12/3 - 7th Grade Agenda Learning Objective: Learn about nonvascular & vascular plants Collect HW: Reading & Notetaking p.175 - 178 Collect HW: Signed grade printout Video: Test your brain Textbook Reading 371 - 374 HW: Reading & Notetaking p.179 – 182 Reminder: Bring a flower on 12/4 & 12/5 for flower dissection lab. ( 5 Points) Reminder HW: Science Fair Topic due 12/13 & 12/14 (10 Points) Reflection • Prompt: What are two differences between nonvascular and vascular plants? (write in complete sentences) Why does the lemon looks yellow and leaves look green? • Because lemon reflects yellow light • Plant leaves reflect green light. Which color of light is absorbed by chlorophyll? • Chlorophyll absorb blue and red light Why do leaves turn red and yellow in the autumn? • Chlorophyll masks the color of most accessory pigments during most of the year • In cool temperatures, chlorophyll breaks down and the colors of accessory pigments can be seen. 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. Reminder Homework for 12/4 & 12/5 HW: Bring a large flower in a plastic bag w/ your name on it. that we will observe in class: Best to bring a Lilly Next best is to bring a large flower where you can see the pistil and stamen. You can go to a florist and ask them of any old flower that they are going to throw away 5 Points Science Fair Project (85 Points) • Science Fair Topic & Hypothesis due 12/13 & 12/14 • Final Project due 2/23 & 2/24 • Need to come up with a question and hypothesis. • Next, you need to conduct an experiment and publish results.
