TASK2- Nutrition in Plants1° ESO Biology
UNIT 9: PLANT KINGDOM
Plants are autotrophs
● Plants are autotrophs, which means they make their own food.○ They produce organic substances from inorganic substances.
● Nutrition in plants involves multiple processes:1. Absorption of water and mineral salts
2. Transport and distribution of liquids
3. Photosynthesis
4. Cellular respiration
5. Gas exchange
Card A
Absorption
● Water and mineral salts are taken in from the soil through the roots of the
plant.○ The mixture of water + mineral salts is called raw sap.
Card B
Water
Raw sap = salts + water
Water
Raw sap = salts + water
Transport of liquids
● Raw sap is the water and minerals absorbed by
the roots. It travels up from the roots the plant
to the leaves.
● Elaborated sap is the food produced by the
plant. It moves down from the leaves to other
parts of the plant.
Card C
Water
Raw sap = salts + waterElaborated sap: food + water
Photosynthesis
● Green plants use the energy from sunlight,
water and carbon dioxide to make their own
organic matter (food).○ This process is called photosynthesis. It takes place
in leaves mainly.
● Photosynthesis takes place in chloroplasts.
These chloroplasts absorb energy from
sunlight.

Cellular Respiration
● This process is performed
by plants and animals to
make energy.
● The process happens in the
mitochondria in plant cells.

RESPIRATION
Gas Exchange
● Gases enter and come out from the plant through stomata.
● The stomatas are holes in the leaves and work like doors that open and
close.
● Oxygen, carbon dioxide, and water vapour come in or come out through
the stomata.
Card F
VOCABULARY ENGLISH= SPANISH
1. Absorption = Absorción
2. Photosynthesis = Fotosíntesis
3. Cellular respiration = Respiración celular
4. Gas exchange = Intercambio de gas
5. Stomata = Estoma
6. Raw sap = Savia bruta
7. Elaborated sap = Savia elaborada
Card G
Correct themistakes in
thesesentences:
a) Plants are heterotrophs. They
produce organic matter from
inorganic matter.
b) Water and mineral salts are
absorbed by the leaf
c) The elaborated sap travels up
the stem to the leaves.
d) Sunlight enters the plant
through the stomata.
