5. system - the body system that works to control and coordinate all bodily functions and includes nerve cells (neurons), the brain and the spinal cord.
6. cell - the photosynthetic cells found in leaves of plants.
7. system - the body’s largest organ that consists of skin, hair, and nails.
8. system - body system that removes waste and excess water from the body and includes the lungs, skin, kidneys, and urinary bladder.
10. - the sticky, receptive surface at the top of a flower’s female reproductive organ where pollen grains land and begin the process of fertilization.
13. system - the body system involved in breathing and gas exchange and includes the nasal passages, the pharynx, the larynx, the epiglottis, the trachea, bronchi, the lungs, and the diaphragm.
17. system - body system that functions as a communication system and includes the pituitary gland, the thyroid gland, the parathyroid gland, the thymus gland, the pineal gland, the pancreas, the adrenal glands, the ovaries, and the testes.
18. - organism’s reaction to a stimulus (a change in an organism’s environment)
19. - part of the plant that supports leaves, flowers, and fruits, transports water and dissolved substances from the roots to other parts of the plant.

1. system - a network of tissues and vessels that carry blood and lymph through the body and includes the heart, arteries, veins and capillaries.
2. system - body system that works to protect the body from infection and disease and includes the skin, mucus, and white blood cells.
3. - vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
4. system - the above ground part of a plant, including stems, leaves, flowers, and fruits, which is responsible for photosynthesis, nutrient transport, and reproduction.
9. - plant structure that develops into a seed when fertilized.
10. - a tiny opening on the surface of a plant leaf or stem, surrounded by guard cells , which control the exchange of gases like carbon dioxide and oxygen between the plant and its environment.
11. gravitropism - the growth of plants in respect to gravity; roots are positive because they grow down and stems are negative because they grow up against gravity.
12. - the growth movement of a plant in response to light
14. - organ of a plant that anchors it into the ground and takes in water and nutrients.
15. system - the body system involved in producing offspring
16. cell - one of a pair of cells that function in the opening and closing of a plant’s stomata by changes in their shape.
