Science Unit 2 Cells

A network of sac-like structures and tubes in the cytoplasm of a cell.

a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

Powerhouse of the cell

A sac-like organelle that stores water, food, and other materials.

A jellylike fluid inside the cell

Control center of the cell

A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.

Separates the interior of the cell from the outside environment.

Responsible for protein synthesis

a plastid that contains chlorophyll (green pigment) and in which photosynthesis takes place

Allowing liquids or gases to pass through it.

Not permitting passage (especially of fluids)

Ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.

The movement of solvent (water) through a semipermeable membrane from the side of lower solute concentration to the side of higher solute concentration. (Only solvent moves)

Movement of molecules from an area of high concentration to an area of low concentration. (Both solvent and solute moves)

A single celled organism

Made up of more than one cell

Microtubule based hair like organelles that extend from the surface of almost all cell types of the human body.

Whip like tails found in one-celled organisms to aid in movement

A temporary growth on a cell that allows it to be mobile, almost like a little foot. (false foot)

The process by which food, in the form of sugar (glucose), is transformed into energy within cells.

Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

A group of cells that possess a similar structure and perform a specific function

A part of an organism that is typically self-contained and has a specific vital function

A group of organs that work together in performing vital body functions.

A type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands

bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.

A body tissue that contracts or shortens, making body parts move.

A body tissue that carries messages back and forth between the brain and every other part of the body

The tissues that are present in the outermost part of the plant (leaves, stem, roots, etc.) that are responsible for protecting the plant body.

Plant tissue in leaves used to make food by photosynthesis using sunlight.

Moves water and nutrients through the plant

It supports the body, facilitates movement, protects internal organs, produces blood cells and stores, releases minerals and fat, and is the frame of the body.

It makes you move, breathe, makes your heart beat

Made up of blood vessels that carries blood away or towards the heart. The system carries oxygen, nutrients, and hormones to cells, and removes products such as carbon dioxide

the network of organs and tissues that help you breath. The system helps your body absorb oxygen from air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections

your body's command center. It controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development

breaks down food so nutrients can be absorbed by the blood and transported to all cells. It also disposes solid waste.

removes waste from the body. These wastes include, water, CO2, nitrogen, salts and heat.

body system that consists of the skin, hair, nails, and exocrine glands. This system forms a barrier between the internal environment and the external environment. This system has many functions, including protection, regulation of body temperature, and sensory reception.

The glands and organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body.

The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases.
