All living things are
made of cells
Rough Endoplasmic Reticulum
makes proteins and packages them for secretion.
Stimulus? Response?
Stimulus: change in environment
Response: a change in the organism
Chloroplast
Photosynthesis occurs here (plant cells)
Homeostasis
need of an organism to stay stable.
Cells are the
basic unit of life
Ribosomes
make proteins.
Positive Feedback
Intensifies the response.
Central vacuole
Storage center
Dynamic Equilbrium
is maintained but isn't always the same (stays in a range.)
Two types of cells
Prokaryotic and Eukaryotic
Smooth ER
make Lipids
Negative feedback
counter response to return to a set point.
Prokaryote cell
No nucleus, not membrane bound, binary fission, made of peptideglycan and an example is bacteria
Stimulus
change in enviorment
Organelles are
specialized structures within the cell that work together to help the cell function.
Golgi Apparatus
gets vesicles of protein from the ER, processes,sorts, and ships proteins where needed.
Ex: Human body temp and water concentration.
Eukaryote cell
Yes nucleus, yes membrane bound, mitosis, fungi,animals, plants, protists
Response
a change in the organism
Differance between Animal and Plant Cells
Animal cells have centrioles, cilia, flagella, and lyosomes.
Plant cells have chloroplast, central vacuole, cell wall.
Centrioles
Help cell divide by pulling chromosomes apart
Positive feedback example
Ex: child birth and fruit ripening.
Lyosomes
Break down dead stuff
Concentration
amount of solute dissolved in colvent
