligament and cardiac muscle fibre and xylem.

Answer 1

Cardiac muscle, also known as heart muscle, is the layer of muscle tissue which lies between the endocardium and epicardium. These inner and outer layers of the heart, respectively, surround the cardiac muscle tissue and separate it from the blood and other organs. Cardiac muscle is made from sheets of cardiac muscle cells. These cells, unlike skeletal muscle cells, are typically unicellular and connect to one another through special intercalated discs. These specialized cell junction and the arrangement of muscle cells enables cardiac muscle to contract quickly and repeatedly, forcing blood throughout the body.

This is a cardiac muscle I don't know ligament

Answer 2

Ligaments are the fibrous connective tissue that connects a bone to another bone at joints
ii) Cardiac muscles fibre are involuntary muscular tissue. The cells here are striated and comparatively short.unlike others , cardiac muscles are branched they can contract without outside stimulation and never gets tired in a person's life time
iii) Xylem cells trans port minerals absorbed by roots from the soil upward to the leaves for photosynthesis
