Where do prokaryotes store DNA?

Floating in a region of the cytoplasm called the nucleoid.

Cell Membrane

A barrier that surrounds the cell that controls the movement of things going in and out of the cell.

Nucleolus

A structure in Eukaryotic nuclei that makes and assembles ribosomes

Nucleoid

The region where is prokaryotic cell’s DNA is located; inside the cytoplasm

Animal vacuole

Small storage area for waste products

Nucleus

the control center of the eukaryotic cells that contains its DNA

Cytoplasm

the fluid inside the cell where majority of the cell’s chemical reactions occur, and, in eukaryotic cells, holds organelles.

smooth ER

Membrane tubules that don’t have ribosomes. They synthesize lipids, store calcium ions, and detoxify substances.

Plant Vacuole

Large storage area and regulates turgor pressure.

why is it called a “Rough ER”?

its outer surface is studded with ribosomes

Chloroplasts

An organelle found in plant and algae cells where photosynthesis occurs.

Golgi Apparatus

Modifies, sorts, and packages proteins and lipids for transport within or outside the cell. Located in the cytoplasm of eukaryotic cells.

Cytoskeleton

The internal framework of cells that supports its movement and transport.

Cytosol

the fluid part of the cytoplasm

Where do eukaryotes store DNA

Inside the nucleus of the cell

Flagellum

A long whip-like structure used for movement through the cells environment.

Eukaryotes

An organism that has a nucleus and organelles within a memrbane.

Lysosome

An eukaryotic organelle that contains digestive enzymes that break down the “waste” parts of the cell.

Prokaryotes

A cell that doesn’t have a distinct nucleus or other membrane-bound organelles.

Ribosomes

Small structures made of RNA and protein that synthesize proteins.

Rough ER

The location in which the ribosomes are planted and synthesize proteins.

Cell Wall

A rigid layer outside of the cell membrane that provides structure and protection to the cell.

Mitochondria

Produces the cells energy via cellular respiration.
