Unit 7 cell structure and function Flashcards
cell
The smallest unit of life
organelles
specialized subunits of a cell that have a specific job
prokaryotes
cells that do not have a nucleus (bacteria,archaea)
eukaryotes
cells that do have a nucleus (plants, animals, and fungi
cytoplasm
The fluid inside the cell membrane that contains organelles
pili
Tiny hairs on prokaryotes that help the cell move and reproduce
ribosomes
round structures were proteins are made
flagellum
tail like structure that aids in mobility
nucleus
contains the genetic material of a cell as well as the nucleolus
nucleolus
structure inside the nucleus that manufactures ribosomes the cells protein producing structures
nuclear envelope
double layered mambrane that encloses the contents of the nucleus during most of the cells life cycle
nuclear pores
small holes within the nuclear envelope that regulate the passage of molecules between the nucleus and cytoplasm
Endoplasmic Reticulum
A transport system that extends from the nucleus and Moves materials around the cell. (Can be smooth or rough depending on if it contains ribosomes.)
smooth ER
contains no ribosomes and helps detoxify the cells and create liquids
Rough ER
Studded with ribosomes…aid in protein production and transport
