4. Plantae Multicellular Autotrophs • ________________ • ________________or producers • Cells have _______ _______ and ________________ • Have ________ _________ to prevent water loss • Colors can be vibrant to attract insects and birds for pollination Cell Chloroplasts Wall waxy cuticle
Plantae • Structure (Fill-in chart) A: Leaf • Site of photosynthesis • Flat, so it absorbs the most light • Waxy surface to prevent water loss
Plantae B: Stem • Support for the leaves; used in transport • Stores food • Ex: celery
Plantae C: Roots • Absorbs water and minerals • Anchors (holds) plant in soil • Some plants store food in roots • Ex: potatoes, carrots, turnips
Plantae • Photosynthesis: • Process by which green plants use carbon dioxide, water, and light energy from the Sun to produce glucose (food) and oxygen • Occurs in the plant’s ______ • Provides most of the atmospheric ___________________ • Equation: Sunlight 6CO2+ 6H2O -------- C6H12O6+ 6O2 Chlorophyll leaf Oxygen (O2)
The diagram shows a green plant carrying on photosynthesis. Identify two things shown in the diagram that the plant needs for photosynthesis to occur. ___________________________ ______________________ Identify one product, other than sugar, that results from the process of photosynthesis. ___________ Carbon dioxide (CO2) Water (H2O) Sun Oxygen (O2)
Plantae Making Inferences • Oxygen (02) is produced in photosynthesis. In what process do both plant and animals use oxygen to make energy? Cellular Respiration
Plantae Food • Transportation • Phloem - Transports __________ from the leaves to the rest of the plant • Xylem - Transports __________ and _____________ ___________ from the roots to the rest of the plant water dissolved minerals
Plantae stomata Water • Transpiration • Process of __________ loss through the plant’s ___________. • Stomata: pores in leaves. • Video
Plantae • Gas Exchange • CO2 enters the stomata & O2 (along with H2O) leave the stomata.
Plantae Roots Putting it all Together • Where does water enter the plant? • How does water get to the rest of the plant? • Where in the plant are the sun’s rays absorbed? • Where does CO2 enter and O2 exit the plant? • How does the sugar made in photosynthesis get to the rest of the plant? • What happens to excess water in the plant? Xylem Leaf Stomata Phloem Exits the stomata in the process of transpiration
Plantae Female • Structures: • Pistil - _________ part of the flower that produces the _______ • Stamen - _______ part of the flower that produces the ________________ Eggs Male Pollen grains (male sperm)
A flower has both male and female reproductive parts: The MALE part is called the STAMEN and is made of the anther and filament. The FEMALE part is the PISTIL, and is made of the STIGMA, STYLE, and OVARY. The PETALS attract pollinators. stigma anther style filament ovary with ovules petal Label the FLOWER sepals stem receptacle
Plantae Pollination pollen • _______________ - transfer of _________ from the stamen to the pistil • How? Wind, insects, birds, bats, even water • Video • _______________ - joining of a sperm and an egg cell; occurs after pollination Fertilization
Plantae seed fruit • Once the egg is fertilized, it develops into a _________and the ovary develops into a _________ to protect the seeds • Video • Video 2 • Seeds are dispersed (spread) by ______________________________________________ Wind, water, gravity, and animals
The embryo is the part that will turn into a plant once the seed germinates. The cotyledon stores food for the seed until it is ready to grow. The seed coat protects the seed. embryo seed coat cotyledon Label the SEED
Plantae protective • Structure • Seed Coat :______________ covering • Cotyledon: Stored _______ • Embryo root • First Leaves • _______________ – the development of the seed into a plant • Video food Germination
Practice Which sequence represents the order of development for many plants? (A) seed develops inside fruitseed is dispersedseedgerminatesplant grows (B) seed is dispersedseed develops inside fruitseedgerminatesplant grows (C) seed germinatesplantgrowsseed is dispersedseed develops inside fruit (D) seed is dispersedplantgrowsseedgerminatesseed develops inside fruit • Video A
Plantae Identifying Plants • Conifers- seeds are exposed in a __________ • Angiosperms-____________ plants, seeds are protected in a ________ cone flowering fruit
Let’s discuss... Plants have both male and female parts. Why do you think the male and female parts mature at different times? If they matured at the same time, plants would self-pollinate, decreasing the genetic diversity that would occur if the pollen was transferred to another plant.
Plantae • Ecological Succession: • ____________ in a community that occurs over a _____ period of time • Going from a state of grasses to a forest • Example: Burning of the Long Island Pine Barrens • Video • Video 2 Changes long
