Vascular Plants Flashcards
What are vascular plants?
The plant you see most commonly in your daily life. Includes: trees, shrubs, flowering plants, ferns & grasses
Why are vascular plants important?
- They are critical to supporting life on earth, including our own.
- They make up nearly all of our food crops, purify the water & air, provide fuel & give us essential materials like wood & fibre.
Root System
Penetrates the soil, absorbs water & minerals, & anchors the plant.
Shoot System
- Consists of the stems, leaves, & flowers
- The stem serves as the structure for the positioning of the leaves - the principle site for photosynthesis
- The places where the leave join the stem is called the node
- The parts of the stem between the node are called the internode
What are the 3 organs that vascular plants have to carry out their functions?
Roots, stems, & leaves
*All of the organs have specialized tissue for their own particular function; but, they all contain vascular tissue that forms an interconnected network
How does the vascular interconnected network work?
The network extends from the leaves to the roots, & transports water & food (glucose) through the plant in a way thats similar to the circulatory system in mammals.
What are the 2 types of tissues in vascular plants?
Xylem (carries water throughout the plant) & Phloem (carries water & sugars)
(they are to plants what veins & arteries are to humans)
What are the 2 types of vascular plants?
Angiosperms (monocots & dicots) & Gymnosperms
- > monocots have 1 cotyledon, w/ seeds that are in 1 piece like corn
- > dicots have 2 cotyledon, w/ seeds that can split in half like peas
Angiosperms (flowering plants)
- Are the dominant group w/in the vascular plant world
- The basic food supply comes from the seeds & fruits of angiosperms (rice, wheat, corn)
- The also produce fibres, wood, drugs, & other products
Who is John Ray?
He discovered that angiosperms come in 2 different forms based on structure of their seeds: monocot & dicot.
Cotyledon
Is part of the embryo w/in the seed of a plant that contains stored food & serves as a food reservoir
