Study Notes

Plant Tissue

Plant growth occurs only in specific regions known as meristematic tissue.
Meristematic tissue is responsible for cell division and growth.
There are three types of meristematic tissue: apical, lateral, and intercalary.
Apical meristem is found at the tips of stems and roots, increasing the length of the plant.
Lateral meristem is found in the vascular cambium and cork cambium, increasing the width of the plant.
Intercalary meristem is found at the base of leaves and internodes, increasing the length of internodes.
Permanent tissues are formed from meristematic tissue when cells lose their ability to divide.
Permanent tissues are classified based on cell structure and function: parenchyma, collenchyma, sclerenchyma, and complex permanent tissue.
Parenchyma tissue is living, loosely packed cells with thin walls and large intercellular spaces. It provides support and storage, and can carry out photosynthesis (chloroplasts) or aeration (aerenchyma).
Collenchyma tissue is living, elongated cells with thickened cell walls, mainly made of cellulose and pectin. They provide mechanical support and flexibility to stems and leaves.
Sclerenchyma tissue is composed of long, dead cells with thick, lignified cell walls. They provide strength and support to the plant body.
Complex permanent tissue includes xylem and phloem, which are responsible for transporting water, minerals, and nutrients throughout the plant.
Xylem transports water and minerals unidirectionally from roots to leaves. It consists of tracheids, vessels, fibers, and xylem parenchyma.
Phloem transports food and other soluble substances bidirectionally throughout the plant. It consists of sieve tubes, sieve cells, companion cells, phloem fibers, and phloem parenchyma.
Epidermis is the outermost protective layer of the plant body, preventing water loss, injury, and pathogen invasion.
Epidermis is covered with a waxy layer called cuticle.
Stomata are small pores on the epidermis that facilitate gas exchange.
Cork is a protective layer that replaces the epidermis in older stems and roots.

Animal Tissue

Animal tissues are specialized groups of cells that perform specific functions. There are four major types: epithelial, connective, muscular, and nervous.
Epithelial tissue forms linings and coverings of internal and external surfaces.
Blood is a connective tissue with plasma, red blood cells, white blood cells, and platelets. It transports oxygen, nutrients, carbon dioxide, waste products, hormones, and cells throughout the body.
Connective tissue provides support, binds together tissues, and protects organs.
Bone is a type of connective tissue that provides support, protection, and aids in movement, with a matrix composed of calcium, phosphorus, and other compounds.
Ligaments are strong connective tissues that connect bones to each other providing strength and flexibility.
Tendons connect muscles to bones, allowing for muscle movement.
Cartilage is a type of connective tissue found in joints, ears, and nose, providing cushioning and support.
Areolar connective tissue is found beneath the skin and around organs, providing support and cushioning.
Adipose tissue stores fat and functions as insulation for the body.
Muscular tissue is responsible for movement, with three major types: skeletal, smooth, and cardiac.
Skeletal muscle is voluntary, striated, elongated, cylindrical, and multinucleated. It attaches to bones and allows for voluntary movement.
Smooth muscle is involuntary, unstriated, spindle-shaped, and uninucleated. It is found in the walls of blood vessels, digestive tract, and other internal organs.
Cardiac muscle is involuntary, striated, branched, and uninucleated. It is found only in the heart and responsible for pumping blood.
Nervous tissue is responsible for communication and coordination, composed of neurons.
Neurons consist of a cell body, dendrites, and an axon. They transmit nerve impulses from one part of the body to another.
