100

This is the chromosome-containing organelle of an eukaryotic cell.

Nucleus

100

These are used as guide tubes for movement of materials, for separation of chromosomes during cell division, and for maintaining the shape of cells by assuming a compression-resisting role.

Microtubules

100

This organelle functions as the site of protein synthesis.

Ribosome

100

This is a membrane-enclosed sac taking up most of the interior of a plant cell.

Central vacuole

100

This is how DNA exists when the cell is not dividing.  It is made up of DNA plus proteins.

Chromatin

200

This organelle serves as the site of cellular respiration.

Mitochondrion

200

These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of cell shape.

Microfilaments

200

This is where metabolism of carbohydrates and detoxification of drugs occur.

Smooth ER

200

This is an organelle found in plants that absorbs sunlight and uses it to drive synthesis of organic compounds.

Chloroplast

200

This is made up of a phospholipid bilayer and is the outer boundary of an animal cell.

Plasma Membrane

300

This organelle is essentially a membrane-enclosed bag of hydrolytic enzymes.

lysosome

300

These help maintain the shape of the cell by bearing tension (resisting pulling forces) and are made up of a diverse family of proteins.

Microfilaments

300

This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide.

Peroxisome

300

This is a short cellular appendage specialized for locomotion.

Flagellum

400

This organelle consists of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum.

Golgi Apparatus

400

MCAT Question: A cell has normal ribosomes and mRNA but cannot produce ATP efficiently. Which organelle is the most likely site of dysfunction? 

Mitochondria

500

This is an extensive membranous network in eukaryotic cells that is composed of ribosome-studded and ribosome-free regions.

Endoplasmic reticulum

500

MCAT Question: Put these in the correct order for a protein being secreted from the cell: Golgi | plasma membrane | RER.

RER → Golgi → plasma membrane
