Goblet Cells

Cells that secrete mucus and prevent dirt, dust, and smoke from entering the lungs.

Cilia

Hair-like structures responsible for moving mucus along the trachea to trap foreign particles.

Red Blood Cells

Cells that transport oxygen throughout the body; oxygen binds to hemoglobin.

Muscle Cells

Cells made up of muscle fibers that contract to cause movement of bones.

Fat Cells

Cells made up of a large vacuole for storing excess fat as chemical energy.

Skin Cells

Tightly fitted cells that form a layer covering the outer body, protecting from the environment.

White Blood Cells

Cells that act as the 'soldiers' of the blood, engulfing bacteria and fighting infections.

Nerve Cells

Thin and long cells with a branching network that conduct electrical signals throughout the body.

Bone Cells

Cells that collect calcium from food to assist in body growth and repair of bones.

Sperm Cells

Cells that contain the genetic information of the male organism.

Photophores

Cells with the ability to release light, important for vision, protection, and attracting mates.

Xylem

Plant cells important for the movement of water and dissolved minerals throughout the plant.

Phloem Cells

Cells responsible for moving dissolved sugars throughout the plant, serving as a food source.

Storage Cells

Cells that are compartments storing excess energy in the form of starch.

Epidermal Cells

Cells on the root hairs of plants, important for water absorption.

Photosynthetic Cells

Cells containing chloroplasts that convert sunlight into food via photosynthesis.

Guard Cells

Cells essential for controlling and regulating water within the plant.
