ATI TEAS 7 FULL STUDY GUIDE (SMART
EDITION): SCIENCE - CELL STRUCTURE,
FUNCTION, AND TYPE
The smallest structural units and basic building blocks of living things. -
☑️Cells.
Who discovered the first cells in the mid-eighteenth century? -
☑️Robert Hooke.
The cell theory consists of these 3 parts. -
☑️1. All living things are composed of one or more cells.
2. Cells are alive and represent the basic unit of life.
3. All cells are produced from preexisting cells.
T/F: More than a trillion cells and at least 200 different types of cells exist in the human body. -
☑️True.
Where is DNA in a prokaryotic cell? -
☑️Floating in the cytoplasm.
There is no nuclei.
What are organelles? -
☑️Specialized structures with a specific cellular function.
Function of ribosomes. -
☑️Aid in protein synthesis.
Function of pili. -
☑️Aid in cellular adhesion.
The 2 most common prokaryotes. -
☑️Bacteria and archaea.
What is a cell membrane? -
☑️A double layer that separates the inside of the cell from the outside environment.
It is semi-permeable.
What is a nucleus? -
☑️A membrane-bound organelle that contains the genetic material, such as DNA, for a
cell.
Where is the nucleolus located and what is its function? -
