Levels of Biological Organization

Epithelial Tissue

Tissue that covers surfaces and lines body cavities and organs.

Functions include: Protection, Absorption, Sensation, Secretion

Connective Tissue

Tissue that supports, connects, binds, and protects different parts of the body.

Examples include: Bone, Blood, Adipose tissue, Cartilage

Muscle Tissue

Tissue specialized for contraction and movement.

Skeletal Muscle

TYPES OF MUSCLE TISSUES:

• Voluntary

• Attached to bones

• Helps produce body movement

Smooth Muscle

TYPES OF MUSCLE TISSUES:

• Involuntary

• Found in walls of internal organs

Cardiac Muscle

TYPES OF MUSCLE TISSUES:

• Involuntary

• Found in the heart

Nervous Tissue

Tissue specialized for receiving and transmitting signals.

Skeletal, Smooth, Cardiac

ENUMERATE THE TYPES OF MUSCLE TISSUES

Red Blood Cell

Xylem

Vascular tissue that transports water and minerals from the roots toward the leaves.

Phloem

Vascular tissue that transports sugars/food produced by photosynthesis to other parts of the plant.

Epidermis

The outer protective tissue of non-woody plants.

Peridermis

Protective dermal tissue that develops in woody plants as they undergo secondary growth.

Stomata

Small openings, usually found on plant leaves, that regulate gas exchange.

They allow gases such as carbon dioxide and oxygen to move into and out of the plant.

Root Hair Cell

A specialized plant cell with a long, thin extension that increases surface area for absorbing water and minerals from the soil.
