Cells & Cell Parts Quiz Study Guide

Vocabulary flashcards for Cells & Cell Parts Quiz.

Cell

Basic unit of life.

Cell membrane

Controls what enters and leaves a cell.

Cell wall

Made of cellulose, gives shape and protection to plant cells.

Nucleus

Contains most of the DNA in the cell and controls all chemistry of cell.

Nucleolus

Produces ribosomes.

Ribosome

Produces proteins.

Endoplasmic reticulum

Network of membranes for transport of materials throughout the cell.

Mitochondria

Produces high energy compounds from food; 'powerhouse'.

Chloroplast

Found in plants only, converts sunlight to energy.

Golgi apparatus

Membrane-bound sacs which package, store and finally move secretions out of the cell.

Lysosomes

Sacs containing digestive enzymes.

Cytoplasm

Material inside the cell.

Nuclear envelope

Controls what enters and leaves the nucleus.

Chromosomes

Found in nucleus, containing genetic information.

Vacuole

Sacs that store water, sugar or pigments.

Cytoskeleton

Gives shape and protection to plant cells.

the 3 parts Cell Theory

-The cell is the smallest living unit in all organisms

-All living things are made of cells

- All cells come from other pre-existing cells.

Prokaryotes

Unicellular organisms that lack membrane-bound organelles and has DNA floating in cytoplasm - no nucleus - tend to be small, simple cells.

Eukaryotes

Eukaryotic cells have membrane-bound organelles, DNA is contained in the nucleus, larger and more complex than prokaryotic cells (Fungi, Animals, Protists, Plants).
