A carrot would be an example of a system. The apical meristem and new growth in the roots are protected by the . Stems of contain a ring of vascular tissue, which includes the xylem and phloem. Stems thicken to support plants growing taller during growth. regulate the exchange of gases in the leaves and help maintain homeostasis. The leaves are often broad and flat because they are the main site of in a plant. The force that allows water molecules to stick to other water molecules is called . The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called . Respond to the following based on your reading. Explain, in your own words, the role of cohesion and adhesion in plant transpiration. What are several adaptations that leaves have undergone? Why do leaves have adaptations in different parts of the world? Choose three nutrients and explain how a plant may look if it has a deficiency in those nutrients.

1. taproot

2. root cap

3. dicot

4. secondary

5. Stomata

6. photosynthesis

7. cohesion

8. transpiration

9. Cohesion describes water molecules sticking together, while adhesion allows them to stick to the sides of the xylem that runs up the plant stem. When water at the top of this chain breaks free and evaporates from the leaf, it pulls on the water molecules behind it. In this way, water molecules are pulled up the plant stem from the roots and into the leaves.

10. Leaves have adaptations such as broad or narrow widths, rounded or pointy tips, and straight versus many vertices. These adaptations allow different species of plants to optimize water retention and photosynthesis in different climates

Plants can show many different deficiencies based on their nutrients. An iron deficiency can leave yellowing or brittle leaves. A potassium deficiency causes leaves to turn yellow at the edges and phosphate deficiencies cause plants to have darker green than normal leaves.

Explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
