Vocabulary: vascular system, transpiration

Review

1. Plants are multicellular with cells that have a nucleus and a cell wall. They are producers and have a two-stage life cycle.

2. A leaf is suited for photosynthesis, having cells with many chloroplasts at its surface. Xylem brings in water. Stomata let in carbon dioxide. The cuticle keeps water in. Phloem transports sugars.

3. xylem and phloem

4. Stomata, regulate the amount of carbon dioxide, oxygen, and water vapor that enters and exits the plant.

5. Soft-stemmed plants have green stems, with cells that have chloroplasts. Woody stems are brown or grey; the cells do not have chloroplasts.

6. Plants differ in height. Some are soft-stemmed. Some are woody. They live in many different environments. Yet the basic structure is the same: roots, stems, leaves. All rely on photosynthesis to get needed energy and materials.
