The Kingdom Plantae
Across
- 1. structure of seed plant embryo that stores or absorbs food for the developing embryo; may become the plant first leaves when the plant emerges from the soil.
- 3. a thin, rootlike structure that anchors a moss and absorbs water and nutrients for the plant.
- 5. a waxy, waterproof layer that covers the leaves of most plants.
- 11. scaly structures produced by some seed plants that support male or female reproductive structures and are the sites of seed production; receptor cells in the retina adapted for sharp vision in bright light and color detection.
- 14. a food making process where plants use sunlight, water, and carbon dioxide to make food and oxygen.
- 16. a green pigment found in the chloroplast of plant, algae, and some bacteria cells.
- 17. any of the microscopic openings or pores in the epidermis of leaves and young stems.
- 19. earliest stage of growth and development of both plants and animals; differences and similarities among embryos can provide evidence of evolution.
Down
- 2. in plants, the outmost layer of cells that covers and protects all parts of the plant; in humans and some other animals, the outermost protective layer composed of an outer layer of dead cells and an inner layer of living cells.
- 4. a period when an organism’s growth or activity stops.
- 6. structures in a plant cell that contain chlorophyll to help a plant make food.
- 7. a system of tube-like structures inside a plant that transport water, mineral, and food.
- 8. most abundant type of plant cell; spherical cells with thin, cells walls and a large central vacuole; important for storage and food production.
- 9. the leaf of a fern plant.
- 10. regions of actively dividing cells in plants
- 12. tiny particles produced by seed plants that contain sperm cells.
- 13. broad, flat plant organ supported by the stem that grows upward toward sunlight and traps light energy for photosynthesis.
- 15. vasuclar plant tissue composed of tubular cells joined end to end; transports sugars from the leaves to all parts of the plant.
- 18. the growth response of a plant toward or away from a stimulus.
- 20. plant organ that absorbs water and minerals from the soil transports those nutrients to the stem, and anchors the plant in the ground; may also serve as food storage organs.
