Different methods of transpiration… Water uptake from the soil: Plant roots are surrounded by soil particles. The outmost layer of cells (the epidermis) contains root hair cells that increase the surface area of the root These cells absorb minerals from the soil by active transport using ATP for energy The minerals reduced the water potential of the cell cytoplasm; this makes the water potential in the cell lower than that in the soil. Movement across a root: The movement of water across the

Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

What are the central ideas of Cells? • What are cells? – Cells are the smallest basic unit of living things. • What do they do? – Cells take in raw materials and making new substances. • Why do they do this? – In cells‚ organelles carry out activities to keep the organism alive. – E.g. synthesising proteins and fats‚ releasing energy from glucose. What are the central ideas of Movement of Substances? • What processes describe how substances move from one region to another? –

Adaptation Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Organisms can be adapted in two ways: 1. Body structure (e.g. Small ears to reduce heat loss) 2. Body processes (e.g. Osmoregulation in salmon) There are several factors which
