What is Biology? |
Biology is the study of life |
|
|
Organisms |
an individual animal, plant, or single-celled life form.
|
|
|
Atoms |
Smallest particular of an element that displays the properties of an element |
|
|
Molecules |
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
|
|
|
Cells |
Smallest unit that displays properties of life; Always contains cytoplasm surrounded by plasma membrane |
|
|
Tissues |
is a group of similar cells that perform a particular function |
|
|
Organs |
Several types of tissues make up
|
|
|
Organ systems |
Group of related organs working together |
|
|
organisms |
individual living things (trees or humans) |
|
|
populations |
Organisms of the same species occupying a certain area |
|
|
Community |
Interacting with one another within the same environment |
|
|
ecosystem |
a biological community of interacting organisms and their physical environment.(in general use) a complex network or interconnected system. |
|
|
biosphere |
is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. |
|
|
Metabolism |
is the sum of the reactionsinvolved in these processes
|
|
|
Photosynthesis |
which occurs in organisms such as plants, is responsible forproducing the organic molecules that serve as food for most organisms.
|
|
|
Reproduce |
To produce a new individual of the same type |
|
|
Growth |
Increase the number of cells and or the size of the cell |

All living organisms share basic characteristics |
(1) are organized
(2) acquire materials and energy, (3) are homeostatic, (4) respond to stimuli, (5) reproduce and grow, (6) have an evolutionary history |
|
|
What is a eukaryote |
A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota.
|
|
|
What is a Prokaryotes |
Prokaryotes are unicellularorganisms that lack organelles or other internal membrane-bound structures . Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-strandedDNA located in an area of the cell called the nucleoid.
|
|
|
What is a single cell? |
Bacteria |
|
|
What are multicelluar |
A human (many different types of cells) |
|
|
True or false Life is connected from the atomic level to the biosphere
|
True |
|
|
True or false? Cell is the basic unit of life |
True |
|
|
true or false The sum of all life on the planet is called the biosphere.
|
True |
|
|
Mutations |
A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation.
|
|
|
Evolution |
is the process by which a population changes over time.
