1. An Introduction to Plants Plants come in an amazing variety. These plants have no system for moving water and nutrients throughout the plant. (no plumbing) These plants have tubes that move water and nutrients to all parts of the plant. (they have plumbing)

2. What do you already know?  How do you think non-vascular plants move water and nutrients around. (hint: we studied this process with the elodea plants) It starts with an “O” Osmosis and Diffusion  Which plants, vascular or non-vascular do you think grow the tallest? Explain why? Vascular plants can grow the tallest because they have plumbing to move water and nutrients to different parts.

3. Check it Out What type of plants are these?

4. Nonvascular Plants  These plants are always short like mosses and liverworts because they need to be bathed (sitting or covered) in water.  The water goes directly into each cell.

5. Plants are further divided into plants with seeds and without.  Plants without seeds = All nonvascular plants and ferns, horsetails, and club mosses.  Plants with seeds = Gymnosperms (nonflowering) and Angiosperms (flowering)

6. Complete the concept map using vocabulary from your Powerpoint notes.

7. All Plants Have While there are a huge number of different species of plants all plants have some things in common. 1.All plants make their own food in a process called ________________. 2.All plant cells have _____ ___________ which provide protection and support. 3.All plants have a cuticle. A waxy layer covering the plant surface keeping it from drying out.

8. 4. All plants have a similar life cycle.

11.  What two stages do all plants go through in their life? Sporophyte and Gametophyte Gametophytes create the egg and sperm for reproduction. What process happens in the gametophytes to create the eggs and sperm? _____________ (hint we studied this process in January starts with an M)

12. Roots  Why do plants have roots?  1 To get water  2 To get nutrients  3 To anchor it to the ground (keep it from falling over)

13. Angiosperms (flowering plants) Angiosperms are vascular plants. What does that mean? They have a plumbing system (a vascular system). A system of specialized cells that move water, nutrients and food to all parts of the plants. Individual cells make up tissues which make up ________ which make up _______ _________ which make up the plant. Just like us! Except we’re not plants.

15.  What does xylem transport? Water and nutrients  What does phloem transport? Glucose

16. Assignment: (finish for homework)  On a blank piece of paper draw a model of a tree or plant starting with roots on the bottom, stem or trunk, and finally leaves.  Draw tubes representing the vascular system with different colors for xylem and phloem. (don’t forget a key and/or labels)  Use arrows to show which way they are flowing.
