The cell can be defined as a basic functional unit of life. The term cells is derived from the Latin word and was first observed by a scientist named Robert Hooke in the year 1665.

is usually smaller than a prokaryotic cell
has its DNA concentrated in one area of the cell without a nuclear membrane
is exemplified by bacteria
has a variety of membranous organelles
The diagram shows different types of cells. Which structure do all these cells have?

Cell theory is a result of the contributions of several different scientists, and applies to all living things. Which of the following explains why cell theory will not ever become the law of cells?
Scientific theories are well tested explanations, while laws are well tested descriptions of natural phenomena; one cannot become the other
Cells of different organisms are so divers that it is impossible to come up with a law that would apply to all of them
Because cells undergo change as mutations occur within them, developing anything beyond a cell theory would be impractical.
Scientific theories can only become laws if all possible cases can be tested; it would be impossible to test all living things to see if they have cells
It's easy to take for granted the amazing scientific discoveries of the last few centuries, or even just the last decade, which were once incredible breakthroughs. One of the most fundamental discoveries for modern biology was the discovery of the cell. From the largest cells-nerve cells as long as 39 feet in giant squids, and the single celled ostrich egg weighing in at three pounds-- to the smallest bacterial cells, all cells share common characteristics and are the basic building blocks of all life as we know it. Which invention played the biggest role in the discovery of cells by early scientists?
magnifying glass
lens
eyeglasses
compound microscope
Muscle cells are responsible for obtaining energy so the body can perform voluntary and involuntary movement. Using your knowledge about organelles and muscles, how would a muscle cell differ from other types of animal cells?
The muscle cells would have larger centrioles than other types of animal cells.
The muscle cells would have more mitochondria than other types of animal cells.
The muscle cells would have a larger Golgi apparatus than other types of animal cells.
The muscle cells would have more endoplasmic reticulum than other types of animal cells.
To make a protein, a cell must put together a chain of amino acids in the correct order. First, it makes a copy of the relevant DNA instructions in the cell nucleus, and takes it into the cytoplasm-a bit like taking a photocopy of the instruction manual from the manager's office out to the assembly lines in a car factory. Here the cell decodes the instruction and makes many copies of the protein, which fold into shape as they are produced. Which organelle is the site where amino acids are synthesized into proteins?
1
2
3
4
