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?
Carolus Linnaeus
-
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?
Crotalus
-
List the eight levels of hierarchal classification from most inclusive to least inclusive.
Domain-Species- Genus- Family- Order- Class- Phylum- Kingdom
-
What
major factor separates the members of the Domain Eukarya from Eubacteria
and Archeabacteria?
Cell Wall
-
Write the Kingdom of the organisms that fit the
following descriptions:
- a. Multicellular,
- autotrophic, eukaryotic organism
- -Kingdom
- plantae
- b. Multicellular,
- have cell walls containing chitin, produce spores
- – Kingdom
- Fungi
- c. Multicellular,
- heterotrophic, eukaryotic organism that must ingest their food
- –Kingdom
- Anamalia
- d. Unicellular,
- prokaryotic organisms that can live in extreme conditions
- -Protists
-
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?
Leaves
-
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
-
- From
what plant part does the seed develop?
Carpel - the ovary becomes a seed
-
What structure develops into a fruit in angiosperms?
Ovary
-
To what structure on the flower is pollen transferred during pollination?
Stamens
-
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?
Anther
-
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?
Root hairs
-
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
