Chapter 2: The Body Flashcards
cell
fundamental unit of all living things
- specialized to carry out a function
cell membrane
surrounds and protects the cell
nucelus
controls operation of the cell
- directs cell division
determines structure and function
chromosomes
rod like structures in the cell
how many chromosomes in a cell?
46 (23 pairs)
cytoplasm
all material outside of the nucleus and inside of the cell membrane
- carries on the work of the cell
supplies chemical needs of the cell
mitchondria
sausage shaped bodies that provide principle source of energy for the cell
catabolism
breakdown of large proteins to small proteins
- to release energy in mitochondria
anabolism
process of building up large proteins from small proteins (amino acids)
endoplasmic reticulum
network of canals in the cell
- allows catabolism to happen and release energy
ribosomes
long chains of proteins
metabolism
total chemical process (anabolism + catabolism)
muscle cell
long and slender
- contains fibers that aid in contracting and relaxing
epithelial cell
square and flat
- provides protection
ex: skin and lining cell
nerve cells
long and contains fibrous extensions
