mitochondria: <u>powerhouse of the cell</u>
Ribosomes<u>: the places where proteins are synthesized in our cells. </u>
nucleus <u>houses DNA;controls cell</u>
Vacuole: <u>holds waste and fluids from cell</u>
Ribosomes: <u>tiny organelles that contain RNA and specific proteins within the cytoplasm. </u>
Explanation:
Organelles make up the subunits of a cell. There are numerous each with their own function.
Answer:
1. Are usually single-celled.
2. Do not contain membrane-bound organelles
3. Have DNA located in cytoplasm
Explanation:
Prokaryotic cells are single-celled organisms which have the following characters:
1. They lack a true nucleus and hence, they do not have their genetic material enclosed in a nuclear membrane-bound nucleus, rather it is present in the cytoplasm.
2. They lack all the membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.
3. They are usually. very small in size and hence are microscopic.
Examples include all the bacterias.
