Cell structure

• What are the 3 types of cells ?

  Bacterial Cell

  Animal Cell

  Plant cell
• A single circular chromosome containing DNA is found within the cytoplasm.
• It has a plasma membrane that surrounds the cytoplasm which contains ribosomes where proteins are made.
• The bacterial cell is prokaryotic, meaning it does not have a nucleus or membrane-bound organelles.

• What structure starting with an L is found on an animal cell

  lysosomes
• Do animal cells have a large permanent vacuole?

  No
• What are two other features of animals?

  They often store carbohydrates as glycogen

  They usually have nervous coordination
• What are 3 other features of plants?

  They feed by photosynthesis

  They store carbohydrates as starch or sucrose

  They do not have nervous coordination
• What structures do both animal and plant cells contain?

  Cell membrane, Cytoplasm, nucleus,mitochondria
• What structures do plant cells have that animal cells dont?

  Large permanent vacuole, Cellulose cell wall, Chloroplasts
• What is the function of a nucleus?

  contains genetic material(DNA) and controls activities of the cell
• What are 2 features of a nucleus?

  Nuclear membrane and pores
• What does the cell membrane do?

  It is selectively/partially permeable and controls substances moving into and out of the cell.

  Holds the cell together seperating the inside of the cell, from the outside
• What does the cytoplasm do and what is it?

  The cytoplasm is a gel-like substance inside the cell that holds the organelles and provides a site for chemical reactions. It supports cell structure.
• What are ribosomes made of ? What do the ribosomes do and where are they found?

  They're the site of protein synthesis and located in the cytoplasm

  They are made of RNA and Protein
• What are the mitochondria?

  The site of aerobic respiration(to release energy)

  Cells with high metabolic rates have large numbers of the
• What is the cell wall?

  It is a cellulose wall that gives the cell extra support and defines its shape.
• What are chloroplasts?

  They are organelles that trap sunlight to create food for photosynethesis. They contain chlorophyll which is what makes them green
• What are plasmids?

  Plasmids are small circular pieces of DNA. Commonly found in bacteria, but also present in other prokaryotes. Plasmids often carry genes that confer antibiotic resistance on their host cells.
• What does the vacuole do?

  It stores cell sap

  and is used to store usefull materials

• What is the function of the flagellum?

  To help with movement
