# Chapter 4 Science Study Guide ## Test Date: December 10, 2024 1. Plants make their own food. Most of this food is made in the plant's leaves. 2. Leaves contain various tissues. Each kind of tissue has particular kinds of cells that perform a specific role. 3. Epidermis tissue, spongy tissue, leaf opening (pore), and vessel tissue are parts of a plant's leaf. 4. The process of photosynthesis takes place in the cells' chloroplasts. 5. Plants perform photosynthesis using carbon dioxide, water, and sunlight to make oxygen and sugar for food. 6. Sugar moves from the leaves to other parts of the plant where it is stored and later provides energy. It also forms cellulose, a chemical that makes up the strong cell walls. 7. Cellular respiration is the process by which plants get the energy they need to repair their parts. 8. Stems are plant organs that hold leaves, flowers, and fruit on the plant. 9. Vascular plants have xylem and phloem to carry materials. 10. Roots store food, anchor a plant, and absorb water and minerals from the soil. 11. Taproots and fibrous roots are two types of root systems. A taproot is a large root that grows straight down. Fibrous roots grow out in all directions. 12. In a flowering plant, the stamen makes pollen and the pistil makes the egg, which are responsible for plant reproduction. 13. Sepals are the small modified leaves that cover a bud. 14. All plants reproduce. 15. Plants pass information from one generation to the next through DNA. 16. Wind, water, or living things may move pollen from one stamen to the pistil of a plant or plants. 17. A fertilized egg cell grows into seed with one whole set of DNA, half from each parent. 18. Seeds consist of three main parts: seed coat, embryo, and endosperm. 19. A seed has one or two special structures called cotyledons. Monocots are seeds of plants with one and dicots are seeds of plants with two. 20. Temperature and moisture are conditions that influence when a seed will sprout. 21. A plant's growth is partly affected by its DNA and its environment. 22. Gravitropism, phototropism, and thigmatropism are three types of tropisms. Gravitropism is the growth of a plant or plant part because of gravity. Phototropism is a plant's reaction to a source of light. Thigmotropism is a plant's growth in response to touching an object.
