Cells and Organelles Function

Cells

most basic unit of life

Tissues

collection of like cells

Organs

multiple tissues working together

Organ System

a group of organs that serve a function

Organism

individual life form

Benign tumor

not cancerous; no metastasis

Malignant tumor

cancerous; undergoes metastasis

Mitochondria

powerhouse of the cell

Nucleus

control center of the cell which contains genetic material

Cell membrane

encloses cell contents; keeps unwanted substances out

Nucleolus

produce and assemble the cells ribosomes

Smooth ER

enzymes speed up reactions involved with metabolizing lipids

Rough ER

creates proteins

Capsule

protect bacteria from attack of white blood cells; keeps cells from drying out; help bacteria attach to other cells

Cell wall

provides protection to the cell; provides circulation, water, and minerals

Vacuole

storage structure in a cell; holds food for later use; maintains water balance

Lysosomes

Digest biological molecules

Glycoprotein

reproduction, immune system, hormones, and protection of cells and organisms

Peripheral protein

support, communicate, enzymes, and molecule transfer in the cell

Chromosomes

carry gene traits; determines the genetic sex

Cytoplasm

provides a platform upon which other organelles can operate within a cell

Cilia

help the cell move around; prevent debris and possible pathogens from invading the body

Cytoskeleton

provides structure and support; organelle transport; cell division

Flagella

enables many protozoa, bacteria and spermatozoa

Transmembrane protein

connect cells together; act as enzymes

Ribosome

translates genetic code into amino acids that form proteins

Golgi body

separates proteins; creates new proteins
