Yes, all cells are made from previous cells. This is stated in the cell theory. However, if you are asking whether cells are composed of tiny cells within them, the answer is no. The smaller structures inside cells are called organelles.
Because all cells are roughly the same size. This means that bigger animals are made of more cells than smaller animals. (If bigger animals had the same number of cells as smaller animals then the cells they were made of would have to be bigger in proportion to those that smaller animals were made of - and they are not)
Molecules are smaller. Sub atomic particles are even smaller
An atom is smaller than a cell, and a molecule is smaller than both atoms and cells. Cells are composed of molecules, which in turn are made up of atoms.
No, tissues are made up of cells and viruses are not even cells.
An atom is several orders of magnitude smaller than a cell. Even the smallest of cells is composed of trillions of atoms.
Elodea cells are smaller
Molecules are made up by cells. As a result, cells are smaller than molecules. Atoms are even smaller than cells since they make them up.
No. In fact they are not living and not even made of cells
Yes, blood is composed of formed elements and the liquid matrix called plasma. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Cella are the smallest unit of life; with that said cells are made up of "organelles" much in the same way humans are made up of organs. Beyond that all cells and their organelles are simply made up of fibres and lipids and to get any smaller we'd have to look at molecules.
Yes, they may be smaller than humans but they are made of cells just like humans.
One prokaryote ate another smaller prokaryote, causing the smaller prokaryote to become the nucleus and the larger one is the cell itself.
