Life Processes: 5

• What type of nutrition is shown by insectivorous plants?

Venus flytrap → Green → Chlorophyll

it states that venus flytrap is autotrophic because photosynthesis occurs.

→ insects (Heterotrophic) → Carnivorous plant

VENUS FLYTRAP IS PARTIALLY HETEROTROPHIC

• CYNOBACTERIA: also called blue green algae

  the green word in blue green algae states that it has chlorophyll → photosynthesis → CYNOBACTERIA IS AUTOTROPHIC

AUTOTROPHIC NUTRITION IN PLANTS

• photosynthetic autotrophic nutrition

  photosynthesis require

  • CO2
  • H2O
  • Sunlight
  • Chlorophyll

The product of photosynthesis

• Food (Glucose- C6H12O6)
• Oxygen
• Water

1. Does photosynthesis occur in all parts of plants?

   → no it only occurs in green parts of plants.

2. Where does it occur?

   → leaf cells → “chloroplast”

Chlorophyll

→ Green pigment which absorbs light

→ Present in chloroplast

LEAF CELLS → “Mesophyll cells of the leaf”

• The mesophyll cells have chloroplast which does photosynthesis.
