ATI TEAS 7 Anatomy and Physiology

ATI TEAS 7 Anatomy and Physiology Ribosomes Involved in synthesizing proteins from amino acids. -Make up about a quarter of a cell. -Some are embedded in the Rough Endoplasmic Reticulum (Rough ER) Golgi Apparatus Involved in synthesizing materials like proteins that are transported out of the cell. ~Modifies and Packages proteins secreted from the cell. -Located near the nucleus and has layers of membranes. Vacuoles Sacs used for storage, digestion, and waste removal. -Plant: Has one large vacuole -Animal: Has small, sometimes numerous vacuoles. Vesicles Small organelle within a cell, has a membrane. -Functions: Moving materials within a cell. Lowest Hierarchy level is at Organelles within a cell. They obtain energy from food and reproduction. -Cells with the same function are collected into larger groups called Tissues. -Tissues are collected into Organs, carry out single task, like oxygenated blood (lungs), or filter out waste (kidneys). -Organs work together in systems that perform coordinated large-scale functions, like nourishing the body (digestive) or protecting the body from attacks (immune). Cell Parts Organelles: Cell parts that function within a cell. They coordinate with other organelles to performs a cell's basic function, like energy processing and waste excretion. ~Examples: Ribosomes, Golgi Apparatus, Mitochondria, The Nucleus. The Nucleus -Nucleus: Small structure that contains Chromosomes and Regulates the DNA of a cell. Defining structure of eukaryotic cells. It is responsible for the passing on of genetic traits between generations. -Contains: nuclear envelope, nucleoplasm, a nucleolus, nuclear pores, chromatin, and
