Sex pili allow bacteria to exchange genetic information (plasmids) via bacterial conjugation • Bacterial cells divide by binary fission (asexual reproduction) • The circular DNA molecule is copied and then is anchored to the plasma membrane • The DNA loops are drawn apart as the cell elongates, before dividing (cytokinesis) to form two clones
Pads and supports organelles inside the cell. Moves by cyclosis. Small specks made of RNA. Found in cytoplasm or on the endoplasmic reticulum. Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once.
Every cell has a cell membrane. But some cells also have a cell wall. Plant cells, fungal cells, bacterial cells, and some protists have cell walls. A cell wall is a stiff structure outside the cell membrane. A cell wall protects a cell from viruses and other harmful organisms. In some plant and fungal cells, the
Basic Structure of Plant Cells. The bodies of all living things are made up of cells. The smallest living things are composed of just one cell. Bacteria and some algae are examples of one-celled living things but bacteria are neither plants nor animals.
Prokaryotes–Arrangements of Cells • Bacteria sometimes occur in groups, rather than singly. • bacilli divide along a single axis, seen in pairs or chains. • cocci divide on one or more planes, producing cells in: - pairs (diplococci) - chains (streptococci) - packets (sarcinae) - clusters (staphylococci). • Size, shape and arrangement ...
