Cell specialization + animal and plant cells, tissues and organs

Unspecialized cells in animals

Stem cells

Unspecialized cells in plants

Meristematic cells

Process where a simple cell develops into a complex cell

Specialization/difrenation

When cells are specialized they have (4)

Specific function

Special shape

Different numbers of organelles

Particular arrangement/connection to other cells

Once the cells are specialized

Cells group together to perform a common task in a tissue

Stem cells specialize into

1 of 4 types of cells

Once specialized

Cells group together to form tissues with the same name as cells

Epithelial cell

thin, flat, and connected to others on all sides

Epithelial tissue

covers and protects the body inside and out

Muscle cell

contains protein which contract and relax

Gal bladder

Stores bile and releases it to help with the digestion of fat

Gall bladder tissues

Epithelial tissue lines the inside

Muscle tissue contracts to release bile

Connective tissue supports and holds the other tissues together

Stomache

Helps digest food by mixing it with acid to turn it into a thin liquid

Tissues in the stomach

Epithelial tissue cover the inside to protect from the acid

Muscle tissue mix food with acid and push it into intestines

Nervous tissue coordinate muscle movement

Connective tissue supports and holds all tissues together

How many main organs in a plant

4

What are the main organs In the plant

Leaf

Flower

Stem

Root

Leaf

Site of most photosynthesis

Tissues in a leaf

Epidermal tissue covers leaf surface

Vascular tissue is bundled in a vein to transport water and nutrients

Ground tissue consists of mesophyll cells that perform most photosynthesis

Root

Anchors the plant and absorbs nutrients

Tissues in root

Epidermal tissues covers the root to prevent damage and helps absorb water and nutrients

Vascular tissues in centre to transport absorbed water and nutrients to rest of the plant

Ground tissue for storage of nutrients

Meristematic tissue at root tip for growth

Muscle tissue

allows for movement

Always present to help grow new plant parts

meristematic cells

Large number of cells grouped together

Meristematic tissue

Meristematic cells specialize into

1 of 3 main types

Meristematic cells

Unspeacia,iced and undergoing cell division

Meristematic tissue

Grows new plant parts

Ground cell

Have a variety of structures and shapes (plant)

Ground tissues

Supports and protects (plant)

Epidermal cell

Thin, flat, connected to others but with some openings

Epidermal tissue

Protective outer covering

Vascular cells

Connect to form long tubes

Vascular tissue

Moves substances between roots and leaves

How many main organs in the human body

78

Nervous cells

Have a branches to connect to other cells

Nervous tissue

Transmits and responds to information

Connective cells

Have a variety of structures and shapes (animal)

Connective tissue

Supports and protects (animal

Growing plants have a

Terminal buds

Flower

To faciliate reproduction by attracting pollinators for the transfer of pollen

Flower tissues

Ground tissue serves as a site for photosynthesis

Vascular tissue helps store water and sugars

dermal tissue covers and protects the plant
