Systems
What two types of tissue are plant cells organised into?
Dermal Tissue and Vascular Tissue
What is Dermal Tissue?
Lining of the outside of plants
What is Vascular Tissue responsible for?
Transporting water and nutrients across a plant
What two systems are plant tissues organized into?
- Root system
- Shoot system
What does the root system contain?
Roots
What does the shoot system contain?
Leaves, stems, flowers, and fruit
Are plants multicellular or unicellular?
Multicellular
Are plants complex or simple organisms?
Complex organisms
What do all vascular plants contain?
Vascular Tissue
What is vascular tissue responsible for?
Transporting water and minerals across a plant
Do non-vascular plants require vascular tissue?
No
The 5 types of vascular plant cells
- Parenchyma cells
- Sclerenchyma cells
- Xylem cells
- Phloem cells
- Collenchyma cells
Function of parenchyma cells
Responsible for photosynthesis and other metabolic activity
Function of Sclerenchyma cells
Provide support
Function of Collenchyma cells
Provide support
Function of Xylem cells
Transport water and minerals from roots to leaves of the plant
Function of Phloem cells
Transport sugars and nutrients throughout the plant
Dermal tissue forms a __________________ between the plant and its environment
physical barrier
How does Dermal Tissue help a plant? (3)
- Creates a physical barrier between the plant and its environment
- Reduces water loss
- Reduces physical damage
Where are ground tissues located in a plant?
Interior
5 main organs of plants
- Leaves
- Flowers
- Fruits
- Stems
- Roots
Function of leaves (2)
- Site of gas exchange
- Responsible for photosynthesis
Function of flowers
Aid in reproduction
Function of fruits
Aid in reproduction
Function of stems
- Support leaves
- Support flowers
- Support fruits
- Transport water and nutrients between roots and shoots
Function of roots
Absorption and storage of water and nutrients from soil
The 4 major animal tissue types
- Muscle
- Nerve
- Connective
- Epithelial
Muscle tissue function
Contracts to exert force
Nervous tissue function (2)
- Detects stimuli
- Transmits electronic signals
Connective tissue function
Connects and supports other tissues and organs
Epithelial tissue function
Composes external and internal parts of the body. Assist in protection, secretion, and absorption
Three types of muscle tissue
- Skeletal
- Cardiac
- Smooth
