unit7 Flashcards
cell
the smallest unit of life
orgaelles
specialized subunits of a cell that has specific jobs
prokaryotes
cells that do not have a nucleus (acteria,archea)
eukaryotes
cells that do have a nucleas (plants,animals,fungi,prosits
cytoplasm
the fluid inside the cell membbrane that contains all organelles
pili
Tiny hairs on prokaryotes that help cell move and reproduce.
ribosomes
Round structures where proteins are made
flagellum
Tail-like structure that aids in mobility
nucleus
Contains the genetic material of the cell as well as the nucleolus.
nuclealus
Structure inside the nucleus that manufactures ribosomes, the cell’s protein-producing structures.
nuclear envolope
Double-layered membrane that encloses the contents of the nucleus during most of the cell’s 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 cell and create lipids.
rough ER
Studded with ribosomes…aid in protein production and transport
