  1. Study guide for Chapter 21 Test • Ribosomes • ER • Nucleus • Chloroplast • Golgi body • Vacuole • Chromoplasts • Cell wall

  2. 9. Most common plant cells, Found throughout the plant. Collenchyma – Most common in younger tissues of leaves and shoots.

  3. Sclerenchyma – Found in parts of the plant that are no longer growing.

  4. 10. Xylem and phloem make up the vascular tissue of the plant. Xylem transports water and minerals from the roots to the leaves. Phloem transports glucose made during photosynthesis from the leaves to the roots. 11.

  5. 12. Primary – Growth in length – Apical meristem is responsible Secondary – Growth in width (‘girth’) of plant – Lateral meristem is responsible. 13. Bark Pith Early wood (lighter color) Tree ring/ One year of growth Latewood (darker color)

  6. 14. Early wood – lighter in color, time of growth when there was plenty of water, nutrients available. Late wood – darker in color, time of growth when conditions were harsh (drought), growth was slower. 15. Blade

  7. A – Contains large air cavities, help with movement of O2, CO2 and water vapor. May contain chloroplasts. • B – Waxy, prevents water loss • C – Control the opening and closing of the stomata. • D – Contains a lot of chloroplasts. Main function is photosynthesis. • E -Openings that allow for gas exchange (water vapor, O2, CO2). • F – Contains xylem and phloem, xylem carries water and minerals, phloem carries glucose. Forms the veins of the leaf.
