Why does a plant need to scatter the seeds far away? (write in complete sentences) What are the characteristics of Nonvascular Plants? • Mosses, Liverworts, Hornworts • Low growing • Can pass materials only from one cell to the next • Cell walls provide support • They get water directly from their surroundings. Gametophyte & Sporophyte What is a seed plant? • All have vascular tissues • Most plants are seed plants (10 to 1) • Seed plants use seeds to reproduce • All seed plants have roots, leaves and stems • In plants what you see are the sporophyte stage. Parts of Seeds • Embryo • Stored Food • Seed Coat. What do seeds need to develop into a new plant? • Light • Water • Nutrients. How can seeds be scattered? • • • • Animals Water Wind Shooting out of plant. What is Germination? • Early Growth Stage of Embryo What role do leaves play in plant? • Leaves capture the sun’s energy and carry out the food making process of photosynthesis Structure of leaf What are the functions of stems? • • • Carry substances between the leaves and roots Support the plant and hold up the leaves Store food. What are the functions of roots? • Anchor plants in the ground • Absorb water and nutrients from the soil • Store food.
