yes they are. all plants have heart muscles.
Cardiac cells make up cardiac tissue.These cells are only found in heart.
Cardiac muscle is only found in the heart.
plants and animal cells
Yes, cardiac muscle cells do have an endoplasmic reticulum. The endoplasmic reticulum in cardiac muscle cells helps in the synthesis, folding, and transport of proteins that are essential for the functioning of the cell.
cells and prokaryotes
Chloroplasts are found ONLY in plant cells - they are used for photosynthesis.
In plants
yes
HIV cells are not found in plants. Forms of the HIV virus only exist in Primates and Felines.
ribosomes :)
Intercalated discs are found in cardiac muscle tissue, specifically at the junction between adjacent cardiomyocytes (heart muscle cells). They contain specialized structures that facilitate communication and coordination between cells, allowing for synchronized contraction of the heart.
Potassium is found in the cardiac cells as well as the extracellular fluid surrounding the heart.
