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
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
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
