Level of Organization
● Cells:
o Plant Example: Red blood cells
o Animal Example: Root tip cells
● Tissues:
o Plant Example: Dermal – covers and protects
Vascular – transports and supports
Ground – stores and supports
o Animal Example: Muscle – contracts to move body parts
Nerve – carries electrical impulses through the body
Connective – connects body parts
Epithelial covers and lines the inside of body cavities
(hollow parts) for protection
...
o List and describe three benefits of specialization
...
Plant Tissues
● Dermal Tissue:
Function in Root: absorbs water & mineral
protects the plant
Function in Stem: gas exchange: Absorbs carbon dioxide gas (Co2) and releases
oxygen gas (O2)
protects the plant
Function in Leaves: gas exchange: same as above ^
protects the plant
● Ground Tissue:
Function in Root: stores water, minerals, and nutrients
supports the plant
Function in Stem: same ^
Function in Leaves: Production of food (glucose) through photosynthesis
o Vascular Tissue:
Function in Root: transports water, minerals and nutrients
supports the plant
Function in Stem: same ^
Function in Leaves: same ^^
●
Dermal tissue
o
The layer on the outside of the cell
▪
Outermost layer is covered by this tissue
o
Protects the plant
o
Absorbs the water and minerals in the plant
o
Exchange gas
▪
●
CO2 > O2
Ground tissue
o
In the roots of the plant
▪
o
Middle of Vascular and Dermal tissue
Storage for the plant
▪
Water
▪
Minerals
▪
Nutrients
o
Gives the plant support
o
Makes food
▪
●
Glucose through photosynthesis
Vascular tissue
o
Pipes/tubes in the inner core
o
Transports for the plant
▪
▪
Minerals
▪
o
Water
Nutrients
Gives the plant support
Animal Tissues
● Epithelial Tissue: Forms a protective covering on the outside of the body
...
o Example: skin
● Connective Tissue: Unite/connect parts of the body
o Example: fat, tendons, bones, ligaments, cartilage, blood vessel
● Muscle Tissue: Consists of group of cells that are specialized for contraction and
moves body parts
...
The messages sent are all electrical signals
...
o Muscles provide…movement of body parts by pulling on bones
...
The wing opens when the triceps contracts and biceps relax
