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

• 1st phase: spore producing phase is the sporophyte• 2nd 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

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

• MAKE SURE TO FILL OUT THE GUIDED NOTES DURING THE VIDEO.

• QUESTIONS SHOULD BE IN ORDER• THIS WILL BE A PARTICIPATION GRADE
