What is Taxonomy?
The branch of biology concerned with identifying, naming, and classifying organisms is part of systematics
Who developed the system of giving organisms a two-part name called binomial nomenclature?
What hierarchial levels of classification are used to name an organism in binomial nomenclature? Which one is written first?
- 1.) Genus - can contain many species
- 2.) Species - refers to one species within that genus
To what genus does the timber rattlesnake (Crotalus horridus) belong?
List the eight levels of hierarchal classification from most inclusive to least inclusive.
Domain-Species- Genus- Family- Order- Class- Phylum- Kingdom
major factor separates the members of the Domain Eukarya from Eubacteria
Write the Kingdom of the organisms that fit the
- a. Multicellular,
- autotrophic, eukaryotic organism
- b. Multicellular,
- have cell walls containing chitin, produce spores
- – Kingdom
- c. Multicellular,
- heterotrophic, eukaryotic organism that must ingest their food
- d. Unicellular,
- prokaryotic organisms that can live in extreme conditions
What is the name given to the life cycle of plants
which includes a sporophyte generation and a gametophyte generation?
Alteration and Generation
Flowers are just modified what?
List the major parts of a flower and discuss the
roles of each (be sure to include reproductive and non-reproductive parts)
- 1) Sepals – Protects the flower bud
- 2) Petals – attract pollinator
- 3) Stamens – pollen grain develops
- 4) Carpel – Contains the stigma, style, and ovary
what plant part does the seed develop?
Carpel - the ovary becomes a seed
What structure develops into a fruit in angiosperms?
To what structure on the flower is pollen transferred during pollination?
What are the major photosynthetic organs of the
plant? In what tissue of these organs does photosynthesis take place?
The leaves and the mesophyll; leaves
What is the function of the waxy cuticle on the surface of plant leaves?
To prevent water loss
What are some major differences between angiosperms and gynposperms?
- 1) Flower dispersal as
- seeds, flowering land plant-seeds are born within a fruit
- 2) A type of woody seed
- plant, seeds are not enclosed by a fruit, and usually born in cones
In what structure of the flower is the pollen produced?
What are stomata? What is their function?
Little openings that allow gas exchange
What structures on the roots of plants help to increase surface area for absorption?
List the major differences between monocots and
dicots (eudicots). Be sure to include: leaf venation, vascular bundles, flower
parts, seed leaves, and types of roots.
- 1) Monocot – members have 1
- embryonic leaf, parallel-veined leaves, scattered vascular bundles, flower
- parts in three or multiples of three, and root xylem and phloem in a ring
- 2) Dicots – members have 2
- embryonic leaves, leaves form a net pattern, vascular bundles in a distinct
- ring, flower parts in fours or fives and their multiples, and root phloem
- between arms of xylem
Give an example of some taproots we eat.
Carrots, beets, turnips, and radishes
