This organelle is where the DNA of the cell is found.

What is the nucleus?

100

The system responsible for breathing.

What is the respiratory system?

100

This type of muscle tissue pulls on your bones.

What is skeletal muscle?

100

The thin waxy coating on the upper surface of the leaf.

What is the cuticle?

100

In this phase of the cell cycle, the chromosomes line up down the middle of the cell.

What is metaphase?

200

These organelles are produced in the nucleolus, and in turn they are the producers of protein.

What are ribosomes?

200

The integumentary system contains this organ, the largest in the human body.

What is skin?

200

This tissue could informally be called the "lining tissue".

What is epithelial tissue?

200

This upper part of the leaf is made of long, vertical cells that are arranged in a "fence" like way.

What is the palisade mesophyll? 

200

The cell spends 90% of its life in interphase where it grows, performs its function, and does this very important process.

What is DNA replication?

300

These organelles are the "cleaner uppers" of the cell.

What are lysosomes?

300

The main responsibilities of this system include drainage and fighting infections.

What is the lymphatic system?

300

Tissues are groups of cells that work together to perform a function. Therefore, blood counts as a tissue. Which category of tissues does blood fall under?

What is connective tissue?

300

Water flows into the leaf through this type of vascular tissue.

What is xylem?

300

The final part of the cell cycle, when the cell splits into two.

What is cytokinesis?

400

Found in plant cells only, photosynthesis happens in these organelles.

What are chloroplasts?

400

This system contains the pancreas and many glands such as the pituitary gland and adrenal glands.

What is the endocrine system?

400

Your fingertips have a really high concentration of these types of neurons.

What are sensory neurons?

400

After producing glucose, the leaf transports it to other parts of the plant through these vascular tissues.

What are phloem?

400

The process of "cleaving" begins in this phase of mitosis.

What is telophase?

500

These organelles help process and package proteins and lipids in the cell. 

What are golgi bodies?

500

Inside the organs of this system, red blood cells are created.

What is the skeletal system?

500

This specific subtype of tissue is made of flattened cells forming a watertight barrier.

What is squamous tissue?

500

Gases enter and exit the leaf through these openings on the underside of the leaf.

What are stomata?

500

This is where a pair of duplicated chromosomes are attached together.

What is the centromere?
