Unlike animal cells, plant cells are surrounded by one of these structures made of cellulose.

We often refer to microscopic prokaryotic organisms by this name.

Though research involving these unspecialized cells remains controversial, they play a very important role in our body's growth, development, and healing.

The inner portion of the plasma membrane has this property, meaning it repels water.

Biological buffers help us maintain homeostasis by stabilizing this measurement in each part of our body.

DNA is contained in this organelle, referred to as the control center of the cell.

Prokaryotic cells lack membrane-bound organelles, such as these cell powerhouses that convert glucose to ATP.

The epidermis, which is the top layer of this organ, is made up of smooth, flat cells that keep our body safe from pathogens.

The plasma membrane is mostly composed of these two-tailed molecules.

Diffusion of water across a membrane.

Ribosomes use directions from RNA to synthesize these important and versatile macromolecules.

Prokaryotic cells are surrounded by three layers, the outermost being this sticky, protective layer.

AKA Erythrocytes, these disc-shaped cells transport oxygen throughout your body.

Proteins, and carbohydrates can shift and float in the loosely connected lipid layers. This model of the membrane is often referred to as the Fluid this artful term.

In this type of diffusion, transport proteins help larger molecules cross the lipid bilayer.

These organelles are the location of photosynthesis in plant cells.

These hairlike structures on the surface of prokaryotic cells are used for attachment or sexual reproduction.

The two human sex cells are known as the ova (egg cells) and these male gametes.

When water is leaving a cell because of a concentration gradient, this term describes the surrounding solution.

This structure inside the nucleus is responsible for creating our ribosomes.

Animals and plants both have these storage organelles, but they are much larger in plant cells and help provide structural integrity.

Most of a prokaryote's DNA is found in a large, central nucleoid, but some of it is isolated in these small rings.

These branching cells transmit signals from your brain to the rest of your body and back.

The cell membrane is imbedded with two types of proteins: transport proteins and these proteins with attached carbohydrates.

Inventor of the compound microscope and namer of cells.
