Anatomy of cell Flashcards
1
Q
Cell membrane
A
- thin, outermost structure of human cells
- selectively permeable
- lines within cell wall in bacdterial cells
2
Q
Cell wall
A
- outer most layer that mains shape and protection
- gram pos or gram neg
- humans do not have it
3
Q
Nucleus
A
- largest organelle
- controls cell’s function
- contains chromosomes
4
Q
Nuclear membrane
A
- surrounds the nucleus
- has pores that allow for compounds to move in/out of cell’s nucleus
5
Q
Cytoplasm
A
- contains other organelles
- components are water, proteins, ions and nutrients
6
Q
Ribosome
A
- contributes to protein synthesis (building of proteins from basic components)
- supports the protein chains as (RNA) builds them)
7
Q
Endoplasmic reticulum
A
- provides passageways for various substances w/n cytoplasm
8
Q
Mitochondrion
A
- gives the cells energy
- cells can have more than one depending on the need
9
Q
Lysosome
A
- digestion
10
Q
Centriole
A
- helps in cell division
11
Q
Golgi apparatus
A
- synthesizes carbohydrates
- sorts proteins the ribosome is supprting
- has some storage functions prior to preparing some substances for removal from cells
12
Q
Peroxisome
A
- contains enzymes
13
Q
Flagellum
A
- helps cell move
14
Q
Cilia
A
- helps cell move through various tracts and paths in the body
