Basic Plant Structure
Happy Monday!
Bellwork: February 17
Copy the 2 sentences and underline key words
The concept of gene flow is demonstrated
when a cow is driven off from its herd, joins
another herd, and reproduces. When the
cow contributes to the gene pool of the new
herd, which of these most likely increases?
A. Natural selection
B. Genetic variation
C. Environmental fitness
D. Reproductive mutations
CO: I will describe the interactions
between systems in plants. I will
describe the reproductive parts of
a plant.
LO: I will write notes. I will discuss
plants with a partner. I will read
about plant reproductive organs.
Science Fact of the Day:
Fingernails grow four times as fast as toenails.
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
Plants
What 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?
Fruit/Vegetable
Broccoli
Cabbage
Carrot
Celery Stalk
Corn Kernel
Garlic
Onion
Potato
Tomato
Zucchini
Part of Plant
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
Complete flowers have four
parts.
Stamen – male part,
include anther and
filament
-
Anther: produces pollen
-
Pollen: plant “sperm”,
fertilizes eggs
Carpel (pistil) –female part,
includes stigma, style and ovary
- Ovary: organ that holds egg, where
fertilization occurs
Sepals – protection for flower during
development
Petals – protection for flower as well as
attracting pollinators
Today’s assignment
• Read the article on plant structure and
reproduction. Highlight or underline the key
words.
• Complete the questions.
• Color the flower according to the directions.
• Label each flower part (ex. A=anther)
• This is a grade due at the end of class.
