Which of the following characteristics could be used to classify an unknown pathogen as a virus?

A. It contains DNAB. It has a protein coatC. It has a cell wallD. It causes disease

Look at the diagram below. Which of the following would correctly complete the lytic cycle?

A. Virus kills the host cell.B. Virus parts infect the host cell’s DNA.C. Viral DNA is replicated.D. Parts of virus are assembled to form new virons.

Virus attaches to

the host cell

Virus injects its DNA into the host

Using the cell's

machinery, virus parts

are produced

?Cell lyses

and viruses are

released

CO: I will describe the interactions between systems in plants. I will

describe the reproductive parts of a plant.

LO: I will write notes, discuss plants with a partner, and read about

plant reproductive organs.

Anticipation Guide:Decide if the following statements are

true or false with your partner1. Some plants are single celled organisms2. Plants are prokaryotic and animals are

eukaryotic3. Plants are photosynthetic autotrophs4. Plants have chitin in their cell walls5. Pollination is a part of plant reproduction6. There are carnivorous plants

PlantsWhat makes a plant a

plant?•Plants are eukaryotic

•Plants have cell walls made of cellulose

•Plants make their own energy through photosynthesis

•Plants are multicellular

What plants need to survive…

1. Sunlight

2. Water

3. CO2 & Oxygen

4. Nutrient and water movement

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.

Think-Pair-Share

How do the leaves, stem, and roots work together to help a plant

maintain homeostasis?

Is It a Stem, Leaf, Root, Flower, Fruit or Seed?

Plant Reproductive Structure

• Tomorrow you will be dissecting a flower, identifying the parts, and discussing how plants interact with their environment.

• So let’s take a few minutes to talk about the structure of flowers…

Flower Parts

Stamen – male part; includes anther and filament

- Anther: produces pollen

- Pollen: plant “sperm”, fertilizes eggs

Carpel (pistil) –female part; includes stigma, style and ovary

- Ovary: organ that holds eggs; where fertilization occurs

Petals – protection for flower, as well as attracting pollinators

Sepals – protection for flower during development

Complete flowers have four parts.

Today and tomorrow…

• Read the article on plant structure and reproduction. Highlight or underline the key words.

• Answer the questions.• Color the flower according to the directions.

• We will finish this tomorrow – it is for a GRADE!
