GED Science Exam Questions and
Answers Graded A+
Points to remember! - Correct answer-All living things have several things in
common. The cell is the basic functional unit of a living organism. Ecosystems are
home to thousands of organisms, each playing a necessary role. ABOUT 40% THE
GED SCIENCE QUESTIONS WILL BE ABOUT LIFE SCIENCES.
Cell - Correct answer-the basic functional unit of an organism
DNA - Correct answer-contains all the instructions needed to direct a cell's
activities
Mitosis - Correct answer-replication of a cell & its DNA
Life science (or biology) - Correct answer-is the study of all living things, from
plants to animals and humans.
A biologist is someone who- - Correct answer-studies organisms, or living things,
of which there are over 1.5 million different types. Biologist study their structures,
their life cycles, and their relationship to their environment.

,Scientist have come up with a way to separate the living from the non-living: -
Correct answer--Has a life cycle (from birth to death)
-Has the ability to move or grow
-Has the need to find sources of energy as in feeding
-Has the ability to respond to stimuli, or something in the environment, that causes
a change in behavior
-Has the ability to reproduce
-Made up of cells
Life science covers - Correct answer-every organism from the smallest, single-
celled bacterium to the largest animal on earth, the blue whale
All organisms have similarities, - Correct answer-such as needing energy to grow,
interacting with their surroundings, and producing offspring. (No matter how big
or small, all of these organisms are alike in that they are composed of cells.
The Cell - Correct answer-the cell is the basic functional unit of an organism,
meaning that each cell has the potential to fulfill all the functions of that organism.
Cells also must arise from other pre-existing cells
4 pts of a Cell - Correct answer-1. The first part of a cell is the membrane

, 2. The second part of a cell is the cytoplasm
3. The third part of a cell is the nucleus
4. The fourth part consists of the many organelles (ALL CELLS HAVE FOUR
DISTINCT PARTS)
Cell mambrane - Correct answer-cells are surrounded by a thin covering, which
separates the cell from its environment.This membrane is called the "cell
membrane" (or plasma membrane) it acts as a barrier or wall.
Cell membranes are semipermeable, - Correct answer-meaning that they will allow
some substances to move both into and out of cells through the cell membrane.
This allows the cell to take in the required nutrients and expel any waste products.
Cytoplasm - Correct answer-the inside of the cell, is the semi-liquid substance in
which all of the internal "organs" of the cell are dissolved. (this is where much of
the biochemical activity of the cell occurs)
The main component of cytoplasm is - Correct answer-WATER
Nucleus - Correct answer-Cells must create DNA, the genetic material which
allows a cell to replicate, & this DNA in a specific region in the cell called the
nucleus.
