What is the first statement of the modern cell theory? | All living things are made of cells. |
What is the second statement of the modern cell theory? | Cells are the basic units of structure and function in all living things. |
What is the third statement of the modern cell theory? | All cells come from pre-existing cells. |
All cells can be divided into these two categories based on whether they have a nucleus or not. | Prokaryotic and eukaryotic (Prokaryotic have no nuclues, includes all types of bacteria while eukaryotic cells have a nucleus and make up all of the other types of life except the bacteria) |
Cells with a nucleus are called __ cells. | eukaryotic,
|
TRUE or FALSE: All types of cells have a cell membrane that surrounds the interior of the cell. | TRUE |
TRUE or FALSE: All types of cells have a nucleus where they store their DNA. | FALSE (Only eukaryotic cells store their DNA in a nucleus. The DNA in prokaryotic cells is located out in the cytosol) |
TRUE or FALSE: All types of cells have liquidy substance called cytoplasm that fills the interior of the cell. | TRUE |
TRUE or FALSE: All types of cells have small solid structures called ribosomes that help build proteins. | TRUE |
TRUE or FALSE: All types of cells have DNA that stores the genetic instructions for the organism. | TRUE |
TRUE or FALSE: All types of cells have mitochondria for conducting cellular respiration in order to extract energy from food. | FALSE (Mitochondria are membrane-bound organelles and prokaryotic cells don't have any membrane-bound organelles. Cellular respiration in prokaryotic cells takes place in the cytosol) |
Cells WITHOUT a nucleus (and other membrane-bound organelles) are called ____ cells | prokaryotic |
