Ecology
The Conversion of nitrogen gas into ammonia (NH3), ammonium (NH4+) or nitrate ( NO3−)
What is Nitrogen Fixation?
TRhese are Single sugar molecules such as Glucose
What are Monosaccharides
This Is a spontaneous inheritable change in the structure of the genetic material.
What is a Mutation?
These cells have a membrane bound nucleus and organelles.
What are Eukaryotic cells?
This Zone is where active cell division in plants takes place.
What is the meristem?
This Involves all the competing organisms getting some of the resources. Eg – Seedlings competing for space around parent plant.
What is Scramble Competition
The Conversion smaller molecules into larger ones. (Using energy)
What is an anabolic reaction?
This is A mechanism of evolution whereby the best-adapted individuals survive and produce more offspring. Or inheritable change within a population in response to change in the environment by natural selection over time.
What is natural Selection?
Defined as biological catalysts, protein in nature. These speed up the reactions in the cell without being used up in the reaction.
What are Enzymes?
This is the growth response of a plant to an environmental stimulus.
What is tropism?
This is Relationship between 2 organisms of different species that live in close association to the benefit of both organisms
What is Symbiosis
These are Fat-like substances where one of the fatty acids is replaced/added a phosphate group
What are Phospholipids?
Found in the nucleus, made of DNA and protein and contain genes along their length.
What is a Chromosome?
:This enzyme digests protein
What is Protease
The regrowth of the embryo, after a period of dormancy, if the environmental conditions are suitable.
What is germination?
The Aspects of the soil that influence an ecosystem such as the soil pH, soil type, moisture, air and mineral content of soil.
What are Edaphic Factors?
These are Molecules found in living things are composed of atoms where elements bonded together in different ratios to form biomolecules. Such as Carbohydrates, Lipids, Proteins and Vitamins.
What are Biomolecules?
This is the expression of the gene in the environment. This is how genes affect the appearance of the organism.
What is a Phenotype?
The phase in the cell cycle when the cell is not dividing.
What is Interphase?
This is the Loss of water vapour from the leaves and other aerial parts of a plant.
What is Transpiration?
All the member of the same species living in an area.
What is a population?
These are Made up of many sugar molecules bonded together. Eg - Starch, Glycogen and Cellulose
This is When 2 alleles for a particular characteristic are the same. Eg – TT = Tall and tt = short
What is Homozygous?
This form of cell division produces four genetically different daughter cells, each of which has half the number of chromosomes of the parent cell.
What is Meiosis?
These are all the Male parts of the flower
What is the stamen?
