Parts of the Cell

Cell Membrane

Forms a barrier around cell contents and is semi-permeable to control the movement of substances in and out of cells

Cytoplasm

All material that surrounds other organelles within the confines of the cell membrane

Vacuoles (in human cells)

A small structures that store and transport nutrients and waste

Vacuoles (in Plant Cells)

Large central vacuole stores water, nutrients, and waste, helps maintain structure

Nucleus

Contains hereditary info in the form of DNA in chromosomes. Is considered the control and information centre

Nucleolus

Located inside the nucleus and is manufactures Ribosomal DNA, which plays a major role in protein synthesis

Mitochondria

Have a double membrane → increase surface area to increase amount of respiration to be carried out and releases energy as a product of Cellular Respiration

Chloroplasts

Contain chlorophyll → required to carry out photosynthesis

Golgi Body

Receive, sort, store and secrete materials such as proteins

Cell Walls

Plant cell walls are made of cellulose and provide rigid support

Lysosomes

Are membrane bound sacs which contain enzymes. Break down molecules such as fats, proteins and polysaccharides and recycle the unwanted material inside cell

Endoplasmic Reticulum

Involved in the transport of material. Rough, has ribosomes on its surface

and is the site of protein synthesis. Smooth → has no ribosomes. involved in the production of enzymes

Ribosomes

Carry out protein synthesis
