Pelican Flower (smells really bad)!

Collapsing plant /12/21/15-rare-exotic-amazing- plant- species/ /12/21/15-rare-exotic-amazing-

Hydnora Africana (smells like feces)

Dead Horse Arum Lily (smell is in the name!)

Fly paper plant

Welwitschia mirabilis (Over 2000 years old!)

Water Wheel Plant (Like the Venus fly trap)

Corpse Flower All in a name;-)

Characteristics of plants 1: make their own food 2: cells have cell walls outside their cell membranes 3: reproduce with a two part life cycle

Two part life cycle 1 st phase: spore producing phase is the sporophyte 2 nd phase: the sex-cell (also called gametes) producing phase of a plant is called gametophyte

Two main groups Vascular and Nonvascular Nonvascular: plants that do not have vessels to transport materials throughout the plant Materials are moved around through diffusion and osmosis Most nonvascular plants are small

Vascular Vascular: plants that have vessels to transport materials throughout the plant. Like water pipes in your house Some are very small, some are very large

Read “Focus on George Washington Carver” You are George Washington Carver, and you are veryyyyyy old You decide to write a short biography about your life and accomplishments. Write this biography from his perspective, with a minimum length of 4 paragraphs. Be creative!

Vascular Two groups: Those that produce with seeds and those that do not. Those that don’t use seeds produce through spores Spores are small reproductive cells that can develop into adults without fusing with an adult

BELLWORK

Spores

Vascular Plants Plants that reproduce with seeds are divided into 2 groups: – 1. Gymnosperms: produce seeds but no flowers Include cycads, ginkgoes, gnetophytes, conifers – 2. Angiosperms: produce seeds in flowers Seeds are enclosed in protective cases called fruit All agricultural crops, flowers, shrubs, trees, weeds

Angiosperms

Life spans Vascular plants with seeds are categorized based on their life span. – Annuals: complete their life cycle in one growing season. Annus= year: flowers, herbs, vegetables – Biennials: complete their life cycle in two growing seasons: carrots, celery, etc. – Perennials: live through many growing seasons. Per=through: most trees

Needs of Plants Soil Water Sun’s energy Clean air Space

BELLWORK BRIEFLY WRITE ABOUT A SCIENTIFIC OBSERVATION YOU HAVE RECENTLY MADE

Make a Visual Glossary Read section 5 Define, create an illustration, and give an example (if provided) for each bold term in the section.

LIFE PROCESSES OF PLANTS MAKE A FLIP BOOK 1: TITLE PAGE 2: PHOTOSYNTHESIS 3: CELLULAR RESPIRATION 4: TRANSPIRATION 5: TRANSPORT EACH PAGE SHOULD DEFINE THE PROCESS, GIVE EXAMPLES, AND USE ILLUSTRATION

Bellwork 12-6 #1 What are the three main parts of a plant?

Parts of a Plant 1. Root system: anchor, support, absorb minerals and water 2. Stem: support the plant, transport and store materials. (woody/herbaceous) 3. Leaves: Make food for the plant

What do you think this is?

Taproot Vs. Fibrous root

Stem The stem can actually be underground! Potato!

Leaves Can be simple or compound – On or several piece blade Epidermis-outer layer with waxy coating Mesophyll-inner cells Stomata: openings in a leaf gases can pass through

Epidermis

Mesophyll
