Seed Plants (Pg 262-271) 1. What are the two characteristics of seed plants? They have vascular tissue (tubes), and they both use pollen and seeds to reproduce. 2. What are the two kinds of vascular tissue (tubes) in seed plants? Phloem and xylem 3. Vascular tissue Job Xylem the tubes where water enter and move upward into the stems and leaves Phloem the tubes through which food moves 4 Vascular plants contains __pollen_____, tiny structures that will later become sperm cells. 5. What is a seed? A structure that contains a young plant inside a protective covering 6. What are the three main basic parts of a seeds? Describe each part. 1.An embryo (baby plant) is a zygote, or fertilized egg. 2.The stored food, which is stored outside the embryo. 3.A seed coat, which protects the seed from drying out. 7. What is seed dispersal? What are the 4 ways that seeds can disperse? Scattering of seeds is called seed dispersal Dispersal by wind, water, animals, and force. 8. What is germination? A process in which the embryo begins to grow and push out the seed 9. What is the job of roots? What part of the root helps to do this job? 1.Roots anchor a plant in the ground, 2.absorb water minerals from the soil, and 3. sometimes store food. The root cap helps do its job. carrot, radish 10. What are the two kinds of roots? Fibrous and taproot 11. What is the job of a stem? 1.Carries substances between the plants roots and leaves, 2.provides support for the plant 3.holds up the leaves so they can be exposed to the sun. 12. What are annual rings? The patterns of circles that represents a trees yearly growth. 13. What is the job of the leaves? Captures the suns energy and carries out the food making process of photosynthesis. 14. Which cells of the leaves are responsible for photosynthesis? The ones located near the leafs upper surface. These cell contain chloroplast. 15. What is used and what is made during photosynthesis? Used Carbon dioxide and water Made Sugar(food) and oxygen . 16. What is transpiration? Which structure of leaf prevent water loss The process by which water evaporates from a plant’s leaves. The cuticle and stomata in the leaf prevents water loss.
