Science Order and Design; Ch 1 and 2

Flora and Fauna mean what? Flora represents plants Fauna represents animals
To discover the laws of creation and use them for man's benefit is known as... The purpose of science
Angiosperms are? Plants that produce covered and protected seeds. Angi-O-sperm: Yes a seed Gym-NO-sperm: No seed
Gymnosperms are? Plants that DO NOT produce covered and protected seeds.
Cotyledons provide what to the embryo? Nourishment A seedling no longer needs a cotyledon; it can survive on its own.
Living in trees. Arboreal Arbor Day: The day we recognize the importance of trees.
Aquatic means... Living in the water
Sea and ocean life is known as _________ life. MARINE
Terrestrial is: Of the LANDS
Active at night... NOCTURNAL
Active in the day... DIURNAL
Where the organism lives. HABITAT
The sperm cell unites with the egg cell is known as what? FERTILIZATION
When the pollen grain transfers from the stamen to the stigma, we call this process what? POLLINATION
An organism is.... ANY LIVING THING
I introduced the scientific method. Who am I. SIR FRANCIS BACON
Seeds are scattered in two distinct ways. Name them. Mechanical Dispersal Agent Dispersal Mechanical: The plant disperses the seeds independently. An example would be a pod opening and dropping seeds next to the parent plant. Agent requires a separate entity to move the seeds from the parent plant. An example would be the wind or an animal.
I am the largest family of flowering plants. I have two parts to me; the disk flower and the ray flower. COMPOSITE FAMILY SUNFLOWER
The food making process for plants is called... photosynthesis
Sessile means... Leaves that attach directly to the stem.
Compound means: When a leaf has more than one blade joined to the petiole.
In order for a plant to germinate, what must it have? Moisture, oxygen and.... the right temperature.
The composite family is many flowers in one. It has the outer petals known as ____ and the center known as ____. RAY FLOWERS / DISK FLOWERS The sunflower is an example of a composite family.
The mint family has an unusual stem. Explain. The stem is square and stout
The pea family has a nickname. LEGUMES I also return NITROGEN to the soil.
What family has fruits known as grains? GRASS FAMILY
Corms and rhizomes. Do you know what family I am referring too? Amaryllis Family
How are the flower arranged in the parsley family? IN UMBELS DUH!!
I have only one cotyledon, long slender leaves with parallel veins, petals in groups of three and a fibrous root system. What am I? I am a MONOCOT.
I have two cotyledons, leaves that are broad with branching veins, petals in groups of four or five and a taproot system. What am I? I am a DICOT.
I am the second step in Bacon's scientific method. Gather information about the problem.
I am the last part to the scientific method. State the conclusion.
I am the fourth part to Bacon's scientific method. Test the hypothesis by performing an experiment.
After the experiment, what should I do, per Bacon's method? Record and analyze.
Because plants make their own food, they are called.... PRODUCERS
Animals and people that eat plants are called... CONSUMERS
The green pigment in a plant. CHLOROPHYLL
Chlorophyll absorbs light energy that the plant uses to form the chemical ______ Adenosine Triphosphate (ATP)
ATP releases energy to allow the plant to combine _______ and with _______ from the air, to make _________. hydrogen atoms / carbon dioxide (CO2) / Glucose Glucose is a simple sugar which provides energy for the cells of living things.
Cellulose is a what? Carbohydrate Found in the cell wall of plant cells.
Respiration combines ______ with ________ to produce energy. glucose / oxygen Photosynthesis occurs during the day but respiration occurs all day and night.
I support the leaves and flower, transport minerals and water and store food. What part of the plant am I? STEM
My root grows straight down and remains larger than the other smaller roots around me. What type of root am I? Taproot System Think of the CARROT.
A fibrous root system is described as: The primary root remains small and the secondary roots are also small and slender, shooting out in all directions.
Like the strawberry, this type of reproduction involves new growth from the root system but without seeds, flowers, or fruit. What is this called? Vegetative Reproduction
Xylem is: Tissues that carry water and nutrients from the roots hairs to the leaves. The water is used in photosynthesis or released through the stomata. Xylem up!
Phloem is: Tissue that carries sugars from the leaves to the stem and roots to be stored. Phloem down!
Capillarity is also called... Capillary Action The tendency of water molecules to move upward through a tiny space.
Transpiration: Evaporation of water from the leaves Capillary action and root pressure aid in moving water up the stem but transpiration is the true method by which water moves upward to the leaves. The plant cells pull that water into the leaves.
Root hairs: Hair like roots that pull water and minerals into the plant. Water transfers into the roots through osmosis.
An underground structure made of thick, fleshy leaves that surround a short stem. BULB
