Animal cells and plant cells have features in common‚ such as a nucleus‚ cytoplasm‚ cell membrane‚ mitochondria and ribosomes. Plant cells also have a cell wall‚ and often have chloroplasts and a permanent vacuole. Cells may be specialised to carry out a particular function. Dissolved substances

BACTERIA. CLASSIFICATION Bacteria are extremely small and some can be just seen with the naked human eye. They are much smaller than eukaryotic cells but are still very complex despite their size. .the cell is surrounded by a cell membrane that enclosees the bacteria cell. They are single celled organisms. Bacteria are prokaryotic cells and therefore do not have a nucleus and do not have a lot of organelles like: mitochondria‚ chloroplasts‚ and other organelles that are usually found in eukaryotic

The seven processes of life The seven processes of life are the key to all living organisms: these processes consist of nutrition‚ growth‚ movement‚ respiration‚ reproduction‚ sensitivity and excretion. Although‚ they may be achieved in different ways depending on the organism. These processes happen with in both plants and animals; in each organ‚ cell and organelle. All these processes are interlinked and have a chain effect upon one another. Without one of them the others aren’t possible.

Biology – Preliminary – Evolution of Australian Biota 1. Evidence for the rearrangement of crustal plates and continental drift indicates that Australia was once part of an ancient super continent identify and describe evidence that supports the assertion that Australia was once part of a landmass called Gondwana‚ including: ▪ − matching continental margins ▪ − position of mid-ocean ridges ▪ − spreading zones between continental plates ▪ − fossils in common on Gondwanan continents

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living
Premium Protein Meiosis Chromosome
Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase
