cells

Peroxisomes

small vesicles in cytoplasm that detoxify toxic substances; for example, they may contain enzymes that degrade hydrogen peroxide and fatty acids

Golgi apparatus

one or more flattened stacks of membranes that modify and package proteins and lipids for intracellular or extracellular use

Plasma membrane

The cell membrane function to protect, secret, and uptake substances

Lysosomes

Vesicles containing digestive enzymes

Endoplasmic reticulum

Membranous network in the cytoplasm, studded with ribosomes for protein synthesis or laking ribosomes and involved with lipids and steroid synthesis

Centrioles

Paired bundle-like inclusions essential for chromosomes movement in cell division

Ribosomes

Tiny particles in cytoplasm containing RNA and proteins both free and attached to rough ER. are involved in protein synthesis by translating the amino acid protein coding under the direction of messeger RNA (mRNA)

Microfilaments

Fine filaments of actin, the contractile protein, that provide strength, support and/or intracellular movement, and are involved in muscle contraction

Microtubules

Tubulin protein inclusions that support the cell and assist in intracellular transport

Epithelial Tissues

covers body surfaces, lines cavities ducts of organs and glands and forms the secretory portion of glands. Participates in absorption and secretion

Squamous Epithelial tissue

Thin, flattened cells; the width of each cell is greater than its height
