1. Plant Structure

2. Plant Structure
The raw materials of photosynthesis enter the plant through different structures.
Sunlight is absorbed by the chlorophyll in the chloroplasts within the leaves.

3. Plant Structure Carbon dioxide enters the leaves through the
Stomates (stomata) which are controlled by guard
cells.
Water can be lost by transpiration through the
stomata.
The cuticle ( waxy outer covering) minimizes
water loss.

4. Water and minerals enter the plant through the xylem.
Plant Structure
Water and minerals enter the plant
through the xylem.
The products of photosynthesis are
transported throughout the plant by the
phloem.

5. Chloroplasts
Photosynthesis takes place inside organelles called chloroplasts.

6. Chloroplasts
Chloroplasts contain saclike photosynthetic membranes called thylakoids, which are interconnected and arranged in stacks known as grana.

7. Chloroplasts
Pigments are located in the thylakoid membranes.

8. Chloroplasts
The fluid portion outside of the thylakoids is known as the stroma.
