Points to remember! correct answersAll 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 answersthe basic functional unit of an organism
DNA correct answerscontains all the instructions needed to direct a cell's activities
Mitosis correct answersreplication of a cell & its DNA
Life science (or biology) correct answersis the study of all living things, from plants to animals and
humans.
A biologist is someone who- correct answersstudies 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 answers-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 answersevery organism from the smallest, single-celled bacterium to the
largest animal on earth, the blue whale
, All organisms have similarities, correct answerssuch 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 answersthe 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 answers1. 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 answerscells 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 answersmeaning 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 answersthe 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 answersWATER
Nucleus correct answersCells must create DNA, the genetic material which allows a cell to replicate, &
this DNA in a specific region in the cell called the nucleus.
The nucleus & its DNA hold inside correct answersAll of the information needed to function & create
another cell.
Cells have "Organelles" correct answersWhich are structures (of which the nucleus is one) within the
cytoplasm that preform certain specialized duties.
