What are the 3 tenets of the cell 1) All organisms are composed of one or more
theory? cells
2) The cell is the structural unit of life
3) Cells can arise only by division from a pre-
existing cell
Fundamental properties that are - Cells are highly complex and organized
shared by all cells (9)? - Possess a genetic program
- Can reproduce
- Acquire and use energy
- Carry out chemical reactions
- Engage in mechanical activities
- Respond to stimuli
- Capable of self-regulation
How is energy passed from one Light energy is converted by photosynthesis into
organism to the next? chemical energy that is stored in energy-rich
carbohydrates. These carbs are source of energy
for animal cells.
, Common features between PROK PM, genetic info (DNA), similar mechanisms for
and EUK (9) transcription/translation, shared metabolic
pathways (glycolysis, TCA), ATP, photosynthesis
mechanisms, protein synthesis, proteasomes,
cytoskeletal filaments built of proteins similar to
actin and tubulin
EUK only features nucleus, complex chromosomes (DNA +
histones), cytoplasmic organelles, complex
cytoskeletal system/flagella/cilia, phagocytosis,
diploidy, sexual reproduction, mitotic spindles
two domains of PROK cells archae and bacteria
(archae are more closely related to EUK)
EUK specialized cells are formed differentiation
by
As cell size increases, surface decreases
area/volume ratio ___
Surface area/volume ratio Larger the cell (cytoplasmic volume) = longer it
importance in cell size. takes to move things in/out, generate messages
required by cell
- Too big = SA not sufficient to support cell
activities
viruses - obligatory intracellular means they cannot produce unless present within
parasites a host cell
are viruses considered living no; inability to reproduce/metabolize without
organisms? host cells
