What is the structure and function of the Nucleus?
Contains DNA . DNA wrapped around histones to form Chromatin. Has a Nuclear Envelope, which contains pores. Centre is Nucleolus – produces mRNA .

What is the structure and function of Endoplasmic reticulum?
2 types = Rough and Smooth. Rough Endoplasmic Reticulum has ribosomes on it, makes proteins. Smooth Endoplasmic Reticulum has no ribosomes on it, makes lipids/carbohydrates

What is the structure and function of golgi apparatus?
Modifies and packages proteins. packages them into vesicles for transport. digestive enzymes are placed into lysosomes

What is the structure and function of Mitochondria?
Site of respiration, releases energy, produces ATP .Has a double membrane, inner membrane folded into Cristae (increases surface area for enzymes) . middle called Matrix

What is a Plant Cell made of?
Organelles: nucleus, ER, golgi body, lysosomes, mitochondria, chloroplast, vacuole, ribosomes) . Cytoplasm (site of chemical reaction) .Cell Membrane (holds cell contents together.

What is the structure and function of Chloroplast?
Organelle for photosynthesis. Has double membrane . Contains discs called thylakoids . Thylakoids contain chlorophyll. Stack of thylakoids called granum. Thylakoids surrounded by a fluid called stroma

What is the structure and function of Vacuole?
Surrounded by a membrane called a tonoplast, contains Cell Sap (water, sugar, minerals)

What is Bacteria made of?
No nucleus – loose DNA in single loop and plasmid .No membrane bound organelles: smaller ribosomes, mesosomes – infolding of cell membrane for respiration. Cytoplasm. Cell Membrane & Cell Wall (made of murein). Some have a Capsule and flagella.

What is Virus made of?
DNA or RNA. Protein Coat called Capsid and Lipid Coat. Attachment proteins on outside . Infects host cells by attaching, send in their DNA which uses the cell to make the viruses components and uses the cell membrane to make lipid coat., producing co
