IGCSE UNIT 1
IGCSE UNIT 1 BIOLOGY EXAM GRADED A+
The Characteristics of Life - correct answer Movement, Respiration,
Sensitivity, Growth, Reproduction, Excretion, Nutrition.
Movement - correct answer Changing the individual parts of the
organism or the whole of the organism in response to stimuli
from the environment.
Respiration - correct answer The breakdown of organic molecules in
a series of chemical reactions within a living cell, to produce
energy.
Sensitivity - correct answer The ability to detect changes (or stimuli)
from the environment and respond to them.
, IGCSE UNIT 1
Growth - correct answer A permanent increase in size brought
about by an increase in the individual number of cells or an
increase in the size of cells.
Reproduction - correct answer The production of offspring with one
or more parents through asexual or sexual reproduction.
Excretion - correct answer The removal of wastes of metabolism,
some of which would become toxic if left to accumulate.
Nutrition - correct answer Taking in substances containing atoms or
molecules which can be used to build new molecules that make
up the structure of the organism, produce energy, or have a
metabolic purpose.
What organelles and components are found in a typical animal
cell? - correct answer Nucleus, cell membrane, cytoplasm,
ribosome, mitochondrion, small temporary vacuoles, glycogen.
What organelles and components are found in a typical plant
cell? - correct answer Nucleus, cell membrane, cell wall, cytoplasm,
ribosome, mitochondrion, chloroplasts, small temporary
vacuoles, large permanent vacuole, starch granules.
