- Bioelements
- Are the units which living things are composed
of
- Primari
bioelements
- carbon
(C)
- oxigen(O)
- hydrogen(N)
- nitrogen(N)
- phosphorus
- sulphur(S)
- Secondary bioelements
- calcium(Ca)
- sodium(Na)
- magnesium(Mg)
- potassium(K)

- iodine(I)
- Biomolecules;
bioelements join
together .
- Organic biomolecules:
- * They are unique to living
things. Its main elements is
carbon (C)
- Carbohydrates
- They provide instant energy for organisms
- glucose,lactose,sucrose
- lipids
- they store energy for future needs
- fats, waxes,cholesterol
- proteins
- form structures such as hair, skin, and muscles
- haemoglobin,collagen,keratin
- nucleic acids
- contain an individual genetic information
- DNA,RNA
- Inorganic biomolecules
- water
- different functions: thermal
regulation and the transport of
substances
- mineral salts
- participate in the formation of
the rigid structures (bones)
- calcium
carbonate,
calcium
phosphate
- CELLS
- Are the functional
and structural
units of all living
things.
- unicellular
and
multicellular
- Cell

- cytoplasm
- nucleid
acid
- Cell
types
- prokaryote
cell
- size:
0.5-10
um
- genetic
material in
cytoplasm
- plasma membrane is
covered by a cell wall
- small
organelles
- eukaryote
cell
- size:
10-150 um
- genetic material
is contained in
the membrana
(nucleus)
- cytoplasm particular
jobs: cellular
organelles
- plant: they have a
cell wall covering
the plasma
membrane.
Contains
choloplasts
- animal: they do
not have a cedll
wall. They do not
have chloroplast
- cell
epecialisation
- division of
labour
- greater
efficiency
- longevity
- VITAL
FUNCTIONS
- Nutrition
- The purpose of
nutrition is to
renew and
help preserve
the
organism´s
structure, as
well as
obtaining
energy to
perform the
three vital
functions
- cellular metabolism
- anabolism
- catabolism
- types
- autotrophic
- heterotrophic
- Interaction
- allows living things to
interact with their
environment, detect any
changes in it and react to
therm
- reproduction
- asexual
- a single individual
creates multiple
descendants which are
identical.
- bipartition
- budding
- sporulation
- sexual
- it requires two individuals of the opposite
sex
- Vital functions in plants
- plant nutrition
- photosynthesis
- water+minerals
salts+CO2+sunlight =
organic matter + O2
- cell respiration
- organic matter + O2
= water + CO2 +
energy
