BELLWORK: A. Have out your Notecard Sticker Sheet. Lay out your notecards (definition side up) on your desk 7x5, “ATP” needs to be top left card. B. On your own sheet of paper, write the scenario and the correct tropism to each scenario. 1. You place a lily plant in your windowsill to observe the movement of the flower. 2. The roots of a rosebush absorb the moisture provided by the rain. 3. A vine uses the nearby fence to latch onto. 4. As a seed begins to germinate, the roots grow downward and the stem grow upward.

Essential Question What specialized structures are found in plants? Standard B.10B - Describe the interactions that occur among systems that perform the functions of transport, reproduction, and response in plants PG 116

Anticipation Guide: Decide if the following statements are true or false with your partner 1.Some plants are single celled organisms 2.Plants are prokaryotic and animals are eukaryotic 3.Plants are photosynthetic autotrophs 4.Plants have chitin in their cell walls 5.Pollination is a part of plant reproduction 6.There are carnivorous plants

I. Plantae Kingdom A. Plants are multicellular eukaryotes that have cell walls made of cellulose. B. Plants perform photosynthesis using chlorophyll.

1. Most plants are fully autotrophs, but some are not. 2. Autotrophs are organisms that make their own food.

C. Photosynthesis in Plants 1. Plants use the energy from sunlight to carry out photosynthesis. 2. All plant cells need a constant supply of water because it is used in photosynthesis. LABEL THIS!

3. Plants also need carbon dioxide to carry out photosynthesis (making food) and oxygen to carry out cellular respiration (making energy).

D. Plant Structures and Functions 1. Plants take up water and nutrients through their roots, but make food in their leaves. 2. Plants have special tissues that move water and nutrients up from the soil, and others that distribute the products of photosynthesis (oxygen and glucose) throughout the plant body.

Vascular tissue: specialized tissue used to move water and nutrients throughout a plant.

a) Xylem: carries water upward from the roots to every part of the plant. b) Phloem: transports food produced by photosynthesis. c) The combination of xylem and phloem allows some plants to move water, nutrients, and other dissolved materials from one end of the plant to another.

The three main organs of seed plants are roots, stems, and leaves.

Roots Hold plant in position Absorb water and minerals from the soil Specialized cells (root hairs) to increase surface area for water intake

5. Stems are supporting structures that connect roots and leaves, carrying water and nutrients between them.

Leaves are organs that perform photosynthesis and contain one or more bundles of vascular tissue.

a) The cuticle is a thick waxy layer of the epidermis (surface) that protects the leaf against water loss and injury.

Stomata: openings in the underside of the leaf that allow carbon dioxide and oxygen to diffuse (move) into and out of the leaf. Guard cells: specialized cells in the epidermis that control the opening and closing of stomata.

Let’s learn from the Frizz…

Transpiration is the loss of water through leaves.

Osmotic pressure keeps a plant’s leaves and stems rigid. Wilting results from the lack of water—and therefore of the pressure in a plant’s cells.

Cones produce the seeds of some types of plants (gymnosperms). Flowers hold the seeds of other types of plants (angiosperms).

Think-Pair-Share How do the leaves, stem, and roots work together to help a plant maintain homeostasis?

Plant Parts/Systems Reproductive System = Flower (with male and female parts) Transport System = tissues in stem Nutrient System = Leaf + Root Structural Support System = Stem + Roots All of these parts and systems work together to help a plant maintain homeostasis.
