Plants Flashcards
(Vascular Plant) Function of the root system:
Penetrates the soil, absorbs water & minerals, & anchors the plant
(Vascular Plant) The shoot system consists of:
The stems, leaves, & flowers
(Vascular Plant) What is the function of the stem:
Serves as the structure for the positioning of the leaves & is the principle site for photosynthesis.
What 3 organs do vascular plants have to carry out their functions:
Roots, stems, & leaves *each of these organs has specialised tissue for their own particular function, but they all contain vascular tissue that forms an interconnected network.
What are the 2 main types of tissue found in the vascular network?
Xylem & Phloem
What does the xylem tissue do?
It carries water throughout the entire plant
What does the phloem tissue do?
It carries water & sugars
What are the 2 types of vascular plants?
Angiosperms (monocots & dicots) & Gymnosperms
What is the name for flowering plants?
Angiosperms
What do angiosperms produce?
Rice, wheat, corn, fibres, wood, drugs, & other products of great value
What are the 2 classifications for angiosperms?
Monocot & Dicot
What is a cotyledon?
Its part of the embryo with in the seed of a plant that contains stored food & serves as a food reservoir.
What do monocots consist of?
- A single cotyledon
- A long narrow leaf
- Parallel veins
- Vascular bundles scattered
- Floral parts in multiples of 3
What do dicots consist of?
- 2 cotyledon
- Broad leaf
- Network of veins
- Vascular bundles in a ring
- Floral parts in multiples of of 4 or 5
What are the 2 main types of root systems?
The taproot & fibrous root
Taproot system
When the primary root enlarges to become the major root
How does the taproot system work?
It reaches deep into the soil for water & anchors the plant firmly in the ground
Give 2 examples of plants of flowers that have a taproot system.
Oaktree & dandelion
Fibrous roots
When the primary root is outgrown by secondary roots
What plants or tress have fibrous roots?
Grasses & maple trees
What characteristics do fibrous roots have?
Fibrous roots have a shallow mass of tangled roots that spread through a large area of soil
