Answer:

Nucleus - controls all activities of the cell

Nucleolus (in the middle of the nucleus)

- the synthesis of ribosomes and RNA (ribonucleic acid)

Mitochondria (battery of cell) - oxidise glucose to release energy in the form of ATP ( adenosine triphosphate)

Edoplasmic reticulum

1. Smooth - synthesises lipids

2. Rough- Transport proteins synthesised by ribosomes

Golgi apparatus ( golgi body, or any golgi, is has many names)

- Acts as Centre for processing, packaging and transporting macromolecules such as proteins and carbohydratez

Ribosomes - sites of protein synthesis

Lysosomes- Break down macromolecules such as proteins, lipids etc

Vacuoles - store food substances, site for waste products

Centrioles - form spindle fibres during cell division

Cytoplasm ( the so call empty spaces in the cell)

- place where biochemical reactions occur

Plasma membrane

-control movement of substances in and out of the cell due to its semi permeable characteristics

Ok that's all for animal cells, but for plants cells, there is more

Cloroplast - site for photosynthesis

Cell wall - Maintains the shape of plant call, give support to cells
