Which of the following did you include in your explanation? Check all that apply.
Identify the plant tissues in the three images.A B C
The tissue that is like the skin is the tissueThe fleshy part of a plant is the tissue.The tissue that is like the cardiovascular system is the tissue.
Choose a plant tissue. Write an explanation of how that tissue’s structure relates to its function. Be specific and detailed.
Xylem is a vascular tissue made of long, hollow cells that join to form continuous tubes. The cells have thick, lignin-reinforced walls, and most mature vessel cells lack end walls. This structure allows water and dissolved minerals to flow efficiently from the roots to the leaves while preventing the tubes from collapsing under the tension created as water moves upward. The thick walls also help support the plant.
Choose a plant organ. Write an explanation of how that organ’s structure relates to its function. Be specific and detailed.
Leaves are broad and flat, giving them a large surface area to absorb sunlight. They contain chloroplasts with chlorophyll, which captures light energy for photosynthesis. Their thin structure allows carbon dioxide to enter and oxygen to leave efficiently. Small openings called stomata permit gas exchange, and guard cells control the openings to limit water loss. Leaf veins contain xylem, which transports water to the leaf, and phloem, which carries sugars made by photosynthesis to the rest of the plant. These structures enable the leaf to perform photosynthesis, exchange gases, and transport materials while reducing unnecessary water loss.

Choose a plant tissue. Write an explanation of how that tissue’s structure relates to its function. Be specific and detailed.
Xylem tissue transports water and dissolved minerals from the roots to the rest of the plant. Its vessel elements are hollow and joined end to end, forming tubes with few obstructions to water flow. Their walls are thickened with lignin, which prevents the tubes from collapsing and also helps support the plant. This structure allows xylem to move water upward efficiently while strengthening the plant.
Choose a plant organ. Write an explanation of how that organ’s structure relates to its function. Be specific and detailed.
A leaf is broad and flat, which gives it a large surface area to absorb sunlight for photosynthesis. Its thin shape allows light and carbon dioxide to reach its cells easily. Many leaf cells contain chloroplasts with chlorophyll, which captures light energy to make sugars. Tiny openings called stomata let carbon dioxide enter and oxygen and water vapor leave; guard cells open and close the stomata to help regulate gas exchange and water loss. Veins contain xylem, which carries water to the leaf, and phloem, which transports sugars from the leaf to the rest of the plant.
