8. Comparing Plant & Animal Organs & Tissues

Animal Tissues: ?

Animal Tissues:

• A tissue is a collection of similar cells that perform a particular but limited function.

Epithelial Tissue: ?

Epithelial Tissue:

• Covers the body,

• lines the internal organs and cavities.

Epithelial Tissue:

Multi-layer ?

Examples:?

Epithelial Tissue:

Single Layer

• Thicker tissues prevent body from injury

• Examples: Skin & Mouth

Epithelial Tissue:

• Single Layer?

• Examples: ?

Epithelial Tissue:

Single Layer

• Thinner allowing material to pass

• Examples: Lungs & Heart

Connective Tissue:?

Connective Tissue:

• Supports, connects and protects the body’s organs

Nerve Tissue: - Sensing & Responding

What is a Nerve Cell?

Nerve Tissue: - Sensing & Responding

What is a Nerve Cell?

• A cell that communicates information from all over the body to the brain where it is processed.

There are 3 kinds of nerve cells:

There are 3 kinds of nerve cells:

1. Sensory Nerves:

• Gather information from the bodies senses

2. Motor Neurons:

• Carry information from brain to another body part

3. Interneurons:

• Connect sensory and motor neurons together

(These are nervous system)

Muscle Tissue is Made of ?

Muscle Tissue

• Made of special cells that can contract

There are 3 kinds of muscle cells:?

Examples?

There are 3 kinds of muscle cells:

1. Skeletal muscle:

• Controls voluntary actions

• Examples: Exercise, Walking

2. Smooth Muscle:

• Controls involuntary actions

• Examples: (Breathing, Digestive System)

3. Cardiac Muscle :

• Controls involuntary heart contractions

• Examples: (Heart beating/Maintaining Rhythm)

types of connective tissue ?

are types of connective tissue.

• Blood,

• bones,

• cartilage,

• tendons

• and ligaments

What is an organ?

What is an organ?

• An organ is a number of tissues that work together that perform a specialized function

Brain: ?

Composed of: ?

Brain:

- Receives all sensory information from the body.

- Coordinates our responses / & actions

Composed of:

• Mainly, Nervous tissue

Skin: ?

Composed of: ?

Skin:

- Largest organ in the body.

- Purpose is to protect body from pathogens

- A pathogen is something that causes disease

Composed of:

• Epithelial and Connective tissue

Heart: ?

Composed of: ?

Heart:

- Pumps blood throughout the body

- Circulation is needed for all organs to function because blood carries

nutrients and oxygen needed.

Composed of:

• Muscle, epithelial, nervous tissue

Lungs:

Composed of: ?

Lungs:

- Responsible for gas exchange between blood and air around us.

- Oxygen enters the blood, while carbon dioxide exits the blood

- Alveoli are tiny sacs where the gas exchange occurs.

Composed of:

• epithelial and connective tissue

- A pathogen is ?

A pathogen is

• something that causes disease

- Alveoli are ?

Alveoli are

• tiny sacs where the gas exchange occurs.

Digestive system: ?

Digestive system:

- Esophagus tube

• that leads to your stomach

- Small intestine

• where the nutrients from your food are absorbed into the bloodstream

- Large intestine

• collects and removes waste materials.

Digestive system is omposed of what tissues?

Digestive system is Composed of all four tissue types:

• epithelial,

• connective,

• nervous,

• and muscle

Tissues in Plants

There are 4 types of tissues in plants:

Tissues in Plants

There are 4 types of tissues in plants:

1. Epidermal tissue

2. Vascular tissue

3. Ground tissue

4. Meristematic tissue

Epiderma Tissue: ?

• Clear and very thin. “ _____ ” are ‘guard cells’ that do what?

Epiderma Tissue:

• Found on the top and underside of a leaf.

• Clear and very thin. “ Stomata ” are ‘guard cells’ that allow nutrients to move in and out of the leaf.

Vascular tissue: ?

Vascular tissue:

• Transports water and nutrients through the plant.

Ground tissue: ?

Roots?

leaves?

Ground tissue:

• Most of the plant. Stem provides strength and support.

Roots

• Food and water storage

Leaves

• Photosynthesis occurs

Meristematic Cells:

Meristematic Cells:

• These are like stem cells for plants.

• Responsible for growing new parts of a plant.

• Found on the tips of plant roots

Type of vascular tissue is either: ?

Type of vascular tissue is either:

Xylem

• Moves water and nutrients from root to leaves (one way)

Phloem

• Transports sugar (water, sucrose, and amino acids) from leaves to other parts of the plant (two way)

Plant Organs

Roots Function: ?

Composed of: ?

Plant Organs

Roots Function:
