1
00:00:00,320 --> 00:00:02,640
A sunflower seed looks asleep,

2
00:00:02,640 --> 00:00:04,600
but it holds a tiny plant,

3
00:00:04,600 --> 00:00:07,890
stored food, and a protective coat inside.

4
00:00:10,280 --> 00:00:13,053
Water softens the seed coat. The seed

5
00:00:13,053 --> 00:00:15,120
swells, its cells wake,

6
00:00:15,120 --> 00:00:17,290
and the shell begins to split.

7
00:00:20,240 --> 00:00:22,560
The first root pushes downward,

8
00:00:22,560 --> 00:00:25,000
anchoring the plant and collecting water and

9
00:00:25,000 --> 00:00:26,730
minerals from the soil.

10
00:00:30,280 --> 00:00:33,120
Next, a pale shoot curves upward,

11
00:00:33,120 --> 00:00:35,480
powered by stored food before green leaves

12
00:00:35,480 --> 00:00:37,770
can make energy from sunlight.

13
00:00:40,280 --> 00:00:43,240
Above the soil, two leaves open. In

14
00:00:43,240 --> 00:00:46,360
sunlight, the young plant begins making sugar

15
00:00:46,360 --> 00:00:48,170
through photosynthesis.

16
00:00:50,280 --> 00:00:52,960
Roots spread, the stem strengthens,

17
00:00:52,960 --> 00:00:55,800
and the sunflower turns toward light. One

18
00:00:55,800 --> 00:00:57,880
quiet seed is ready to make many

19
00:00:57,880 --> 00:00:58,730
more.
