Cell Parts Functions

cell membrane

monitors and controls entry into and out of the cell. The cytoplasm is the fluid that fills the cell.

Nucleus

It holds the DNA for the cell

vacuole

Large fluid filled space in a plant cell

cell wall

thick rigid layer surronding the plant cell.

mitochondria

produces energy to fuel the cell's activities, cellular respiration takes place here

chloroplast

The food producer for the plant cell, it converts the energy of the sun into sugar

Endoplasmic Reticulum

Aids in the transports of proteins made by ribosomes. Note, there is a smooth one and a rough one

Ribosomes

transport proteins

Golbi Aparatus

It aids in the modification, distribution and packaging of proteins made in the cell.

Centriole

They are only found in animal cells and they help chromosomes move during cell division

Peroxisomes

Small structures surrounded by a membrane, they contain the different types of enzymes used by the cell to produce energy.

Cellular Membrane

The cell (or plasma) membrane moniters and selectively controls entry into and out of the cell.

Cytoplasm

To maintain the shape and consistancy of the cell. It is the fluid that fills the cell

Plasmid

Small extra piece of circular DNA found inside bacteria

Flagella

whip-like tails that help bacteria move

Nucleoid

The region of Bacteria that contains DNA

Lysosome

They act as the digestive system in the cell, breaking down old and unneeded parts. They also break down substances brought from outside the cell.

Nucleolus

The part of the nucleus that makes the parts needed to build ribosomes

Nuclear Membrane

It controls what what enters and leaves the nucleus. Also called nuclear envelope.

centrosome

Area where microtubules are produced

Rough Endoplasmic Reticulum

Protein synthesis takes place here. It helps hold the shape of the cell togehter and transports materials. Chemical reactions also can occur on its surface.

Smooth Endoplasmic Reticulum

packages proteins for transport in vesicles, synthesizes membrane phosolipids, and releases calcium.

Cytoskeleton

Transport system that is also the protein structure in a cell and therefore prevents cells from collapse.

Nucleoplasm

The gel inside the nucleus that hold the DNA.

vesicle

A bubble like thing with an outer surface made of the same material as the outer surface of the cell, this bubble transports materials (mostly proteins) in and out of the cell. When something large and foreign in being brought in by the cell, it is enveloped in the wall which will wraparound it and let go of the stuff wrapping it, creating a vesicle.

Chromosomes

organized structures containing DNA and protei the nucleus that holds genetic material.. They are located in the nucleus as coiled strands of DNA.

Vacoule

They store food and waste, expel bad substances from the cell and maintain pressure/movement.
