BOTANY LAB: TISSUES Flashcards
A group of closely associated cells that perform related functions and are similar in structure
TISSUES
Organized into three tissue systems: Dermal tissue system, Ground tissue system, and the Vascular tissue system
PLANT TISSUE SYSTEMS
► Plants are Earth’s Primary Producers
► Harvest Energy from sunlight by converting light energy into
chemical energy
► They store this chemical energy in bonds formed when they synthesize carbohydrates from carbon dioxide and water.
► Non-motile
► Have evolved to grow towards resources throughout their life span.
PLANT STRUCTURE
PLANT STRUCTURE
Vegetative body
- Photosynthesis
LEAF
PLANT STRUCTURE
Vegetative body
- Support
STEM
PLANT STRUCTURE
Vegetative body
- Anchorage and absorption of water and minerals
ROOTS
PLANT STRUCTURE
Vegetative body
- Leaf attached to stem
NODES
PLANT STRUCTURE
Vegetative body
- Region of stem between two nodes
INTERNODE
SHOOT AND ROOT SYSTEMS
- Produces sugars by photosynthesis
- Carries out reproduction
SHOOT SYSTEM
SHOOT AND ROOT SYSTEMS
- Anchors the plant
- Penetrates the soil and absorbs water and minerals
- Stores food
ROOT SYSTEM
PLANT TISSUE SYSTEM
GROUND TISSUE SYSTEM
VASCULAR TISSUE SYSTEM
DERMAL TISSUE SYSTEM
PLANT TISSUE SYSTEM
- Protection, Prevention of water loss
- Epidermis, Periderm (in older stems and roots)
DERMAL TISSUE SYSTEM
PLANT TISSUE SYSTEM
- Photosynthesis, Food storage, Regeneration, Support, Protection
- Parenchyma, Collenchyma, Sclerenchyma
GROUND TISSUE SYSTEM
PLANT TISSUE SYSTEM
- Transport of water and minerals, Transport of food
- Vascular bundles (xylem and phloem)
VASCULAR TISSUE SYSTEM
PLANT TISSUE SYSTEM
- it protects the soft tissues of plants and controls interactions with the plants’ surroundings
