Nucleolus – A small organelle in the middle of the nucleus. Makes ribosomal RNA.

If missing, no RNA production. Ribosomes die. No protiens formed. Plant dies. Cell dies.

Nucleus – contains the nucleolus. Controls most funtions by production of proteins. Contains the DNA. Contains heriditary information and controlls the growth and reprodction.

If missing, cell cannot continue life processes. Cell dies.

Golgi body – Pakages the protiens etc, so they can be ‘exported’ from the cell. Located near the nucleus.

If missing, cannot move protiens. Plant gets no protiens. Plant dies. Cell dies.

Ribosomes - Large no. of organelles. Made from RNA-full cytoplasm granules. Sites of protien creation.

If missing, no protien formation. Plant dies. Cell dies.

Lysosomes – Bags containing digestive enzymes. Engulf food into a vacuole. Then they fuse with the vacuole, releasing into it its enzymes and digesting it.

If missing, cannot help with digestion. Poteintial for blockages etc.

Mitochondria – break down carbohydrates and sugar to make energy. Useful especially when there is no light, so the chloroplasts don’t make a energy.

If missing, no extra supply of energy, no backup if light is gone.

Rough and Smooth ER – A series of sacks and tubes. Transports materials through the body.

RER is covered in ribosomes and makes proteins.

SER contains enzymes, it makes and digests fats, it produces membrane protiens and it carries the protiens made by the RER to the golgi body etc.

If missing, no transport of anything. No protiens etc. Cell and plant dies.

Mircotubules – Forms one of the three main parts of the cytoskelton. Other parts are microfilimants and intermediate fibers.

If missing, cell and plant collapses and dies.

Cytoplasm – The collective term for the cytosol plus all the bits in it. It is mostly water, and transmitions through it use the protien in it. It is the jelly everything else sits in.

If missing, cell has no structure. Cell and plant collapses and dies.

Cell/Plasma membrane – Contain protien essential for survival, such as ones that are receptors for odur, tastes and hormones, or ones that control entry for ions (such as sodium etc).

If missing, lack of protiens essential for survival causes cell to no longer survive.

Vacuole – Large in plant cells. Stores nutrients. Stores waste products. Increases cell size during growth. Stores water to push out cell thereby keeping plant shape and preventing wilting.

If missing, plant will wilt and eventually die.

Chlorplast – contain and use all the chlorophyll (for photosyntesis). Responcible for green colour of plants.

Plastid – Can turn into one of the things shown on the chart. Each has a seperate property, such as fat storing or photosythesis.

Just imagine that a cell is this cute puppy. The skin is like the cell membrane, holding every thing inside and controlling what enters and exits. It’s brain is it’s nucleus, controlling all it’s life processes. The golgi body, mitochondria and ribosomes are the organs, which make proteins and the like. Lysosomes are the stomach, which dissolve food. The RER and SER are the blood vessels. They carry chemicals etc back and forth.The mircotubles are the bones of the cute puppy/ plant cell. Without these, the puppy would collapse into a disgusting mush like stuff. The blood/muscle etc is the cytoplasm. It’s the soup all else lives in. And finally, the vacuole is like the bladder of the dog. It makes up the major part of the cell/dog and is always full of liquid...
