2022 ATI TEAS 7- SCIENCE (HUMAN ANATOMY AND PHYSIOLOGY)*(100% verified answers) Hierarchy of Structures Lowest Hierarchy level is at Organelles within a cell. They obtain energy from food and r... eproduction. -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 ribosomes. Chromosomes Highly condensed, threadlike rods of DNA. DNA is genetic material that stores information about the plant or animal. Chromatin Consists of the DNA and Proteins that make up chromosomes. Nucleolus Structure contained within the nucleus, consists of proteins. Small, Round, and does not have a membrane. Involved in protein synthesis, and synthesizes and stores RNA. Nuclear Envelope Encloses the nucleus. Consists of inner and outer membranes made of lipid [Show More]
