2.1 What are Organisms and Their Components? (Pgs. 37-41)
organisms are living things with components that biotechnologists work directly with
they are the raw materials of biotechnology
cells are the smallest unit of life that makes up all living organisms, these can be manipulated in many ways
Escherichia Coli (E.Coli) is a bacterium that is commonly used by biotechnology companies for the development of products
multicellular composed of more than one cell
● frost resistant strawberry plants or endangered animals
any fields of biotechnology require a thorough understanding of cellular composition
● Biochemistry (chemistry of all living things) cytology (cell biology) anatomy
(structure) and physiology (function)
What is The Living Condition?
the earth is home to a tremendous diversity of living things
biologists estimate there are 20 million different species
an organism exhibits “the characteristics of life”
● activities include: growth, reproduction, response to stimulation, respiration (breakdown of food molecules), production of waste
● organisms composed of only one cell are unicellular
○ E.Coli, protozoans (amoeba), and algae
○ must use a microscope in order to view these organisms
What are the Levels of Biological Organization?
plants, animals, and fungi are all examples of multicellular organisms, grouped into functional units
● tissues (muscular or nervous) and organs (skin, liver, and stomach) are a couple functional units that perform different jobs to endure the whole organism can survive
● cells require energy in order to create proteins
atoms →molecules →organelles →cells →tissues →organs →organisms
Eukaryotic cells have a membrane bound nucleus (plants, animals, fungi & protist) and are made up of tiny units
protist are from the kingdom of protozoans (slimes & certain algaes) organelles are specialized microscopic factories, each w/ a specific job in the
