slide3
The nucleus, like all cell organelles, are surrounded by a membrane to separate from other internal cellular structures and the cytoplasm.

The nucleus, like all cell organelles, are surrounded by a membrane to separate from other internal cellular structures and the cytoplasm.

Ribosomes are made by the nucleolus within the nucleus. Therefore, the ribosomes must leave the nucleus before they can do their jobs within the cytoplasm as free floating ribosomes or while attached to endoplasmic reticulum as rough ER.
smooth endoplasmic reticulum
Smooth endoplasmic reticulum

Smooth endoplasmic reticulum is responsible for synthesizing fats (lipids) in the cell and detoxifying some harmful chemical such as alcohol

slide18
Vesicles transport membrane bound packages of cell materials within the cell between other membrane bound cell structures like the ER , golgi apparatus and cell membrane.

Specialized vesicles become lysosomes or peroxisomes.

slide23
Membrane bound structures within the cell ‘communicate’ with each other by passing substances throughout the interconnected membranes.
slide26
Aerobic respiration occurs within the mitochondria. This process produces ATP (adenosine tri phosphate), the cell’s chemical energy.
slide27
Cytoskeleton is made up of various protein structures that either give a cell shape/structure OR allow for transport of the cell or substances within the cell – for example chromosomes during mitosis.
slide35
The contractile proteins (actin and myosin) of your skeleton muscles are examples of cytoskeleton structures.
