Cell Structure and Functions
the basic units of all living things: Bacteria, plants, and animals—including human beings
What is a cell?
It is a group of similar cells that perform a specific function. There are four types of tissue in the bod
What is tissue?
They are groups of specialized tissues that perform specific functions.
What are Organs?
Coordinates all other body systems, allowing them to work efficiently and react to the environment
What is the Nervous system?
A cell is made up of this, in which nutrients, mineral salts, and water are present
What is protoplasm?
It is fibrous tissue that binds and supports other body tissues and organs.
What is Connective Tissue?
Controls blood movement throughout the body
What is the Circulatory system?
Coordinates all other body systems, allowing them to work efficiently and react to the environment
What is the Reproductive system?
This is the specialized structure in the center of the cell. It controls the growth and reproduction of the cell; it also contains the cell’s genetic material
What is the nucleus?
It provides a covering that protects the body and is found in many parts of the body, such as the skin, mucous membranes, digestive and respiratory organs, the lining of the mouth, the heart, and glands.
What is epithelial tissue?
Breaks food down into nutrients or waste for nutrition or excretion
What is the Digestive system?
Makes blood and oxygen available to body structures through respiration; eliminates carbon dioxide
What is the Respiratory system?
It is the watery fluid that surrounds the nucleus. It provides a structure for the cell parts so that they can move freely within the cell membrane
What is Cytoplasm?
Carries messages to and from the brain and controls and coordinates all bodily functions.
What is nerve tissue?
Controls hormone levels within the body that determine growth, development, reproduction, and health of entire body
What is the Endocrine system?
Forms the physical foundation of the body; composed of 206 bones connected by moveable and immovable joints
What is the Skeletal system?
It is the thin layer of tissue that surrounds the cell. It protects the interior of the cell from its surroundings.
What is cell membrane?
Contracts and moves various parts of the body
What is muscle tissue?
Eliminates waste from the body, reducing the buildup of toxins
What is the Excretory system?
It is the process of cell reproduction that occurs when the cell divides into two identical daughter cells.
What is Mitosis?
Protects the body from disease by developing immunities and destroying pathogens and toxins
What is the Immune (lymphatic) system?
It is the process of simple molecules combining to form a complex molecule. Anabolism requires energy.
Anabolism
Provides a protective covering and regulates body temperature
What is the Integumentary system?
It is the process of breaking complex molecules down into simple molecules. Catabolism releases energy.
Catabolism
Covers, shapes, and holds the skeletal system in place; muscles contract to allow for movement of body structures
What is the Muscular system?
