Organelles

Structure & Function

Plasma

Structure-Double layers of phosphollips the outer surface of the cell

Function-Separates the content of the cell from its outer environment and it regulates when enters.

Cell Wall

Structure-the outer layer


Function-provide protection and support for the plant

Cytoplasm

structure- fluid like jelly where the cellular organelles are suspended.


Function-The cytoplasm is the place where the cell expands and growth of the cell takes place. The cytoplasm provides a medium for the organelles to remain suspended.

Nucleus

Structure-The nucleus is the largest organelle of the cell. Holds DNA. It occupies about 10% of the total volume of the cell.


Function-the nucleus controls the cell activities

Nuclear Membrane

Structure-The nuclear membrane consists of two lipid bilayers,the inner nuclear membrane, and the outer nuclear membrane.


Function-The nuclear membrane has many small holes called nuclear pores that allow material to move in and out of the nucleus

Nucleolus

Structure- The dark cylinder shape inside of the Nucleus


Function- Nucleoli are made of proteins and RNA and form around specific chromosomal. Which makes Ribosomes.

Centrioles

Structures-Centrioles is made u of a cylinder of microtube pairs


Function-In higher animal cells the centrioles form the mitotic poles. It seperates the cromosones

Chromatin

Structure-The overall structure depends on the stage of the cell cycle. During interphase. the chromatin is structurally loose to allow access to RNA and DNA polymerases that transcribe and replicate the DNA.

Ribosomes

Structure-The ribosome is a cellular machine which is highly complex. It is made up of dozens of distinct proteins (the exact number varies a little bit between species) as well as a few specialized RNA molecules known as ribosomal RNA (rRNA).


Function-The ribosomes synthesizes the proteins

Golgi apparatus

Structure-A filled sack, squggling lines

Function-Cells synthesize a large number of different macromolecules. The Golgi apparatus is integral in modifying, sorting, and packaging these macromolecules for cell secretion

Endoplasmic Reticulum

Structure- Connects to the nucleus envelope and cell membran


Function- the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicle to the Golgi apparatus

Mitochondria

Structure- The inner membrane fold into cristae

Function- Mitochondria breaks down sugar for energy

chloroplast

Structure- Is like a green pigment


Function-Chloroplast releases oxygen

Lysosomes

Structure- Lysosomes are small and round with one single membrane


Function- Its function is to eat and get rid of other old cells

Vacuole

Structure- Vacuole is a large organelle inside of plant cells


Function- Its function is to store food, water and metabolic

Cytoskeleton

Structure- It is made of molecules migofilation


Function-It moves organelles through the cell
