Biology Chapter on Tissues and Cells

Plant tissue that transports sugars and other nutrients from leaves to other parts of the plant.

Cells in phloem that are responsible for transporting sugars. They have perforated walls and lack nuclei.

Cells in phloem that provide energy to sieve tubes, enabling them to perform their function.

A type of animal tissue that covers and protects exposed surfaces and lines internal cavities.

A type of animal tissue that connects and supports other tissues in the body.

A group of similar cells that work together to perform a specific function. It also includes an extracellular secretion, which is a material produced by cells that helps them function.

Plant tissue with round-shaped cells, loosely packed walls, and an ability to photosynthesize and store nutrients. It's the most abundant type of plant tissue.

Plant tissue with thick, uneven walls. Provides structural support for growing plants, especially young stems.

Plant tissue with thick, rigid walls made of lignin, a strong substance. Provides support and protection to mature plants.

Cells within a tissue are similar in their: shape, structure, and function.

Simple squamous epithelium is a single layer of tightly packed, flat cells. These cells are thin, which makes them great for diffusion and filtration.

Simple cuboidal epithelium is a single layer of cube-shaped cells. They are good at secretion and absorption.

Simple columnar epithelium is a single layer of tall, column-shaped cells. These cells specialize in protection, secretion, and absorption.

Glandular epithelial tissue is a specialized type of epithelial tissue that produces and secretes substances, like sweat, stomach acid, mucus, or hormones.

A single layer of tall, column-shaped cells with cilia on the surface, found in the uterine tube.

A single layer of columnar cells with cilia, but the nuclei are at different levels, giving a stratified appearance, found in the respiratory tract.

The outermost layer of skin composed of multiple layers of flattened, dead cells, filled with keratin, for protection.

Multiple layers of living cells, with the outer layer moist and not containing keratin, found in the lining of the mouth, nose, vagina and anus.

Two or more layers of cube-shaped cells, found in the lining of large ducts, such as sweat glands, salivary glands and pancreas, providing strength.

Multiple layers of columnar cells where the outer layer is responsible for secretion, found in the respiratory tract and mammary glands.

Glands that maintain contact with the body's surface through a duct, releasing secretions like sweat, saliva, or digestive enzymes.

A type of connective tissue that is strong, flexible, and able to resist strain and absorb shock. It's found in many areas of the body, including the nose, trachea, and between vertebrae.

A type of cartilage that is strong and resists compression, found in the nose and trachea.

A type of cartilage that acts as a shock absorber, found between vertebrae.

A type of cartilage that provides a high degree of flexibility, found in the ears, pharynx, and epiglottis.

A type of connective tissue that provides support and protection for the body. Its matrix is solid and calcified, making it strong and rigid.

The primary component of muscle tissue, responsible for contraction and relaxation, allowing movement.

A type of muscle tissue that is responsible for voluntary movements, like walking and lifting weights. It is also responsible for moving the skeleton.

A type of muscle tissue that controls involuntary movements, like digestion and blood circulation. It is found in the walls of hollow internal organs.

A type of muscle tissue that is found only in the heart and is responsible for pumping blood throughout the body. It is involuntary and contracts rhythmically.

Specialized cells that transmit electrical impulses throughout the body, allowing communication and coordination within the nervous system.

A protein found in blood plasma. It helps to maintain osmotic pressure and acts as a carrier protein for various substances.

A type of protein found in blood plasma. They play an important role in immunity by transporting various substances and serving as antibodies.

A protein in blood plasma that is essential for blood clotting. It is activated during injury to help form a fibrin clot.

Dissolved minerals found in blood plasma. These are important for maintaining fluid balance, nerve function, and muscle contraction.

The immune system's response to infection in which the body mounts a rapid but non-specific defense.

The immune system's highly specific response to infection, targeting specific pathogens. It involves memory and adaptation.

A type of white blood cell that engulfs and destroys pathogens by phagocytosis.

A type of white blood cell that contains granules in their cytoplasm. These granules are released during inflammation and immune responses.

A type of white blood cell that presents antigens to T-cells. They play a key role in initiating the adaptive immune response.

A diverse group of proteins that circulate in blood and help destroy pathogens by forming a membrane attack complex.
