NATURAL SCIENCE FINAL EXAM STUDY GUIDE QUESTIONS
WITH COMPLETE SOLUTIONS ANSWERED GRADED A+
Biology
The study of life and living things
cell membrane
the structure that separates the inside of the cell from the outside of the cell
Cells
the basic units that make up all living organisms
Chloroplast
the organelle in plant cells that capture energy from sunlight to build organic molecules
Chromosomes
DNA containing structures in prokaryotic and eukaryotic cells
Cytoplasm
the part of the cell that is outside the nucleus
DNA
deoxyribonucleic acid, the molecule that stores genetic information in living organisms;
a double-stranded molecule consisting of a sugar-phosphate backbone attached to a
series of nitrogenous bases
Eukaryotes
Organisms whose cells have a nucleus, such as animals and plants
mitochondria
organelles that break down food molecules to provide the energy that cells need to
carry out their function
nucleus
a structure in eukaryotic cells that contains the cells DNA
Organelles
structures in the cytoplasm of eukaryotic cells that have specific functions
, organism
an individual living thing such as a plant or an animal
Prokaryote
organisms whose cells have no nucleus, such as bacteria
active transport
transport across the cell membrane in which energy is required from the cell
ATP
adenosine triphosphate, the molecule that provides energy for most cellular process
cellular respiration
the aerobic, or oxygen-using breakdown of glucose to obtain ATP
enzyme
a protein that lowers the activation energy for a chemical reaction, allowing the reaction
to happen more quickly
mitosis
a type of cell division in which one cell divides into two cells, each of which has the
same genetic information as the original cell
passive transport
transport across the cell membrane that does not require energy from the cell, such as
diffusion and facilitated diffusion
photosynthesis
the process in plants and certain other organisms in which light energy from the sun is
converted to chemical energy in organic molecules
Adaptation
a trait that makes organisms well suited to living and reproducing in their enviorements
artificial selection
the breeding of organism with traits humans like in order to produce offspring with
similar traits
Evolution
inherited changes in living organisms over time
heritable
