Anatomy and Physiology Chapter 2

Male sex gamete, smallest cell with a flagellum

Tails that allow cells to swim, and grant movement in liquids.

Human egg in reproduction

Material that fills the cell cavity allowing a place for organelles to float around

Tails that allow cells to swim, and grant movement in liquids.

Organelles mini organs in a cell

Organelle that contains the DNA of the cell.

specialized region of the nucleus to help manufacture proteins

Fluid in a cell where organelles rest.

Chemical compound that forms the genetic composition of an organism

Rod shaped bodies that contain genes in cell division

Specific molecules that receive chemical messages for the target cell

Cells that respond to the signals that are being sent

A unit of hereditary information

Hairlike organelles that allow the cell to move materials outside the cell

Steroid, phospholipid and fatty acid synthesis. Breaks down toxic chemicals.

Holds the ribosomes of the cell

Site of manufacturing proteins

Organelles that break down dead organelles and destroy bacteria

Protein processing and packaging plant

Carries out cellular respiration to produce energy for the cells function.

Electrons that become a toxic by product of cellular respiration

Process that breaks down fuel molecules in order to release the energy in them

Membrane allows certain materials to pass through, and prevents other materials from passing through.

Passage of water through a selectively permeable membrane that moves from a high concentration to a low concentration.

Movement of molecules from a high concentration to a low concentration

Passage of materials through a membrane by mechanical pressure

Moving materials from a low concentration to a higher concentration (uses energy)

Cell engulfs materials by surrounding them with a portion of its membrane (active transport)

Released chemicals used to regulate metabolism

Stasis, in between acts of division (mitoses).

First stage of mitosis: Chromatin comes together to form chromosome pairs (chromatids)

Second stage of mitosis: Chromatids are positioned along the cells equator

Third stage of mitosis: Chromatids divide, and begin to move to opposite ends of the cell

Fourth stage of mitosis: Chromosomes form two nuclei and the cell membrane constricts forming two daughter cells

Composed of one layer of cells

Epithelial cell: Flat cells shaped like pancakes

Epithelial cell: Short cylinders that are cubed from the side

Epithelial cell: Column shaped, thin and tall, nucleus is generally on the bottom

Unicellular gland that secrets mucus

Join other tissues in the body together. Provides support and protection

Tissues that store fat and release it when the body needs energy

Tissues that are designed to contract, used for locomotion

Tissues that form the walls of the heart

Tissue that lines the cavities in the body: Simple is one layer, Stratified is multiple

Lines body cavities that open to the outside (digestive tract) secretes mucus to remain moist

Lines cavities that do not open to outside (abdominalpelvic)

Solution where solute concentration is greater than that of the cell, causing dehydration

Involuntary muscles; that are not striated.

Fat Cells

Transmits information away from the cell body

Fibers that give the body structures strength. Most numerous of the fibers

Cells specialized for receiving impulses

Serous membrane that lines the abdominal cavity
