Edexcel IGCSE Biology Definitions
Nutrition - ANS Provide living organisms with energy and raw material for growth and repair.
Respire - ANS Living organisms release energy from their food.
Excretion - ANS The removal of waste products such as carbon dioxide and urine carried out by the skin,
the lungs and the kidneys.
Response - ANS Nerve coordination and reaction to stimuli.
Reproduction - ANS To produce offsprings for their species to survive.
Cells - ANS Tiny building blocks of living organisms.
Multicellular - ANS Organisms that contain a lot of cells and therefore need organisation.
Organelles - ANS Tiny structures within cells.
Nucleus - ANS Contains genetic materials that control the cell's activities.
Cell membrane - ANS Outer surface of the cell and control movement of substances in and out.
Cytoplasm - ANS Place of most chemical reactions and contain enzymes.
Chloroplasts - ANS Contain chlorophyll and carry out photosynthesis.
, Cell wall - ANS Rigid structure made of cellulose that supports and strengthens cells.
Vacuole - ANS Large organelle that contains cell sap.
Cell sap - ANS A weak solution of sugars and salts.
Tissue - ANS A group of similar cells that work together to carry out particular function.
Xylem tissue - ANS For transporting water and mineral salts in plants.
Phloem tissue - ANS For transporting sucrose and amino acids in plants.
Organ - ANS A group of different tissues that work together to perform a function.
Organ system - ANS A group of orgANS that does a particular job.
Cereals - ANS Example: maize
Herbaceous legumes - ANS Example: beANS and peas
Mycelium - ANS A structure of fungi.
Hyphae - ANS Thread like structure that make up mycelium.
