Cell Structures – Vocab Review


Nucleus

Nucleus

  • Part of the cell that contains DNA & RNA.

  • Controls cell’s growth & reproduction.

Lesson 27 cell structures

DNA

  • Deoxyribonucleic acid.

  • Contains the instructions needed to make proteins that perform important functions for an organism (examples: develop, survive and reproduce).

Lesson 27 cell structures

RNA

  • Ribonucleic acid.

  • Carries the genetic instructions from DNA in nucleus to cytoplasm where proteins are made.

Cell membrane plasma membrane

Cell Membrane(Plasma Membrane)

  • Surrounds the cell.

  • Controls what can come into or leave the cell.

Cytoplasm

Cytoplasm

  • Fluid that fills the cell.

Mitochondria

Mitochondria

  • Provides cell with energy.

Endoplasmic reticulum

Endoplasmic Reticulum

  • A membrane network used for transport within the cell.

Vacuole

Vacuole

  • Membrane bound organelle that contains fluid. Can be used for storage.

Other parts flagellum

Other Parts: Flagellum

  • Long projection that is used to help the cell move (locomotion)

  • Only found in some cell types

Other parts cilia

Other Parts: Cilia

  • Many short, thin projections that can be used to help the cell move (locomotion)

  • Only found in some cell types
