Autotrophic Plant:
- Definition: Autotrophic plants are organisms that are capable of producing their own food using energy from the sun through the process of photosynthesis.
- Example: One example of an autotrophic plant is a sunflower.

Photosynthesis in Sunflowers:
Sunflowers are autotrophic plants that undergo photosynthesis to produce their own food. The process of photosynthesis occurs in the leaves of the sunflower plant.

Process of Photosynthesis:
1. Light Absorption: Sunlight is absorbed by the chlorophyll pigment present in the chloroplasts of the sunflower's leaves.
2. Conversion of Light Energy: The absorbed sunlight is converted into chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).
3. Water Uptake: The sunflower plant takes up water from the soil through its roots.
4. Splitting of Water: Water molecules are split into hydrogen and oxygen atoms through a process called photolysis. The oxygen is released into the atmosphere as a byproduct.
5. CO2 Uptake: Carbon dioxide is obtained by the sunflower plant from the air through small openings called stomata present on the leaves.
6. Carbon Fixation: The carbon dioxide combines with the hydrogen atoms derived from the water to form glucose molecules through a series of enzymatic reactions.
7. Glucose Production: Glucose is the primary product of photosynthesis and serves as the main source of energy for the sunflower plant.
8. Storage and Utilization: The glucose molecules produced during photosynthesis are stored in various parts of the sunflower plant and utilized as an energy source for growth, reproduction, and other metabolic processes.

Heterotrophic Plant:
- Definition: Heterotrophic plants are organisms that cannot produce their own food and rely on consuming other organisms or organic matter for nutrition.
- Example: One example of a heterotrophic plant is the Venus flytrap.

Nutrition in Venus Flytrap:
The Venus flytrap is a heterotrophic plant that captures and consumes insects for its nutrition. It has specialized leaves modified into traps to capture its prey.

Process of Capturing Prey:
1. Trap Structure: The Venus flytrap has modified leaves that form a trap structure. Each trap consists of two halves, hinged together, and lined with sensitive trigger hairs.
2. Trap Activation: When an insect or other small organism comes into contact with the trigger hairs, the trap is activated.
3. Rapid Closure: The trap closes rapidly, trapping the prey inside. This is a result of changes in turgor pressure within the cells of the trap.
4. Digestive Enzymes: Once the prey is trapped, the Venus flytrap secretes digestive enzymes into the closed trap.
5. Enzymatic Breakdown: The digestive enzymes break down the prey's proteins, fats,

Autotrophic - All plants expect ( Insectivores plants ) e.g. Neem ,Mango etc..
Heterotrophic -Insectivores plants (e.g. Venus fly trap , Pitcher plant ) .
