Photosynthesis

Twitter: @LilyKotzè

Process whereby plants use CO2, water and light energy in a series of chemical reactions to produce glucose.

Definition: Photosynthesis

Requirements: Sunlight

Requirements: CO2

Requirements: Water

Requirements: Chlorophyll

Product: Glucose

Product: Oxygen

CO2

Gaseous exchangeabsorption and emission of gases. O2

Found mainly on the leaves

Water in soil is absorbed by the root hairs.

Respiration is used for

Propagation of plants.

‚Propagation’ means making more of a plant.

Cell division

Growth

Some of the glucose is converted to cellulose which makes the cell walls.

Extra glucose is stored as starch (insoluble in water) which is a food source for other living organisms.

Green plants are autotrophs.

Autotrhophic plants make their own food.

Plants that cannot make their own food, need to get it by

other means:

Saprophytes are plants that

survive on dead organic

tissue.

Parasites obtain its nutrients

from its host. This hurts the

host.
