Different form of the same gene
Biomass
Amount of biological material
Carnivore
Meat-eater
Catalyst
Speeds up reactions
Cellulose
The chemical cell walls are made from

A cell that has become specialised for a particular role
Chromosome
A section of DNA
Combustion
The process of burning
Consumer
Something that eats something else
Cytoplasm
Jelly-like substance in cells. Where reactions happen
Decay
To break down into smaller parts
Decomposer
Micro-organisms that break down material into simple molecules
Denature
Protein structure of enzyme broken down so enzyme cannot work
Detritus
Waste material
Diabetes
A condition where your blood glucose level is hard to maintain
Diffusion
When particles move from a high to a low concentration
Digestion
The breaking down of food into smaller soluble molecules
Dominant
Characteristic that shows up in offspring even if 1 allele is present
Emulsify
Break down large droplets (e.g. fats and oils) into smaller ones
Enzyme
Biological catalysts
Epidermis
The top and bottom layer on leaves
Fertilisation
When a male and female gamete join
Gene
The unit of inheritance (part of a chromosome)
Glucagon
Hormone that converts glycogen to glucose in the Liver
Glycogen
Carbohydrate store
Herbivore
Only eats plants
Homeostasis
The balance of internal conditions
Inheritance
How we get some features from our parents
Insoluble
Does not dissolve
Insulin
Hormone that controls the removal of glucose from your blood
Iodine
used to test for Starch (goes blue/black if starch is there)
Limiting Factor
A factor that will prevent the rate of photosynthesis being the highest possible
Lipids
Fats and OIls
Magnesium
Needed by plants to make chlorophyll
Meiosis
2 stage Sexual cell division. Forms 4 daughter cells with half number of chromosomes
Mendel
Performed experiments with Peas. Came up with the idea of dominant and recessive
Mitochondria
The site of aerobic respiration (energy released)
Mitosis
Asexual cell division forming 2 identical daughter cells
Nitrates
Needed by plants to make proteins
Osmosis
Movement of WATER from a high to a low concentration across a partially permeable membrane
Palisade Cell
Long thin cell in Leaves - contain chloroplasts
Pancreas
Organ that releases 2 hormones, Glucagon and Insulin, Glucagon and Insulin
Phloem
Living ‘Tubes’ that transport sugars around the plant
Photosynthesis
Process that converts light energy, CO2, and water into Glucose and Oxygen
Producer
A green plant
Pyramid of biomass
Shows how the amount of biological material decreases as you move up a food chain
Recessive
Characteristic only shows up in offspring if BOTH alleles are present
Respiration
Process that uses glucose and oxygen to form CO2, Water and releases energy
Ribosome
Where proteins are made in cells
Soluble
Will dissolve
Starch
Plants store glucose in this form
Stem Cell
A cell that has not become specialised
Stomata
the ‘holes’ or ‘valves’ in leaves that allow gases to enter and leave
Thermoregulatory Centre
Part of the brain that controls response to changing temperature
Urea
Produced by the Liver due to the breakdown of excess amino acids
Vacuole
Gives cell support. Provides a storage area for plants (e.g Starch)
Xylem
Non-living ‘tubes’ that transport water and dissolved minerals around plants
