Botany The study of plants
A botanist is a person who studies plants.
The process of seed beginning to grow is called germination. Watch this video about germination.

The outer covering of a seed is the seed coat.
The embryo is the inside of a seed that is the beginning of a new plant.
The cotyledons are the halves of the seed that provide food for the new bean plant until the plant has green leaves and can make its own food.
The radicle is the beginning of the root system of the plant.
Remember when we disected the bean seed. Here's a video to review what we did. https://www.youtube.com/watch?v=mgSzn-RJ3Zg
Here's a cartoon about germination. https://www.youtube.com/watch?v=oYzXToyEzBU
Vascular plants are plants with roots, stems, and leaves.
Here are some videos on vascular and nonvascular plants. https://www.youtube.com/watch?v=0NWkPHRnqdw

Angiosperms are flowering plants. Gymnosperms are plants with seeds in cones. In angiosperms the seeds are in the fruits, but in gymnosperms the seeds are in the cones.
You can watch this video about angiosperms and gymnosperms. https://www.youtube.com/watch?v=gTQ9gsZBMPI
Parts of a Plant
Watch Dr. Binocs explain the parts of a plant: https://www.youtube.com/watch?v=p3St51F4kE8
The roots absorb water and minerals from the soil and also act as an anchor. When it is windy the roots make sure the plant stays firm in the soil.
The stem holds the plant upright and carries water, food, and minerals to the other parts of the plant.
The leaves have a green pigment called chlorophyll which absorbs the sunlight and makes food for the plant.
In angiosperms, the bud protects the flower as it develops. The flower is usually colorful to attract bees and insects.
The fruit of a plant contains the seeds and excess food.
Remember, in angiosperms the seeds are in the fruits, but in gymnosperms the seeds are in the cones.

Photosynthesis is the process by which plants make their own food.
Sunlight shines on the plant. The chlorophyll are molecules in the chloroplasts in the leaves. The chlorophyll absorb sunlight. The stomata are tiny holes on the under side of leaves that take in carbon dioxide. The plant uses the sunlight, water, and carbon dioxide produce food in the form of sugar, which is called glucose, in the chloroplasts in the leaves. During photosynthesis oxygen is released or given off by the plant. Only green plants can photosynthesize.
In this video Dr. Binocs explains photosynthesis. https://www.youtube.com/watch?v=D1Ymc311XS8
And now my favorite plant songs:
"Photosynthesis" by Peter Weatherall He calls glucose cellulose. https://www.youtube.com/watch?v=wj8TGhcCnxs
Here's another fun song by English Through Music Madridhttps://www.youtube.com/watch?v=Cjp2KaVM_go
This is a song about seeds put to "Me" by Katy Perry., rewritten by Mr. Parr. https://www.youtube.com/watch?v=P6asGePMzxo
This is "How Seeds Move" by Mr. R. https://www.youtube.com/watch?v=3CCOWHa-qfc
The needs of a plant are in this song. https://www.youtube.com/watch?v=dUBIQ1fTRzI
