Plants Flashcards
Know the terms
What are Autotrophs?
An organism that have the capabilities to make its own food.
What is the difference between Angiosperms and Gymnosperms?
Angiosperms can produce flowers and fruits while gymnosperms cannot.
What is Algae, and what does it lack?
A unicellular or simple multicellular photosynthetic organism.
They lack multicellular sex organs.
What is the cuticle of a plant, and what is its purpose?
Wax or fatty layer on a leave.
Used to prevent extreme water loss.
Diploid vs. Haploid
Diploid- Has 2 sets of chromosomes (2n) Sporophyte generation
Haploid-Has only 1 set of chromosomes (n) Gametophyte generation.
What is Haplodiplontic?
A life cycle stage, when both haploid and diploid are multicellular.
Ecosystem
Consist of living and non-living organisms.
Types:?
Gamete
A usually one-celled reproductive body that can grow into a new organism without uniting with another cell. Spores are haploid (having only a single set of chromosomes).
Gametangium
A cell or organ in which gametes are formed in.
Name the two Vessel Elements?
Xylem-Carries water
Phlem- Carrier sugars and nutrient’s
Taxonomy
The history of classifying living things.
A molecule dissolved in solution.
Solute
Transpiration
The loss of water in plants, used to control plants temp.
Where does plants lose water from and what is the process called?
Stoma and Transpiration
A haploid reproductive cell, usually unicellular.
Spore
What is sporangium?
A structure where spores are produced.
The medium in which one or more solutes are dissolved.
Solvent
What are Rhizoids?
Root-like structures emerging from the epidermal cells of Bryophytes
Stomata
Regulates gas exchange between plants and enviorment. also controls water loss by contracting
What is it called when gamete’s fuse?
Syngomy
Mycorrhiza (Mycorezay)
A symbolic association between plant roots and fungi
megaspores
usually developed in female gametes
Fungi
Any group of spore-producing organism feeding an organic matter.
Types of Symmetry?
Radial and Bilateral
What are 3 germ layers called?
Triploblastic
What is Triploblastic?
3 germ layer
Ectoderm
Outter Layer, body covering and nervous system
Mesoderm
Middle Layer; Skeloton and Muscles
Endoderm
Inner Layer; Digestive organs and Intestines
What make Bryophytes different from other land plants?
They lack Xylem (vessel that transport water)
What are tracheophytes?
More advanced land plants, they have both xylem and phlem.
What are the two types of green algae?
Chlorophytes-( green plants) They never made it to land
Charophytes- very similar to land plants, both are called Sterptohytes.
What do you know about Coniferophyta aka “Conifers”?
-The are most similar to gymnosperms.
-Usually found in cold temps and dryer regions.
-examples: Pines, firs, spurces.
Double Fertilization
Only happens in angiosperms.
-Happens when female gametes combine with 2 male gametes.
The process of plants sprouting from seed to plants.
