# Plant Anatomy and Function ## Remembering Key Points * **Plant Organs (Source 2):** Plants consist of organs like flowers, leaves, stems, and roots. These organs are made up of tissues, which in turn are comprised of cells. * **Plant Cell Components (Source 5):** A plant cell is comprised of a cell wall, cell membrane, cytoplasm, nucleus, vacuole, and chloroplasts. Chloroplasts give plants their green color and are responsible for producing nutrients. Plant cells can also contain other structures like colored pigments or starch granules. * **Plant Upright Structure (Source 9):** * **Herbaceous Plants:** Remain upright due to the presence of water in the vacuoles of their cells. * **Woody Plants:** Maintain their upright posture by means of thick cell walls containing woody material. * **Water Transport in Plants (Source 11):** * **Absorption:** Plants absorb water and minerals through their root hairs. * **Transport through Xylem:** Xylem vessels transport water and minerals from the roots to the leaves. * **Transport through Phloem:** Phloem vessels carry water and nutrients to the roots and flowers. * **Transpiration:** The evaporation of water from the leaves drives the upward movement of water in the plant. * **Leaf Loss (Source 13):** * **Seasonal Leaf Drop:** Many trees shed their leaves in the autumn to minimize water loss. * **Leaf Scar Formation:** A protective layer of cork forms over where the leaf was attached, leaving a scar.
