Across
- 4. The main body or stalk of a plant that typically rises above the ground and supports leaves, flowers, and fruits.
- 5. A characteristic that helps an organism survive and reproduce in its environment.
- 7. The process by which plants exchange gases, taking in carbon dioxide (CO2) and releasing oxygen (O2).
- 10. A green pigment found in the chloroplasts of plants that is responsible for the absorption of light to provide energy for photosynthesis.
- 12. The process in which a seed sprouts and begins to grow into a new plant.
- 13. The main photosynthetic organs of a plant, often flat and green, where most of the photosynthesis process occurs.
- 14. A type of plant tissue that transports water and dissolved nutrients from the roots to the rest of the plant.
- 15. Small openings on the surface of plant leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen and water vapor.
- 17. The process by which seeds are spread or distributed away from the parent plant to help in the growth of new plants in different locations.
- 19. The part of a plant that typically lies below the surface of the soil and absorbs water and nutrients.
Down
- 1. A plant that produces seeds that are not enclosed within a fruit, often found in coniferous trees like pine.
- 2. Another type of plant tissue that transports food (usually in the form of sugars) produced through photosynthesis from the leaves to other parts of the plant.
- 3. An organism that can produce its own food using energy from sunlight or inorganic substances. Autotrophs are also known as producers as they form the base of the food chain by providing energy for other organisms.
- 6. A flowering plant that produces seeds enclosed within a fruit.
- 8. The transfer of pollen from the male reproductive organs to the female reproductive organs in plants, leading to fertilization.
- 9. The growth or movement of a plant in response to a stimulus, such as light (phototropism) or gravity (geotropism).
- 11. Substances that provide nourishment essential for the growth and maintenance of a plant.
- 16. The process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
- 18. The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
