cell parts and cell size

Organelles

structures within a cell that have a specific function

Selectively Permeable

allowing only certain materials to pass through it and not others.

Cell membrane

the selectively permeable structure that covers the contents of a cell. it determines what is able to move into and out of a cell

nucleus

it controls all of the cells activities. It contains DNA which direct the cells growth and reproduction. it is cover by a nucleus membrane

Cytoplasm

a gel like substance located throughout a cell thathelps contain and support the structure of a cell

Vacuole

a balloon like fluid filled organelle that stores water, food, wastes, and other materials

Endoplasmic Reticulum

a folded membrane that forms a system of canal like structures that transport materials to different parts of a cell

Cell wall

only occur in the cells of plants and fungi. They are much thicker and more rigid than the cell membranes of aninal cells and are made mostly of a tough material called cellulose. They provide support for the cell.

chloroplasts

enables plants to make carbohydrates through the process of photosynthesis. it is only found in plants. it contains chlorophyll

golgi body apparatus

the three primary functions of gba are the transport, sorting, and modification of both protein and lipid

ribosomes

responsible for making proteins

cell size

cells are extremely small in diameter, they usually run 1 to 5 micrometers in diameter, a smaller cell takes less energy to function

Mitochondrion

an oval shaped organelles that transforms energy for the cell. Tiny food particles are broken down to release their chemical energy for the cell to perform its activities
