Intro to Biology
Units that carry the functions of life
What are cells?
All living organisms are composed of cells
what is cell theory?
The element cycled in the process of photosynthesis and respiration.
What is carbon?
a sphere that contains another sphere called nucleolus
what is nucleus?
cells divide, dna replicates
Organic compounds which are present in and vital to every living cell
what are proteins?
All cells have their own size and shape
what is cell diversity?
form of energy to which sunlight is converted in photosynthesis
What is chemical energy
gelatin-like fluid that lies inside the cell membrane
what is cytoplasm?
where a cell spends 90% of its time in the first three cycle phases
what is interphase?
The building blocks of protein
what are amino acids?
animals, plants, fungi, and protists
what are eukaryotes?
the set of chemical reactions that take place in chloroplasts during photosynthesis.
what is calvin cycle?
ridgid wall made of cellulose,proteins and carbohydrates
normal activities are happening, cellular respiration, protein synthesis and cellular transport
what is G1 phase?
the ability to maintain a constant internal environment in response to environmental changes.
What is homeostasis?
bacteria, differ greatly in structure
what are prokaryotes?
takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere
What is photosynthesis?
A system of membranous tubules and sacs
what is endoplasmic reticulum (E.R.)?
Replication of chromosomes completes, cytoplasmic growth continues
what is G2 phase?
process in which chemical energy is released for cellular use
what is cellular respiration?
Responsible for discovering the "brain" of the cell
what is Robert Brown?
C6H12O6 + O2 --> CO2 + H2O
What is respiration?
phospholipid bilayer with protein that function as channels, markers, and receptors
what is cell membrane?
repeating sequence cellular growth and division during the lifetime of an organism
what is cell cycle
