Cards

Term
Biology
Definition
Science that deals with all forms of life.
Term
Botany
Definition
Study of Plants
Term

Different types of Botany fields include?

P G.A.M.E.S.

Definition

Plant anatomy—Cell and tissue structure
Plant ecology—Role of plants in the environment
Plant genetics—Genetic inheritance in plants
Plant morphology—Structure and life cycles
Plant physiology—Life functions of plants
Plant systematics—Classification and naming of plants
Term
What are the two types of Botany Technology?
Definition
Conservation and Bio Technology
Term
Conservation Technology
Definition
A multidisciplinary field of science that studies the impact of human activities on all faccets of the environment
Term
Biotechnology
Definition

Efforts to obtain improved plants and plant products using scientific techniques.

 

Ex. sheese, wine, beer, vaccines, insulin.

Term
Herbals/Doctrine of Signatures
Definition
The Doctrine of Signatures is an old tradition, or a part of many traditions, that plants (as well as animals and minerals and perhaps even phenomena) have clues or *signatures* in their shapes and forms and actions and things that tell what their purposes are.
Term

Characteristics of Living Organisms

G.  C.H.H.A.R.R.M

Definition
  1. Growth and Development
  2. Cellular Structure
  3. Homeostasis-maintain stable as a whole
  4. Heredatary Material- RNA,DNA,Genetic Material,Blueprint
  5. Ability to Evolve
  6. Reproduce
  7. Respond to Stimuli
  8. Metabolism-Converge Energy
Term
Cellular Respiration
Definition
Bodily process whereby oxygen in the blood is absorbed by the cells of the body and carbon dioxide is absorbed by the blood as a waste product to be transported to the lungs.
Term
Cell Theory
Definition
Cells are the basic unit of structure in every living thing.
Term
Prokaryote
Definition
bacteria and cyanobacteria: A simple organism without a nucleus: an organism whose DNA is not contained within a nucleus.
Term
Eukaryote
Definition
organism with visible nuclei: any organism with one or more cells that have visible nuclei and organelles.
The group contains all living and fossil cellular organisms except bacteria and cyanobacteria.
Term
Vascular
Definition
  fluid-carrying vessels: relating to fluid-carrying vessels, e.g. blood vessels in animals or the sap-carrying vessels in plants


Term

Characteristics of a Plant

M.A.C.E

Definition
  1. Multicellular Eukaryote
  2. 2 Adult Forms-Alteration of generationsCapable of Photosynthesis
  3. Cell Walls-made of cellulose
  4. Capable of photosynthesis
  5. Embryo protected w/ in mother plant
Term

What are the 4 major groups of plants?

B.A.G.S.

Definition
  1. Bryophytes-simplest forms (moses)
  2. Seedless Vascular-Simplest cascular plants
  3. Gymno Sperms-non flowering seed plants (pine tree,conifers)
  4. Anglo Sperms-Flowering seed plants, seeds wrapped in protection
Term
Bryophytes
Definition
  nonflowering simple plant: a nonflowering plant, often growing in damp places, that has separate gamete-bearing and spore-bearing forms, e.g. moss.


Term
Seedless Vascular
Definition
They are "seedless" because they reproduce by means of spores
Term
Gymnosperms
Definition

  woody cone-bearing plant: a woody vascular plant in which the ovules are carried naked on the scales of a cone, e.g. a conifer, cycad, or ginkgo. See also angiosperm


Term
Angiosperms
Definition
  flowering plant: a plant in which the sex organs are within flowers and the seeds are in a fruit. See also gymnosperm
Term
Interderminate Growth
Definition
Indeterminate growth refers to growth that is not terminated in contrast to determinate growth that stops once a genetically pre-determined structure has completely formed.
Term
Mitosis
Definition
Cell division in which the nucleus divides into nuclei
  containing the same number of chromosomes
Term
Meiosis
Definition
Process of cell division: in organisms that reproduce sexually, a process of cell division during which the nucleus divides into four nuclei, each of which contains half the usual number of chromosomes.


Term
Explain a plants role in the carbon and nitrogen cycle?
Definition

Through cellular respiration and cellular break down Carbon Dioxide is released into the air which plants then convert into Oxygen.

 

In assimilation plants take the nitrogen from the soil and incorporate the nitrogen into amino acids, nucleotides and other organic compounds which the consumers eat.

Term
  1. What adaptions do plants make for the cold?
  2. Why are northern forests like deserts?
  3. How extensive is the coniferous forest?
  4. How do animals adapt for survival in cold areas?
  5. What is the importance of fires in some areas?
  6. Give examples of interdependence in organisms?
Definition
  1. They go dormant, only sending nutrients to vital systems. Deciduate,Branches face down.
  2. So cold, moisture freezes so its like there is no water.
  3. Around the Globe
  4. Store food, hibernate, move around to stay warm
  5. Reproduce nutrients into the soil.
  6. All animals have respect for eachother without greed.
Term
Photosynthesis
Definition
The process by which plants use solar energy  to make their own food, transforming carbon dioxide and water into sugars that store chemical energy.
Term
Food chain
Definition
A sequence of food transfer from one organism to the next, beginning with a food producers.
Term
Primary producers
Definition
Organisms that make their own food, such as plants and other photosynthetic organisms.
Term
genes
Definition
A specific sequence of DNA nucleotides coding for one protein
Term
Genetic Engineering
Definition
The process of moving and modifying genes to produce plants with desired traits.
Term
Nucleus
Definition
A membrane bound structure that contains the cells, DNA
Term
Autotrophs
Definition
Self feeder, A plant that can make its own food through photosynthesis.
Term
Heterotrophs
Definition
Other Feeder, An organism, such as an animal, that obtains food from other organisms.
Term
Spores
Definition
A reproductive cell of plants that can develop into an adult without fusing with another reproductive cell.
Term
Sexual VS Asexual Reproduction
Definition
A sexual is where a single parent produces offspring that are identical compared to 2 parents with an egg and a sperm with combined characteristics.
Term
Vascular tissue
Definition
Plant cells joined into tubes that transport water and nutrients throughout a vascular plant's body.
Term
Seed
Definition
A structure that includes a plant embryo and a store of food, packaged together within a protective coat.
Term
Deductive VS Inductive reasoning
Definition
Induction is usually described as moving from the specific to the general, while deduction begins with the general and ends with the specific;
Term
Hypothesis VS Theory
Definition

A theory is a well-established principle that has been developed to explain some aspect of the natural word.

 

A hypothesis is a specific, testable prediction about what you expect to happen in your study

Term

How are plants directly or indireclty the source of most the world's energy?

Definition
Photosynthesis supports all life on earth by producing oxygen, produce sugars and other molecules, which are the building blocks of life, provide energy directly to plants and tehrefore indirectly to other organisms in food chains.
Term
Explain how Photosynthesis makes life on Earth possible?
Definition
Photosynthesis supports all life on earth by producing oxygen, produce sugars and other molecules, which are the building blocks of life, provide energy directly to plants and tehrefore indirectly to other organisms in food chains.
Term
What are GM plants? What are some of the negatives and the positives of GM plants?
Definition

Genetically modified plants provide sources of nutrients and vaccines  and are resistant to pest, herbacides and toxic soil and minerals.

Some negatives include having anti-biotic resistance which can lead to anti-biotcs not being as effective.
