1.3 Information Flashcards
Epithelial tissue
Made of cells that are tightly packed together to form a protective barrier
Can be one cell thick or be many layers of cells
Epithelial tissue major function
Lines body cavities and outer surface of the body
Protects structures
Forms glands that produce hormones enzymes and sweat
Connective tissue function
Main function is to join other tissue together Supports and protects structures Forms blood Stores fat Fills empty space
Types of connective tissue
Tendons Ligaments Bones Cartilage Blood
Tendons
Connect muscles to bones
Ligaments
Connect bones to bones
Blood components
Plasma
Red blood cell
Red blood cell
Platelet
Plasma
Made of water proteins and dissolve nutrients and water such as CO 2
Most of blood by volume 50 percent
Red blood cell
Have dimple to increase SA
Contains hemoglobin a protein that can absorb and release oxygen
40 percent of blood
White blood cell
Larger in size
Protects the body from bacteria and viruses and fights infections
Platelets
Cells that help in the process of blood clotting
Smallest of the 3
Types of muscle tissue
Smooth
Skeletal
Allow for movement
Cardiac
Skeletal muscle
When moving arm or leg
Voluntary
Smooth muscle
Blood vessels
Stomach
Other muscles
Involuntary
Cardiac muscle
Only found in heart involuntary
Nervous tissue
Made of nerve cells
Create messages called impulses and transmit them throughout the body
Receive info from inside and outside the body
Responds to stimuli and transmits and stores information
Types of plant tissues
Epidermal Vascular Ground Meristematic All are formed from groups of meristematic cells known as meristematic tissue
Meristematic tissue function
Unspecialized tissue capable of dividing by mitosis
Found in several locations of the plant
Responsible for growing new parts of the plant
Epidermal tissue
Is that in on top and underside of the leaf
Form a tiny opening by guard cells called stomate
Found on underside of leaf
Epidermal tissue function.
Forms protective outer covering
Allows for the exchange of materials and gas in and out of the plant
Ground tissue
Most of the plant is made of it
Ground tissue function
Roots stores food and water
Stem provides strength and support
Leaves photosynthesis in specialized ground tissue called mesophyll o
Vascular tissue
Transports water and nutrients throughout plant
Xylem
Vascular tissue that moves water and minerals from roots to stem and leaves
