Cell wall, mitochondria, chloroplasts, cell membrane, cytoplasm, vacuole, nucleus, ribosome 11 of 29 What structures are in a bacterial cell? Cell wall, cell membrane, ribosome , plasmid 12 of 29 What is the cell membrane made out of ? Phospholipids and proteins 13 of 29 Passive transport? Goes down a concentration gradient and does not require energy 14 of 29 Examples of passive transport? Diffusion and osmosis 15 of 29 Why is diffusion important ? Oxygen to come in and carbon dioxide to come out 16 of 29 Whats is osmosis? The movement of water molecules from a high water concentration to a low water concentration through a selectively permeable membrane 17 of 29 After osmosis what happens to animal cells? They burst or shrink 18 of 29 After osmosis what happens to plant cells? They become turgid or plasmolysed 19 of 29 What is active transport? Against a concentration gradient and requires energy 20 of 29 What is the structure of DNA? A double stranded helix held together by complementary base pairs 21 of 29 What does DNA carry? The genetic info for making proteins 22 of 29 What are the 4 bases? Adenine, Cytosine , Guanine and Thymine 23 of 29 How do the base pairs pair up? A+T G+C 24 of 29 What does the sequence of bases along a strand determine? The genetic code 25 of 29 What do the base sequence determine? The amino acid sequence in proteins 26 of 29 What is a gene? The section of DNA that codes for a protein 27 of 29 What is mRNA? The molecule that carries a complementary copy of the gentic code from the DNA in the nucleus to the ribosomes, where the protein is assembled 28 of 29 Functions of proteins? Structural, enzymes , hormones, antibodies and receptors 29 of 29
