H Bio Ch 6 Part II Flashcards DRAFT

Front

Diagram of a plant cell showing various organelles such as mitochondrion, lysosome, chloroplast, Golgi body, vacuole, endoplasmic reticulum, nucleus, nucleolus, and chromosome.

Back

Ultrastructure of a plant cell covered by a cell wall.

Front

Nucleus

Back

A membrane-bound organelle in eukaryotic cells that contains most of the cell’s DNA. It is enclosed by a nuclear envelope and contains all of the information for the cell to function.

Front

Nuclear Envelope

Back

A double membrane that encloses the nucleus, consisting of a lipid bilayer with specific proteins. It is perforated by pores that regulate molecular traffic into and out of the nucleus.

Front

Chromosomes

Back

Compacted/supercoiled DNA, only visible under a microscope when the cell is about to divide.

Front

Diagram of DNA Structure

Back

Illustrates the structure and organization of DNA into chromosomes.

Front

Nucleolus

Back

A spherical region in the nucleus that makes ribosomes.

Front

Ribosome Pathway

Back

Ribosomes pass through nuclear pores to the cytoplasm.

Front

Diagram of the nucleus

Back

Illustrates the structure of the nucleus and the location of the nucleolus.

Front

Diagram of ribosome structure

Back

Shows the ribosome's large and small subunits and their role in protein synthesis.

Front

Ribosome

Back

A cytoplasmic organelle; site of protein synthesis (makes proteins).
