All living organisms need water. Most plants obtain water from the soil. State the pathway taken by water as it enters and passes through a plant. Use words from the list to fill in the spaces. mesophyll cells root cortex cells root hair cells xylem vessels enters à à à Some of the water that enters the plant is used for transpiration. Define the term transpiration. State two ways a plant uses water other than for transpiration. shows apparatus that can be used to measure water loss in a plant. thermometer 325.0 g plant plastic bag pot of damp soil balance Suggest a reason why the pot of damp soil was placed inside a sealed plastic bag. The apparatus shown in was used in an investigation. The results of this investigation are shown in . Readings were taken at hourly intervals during the day between 9:00 and 16:00. 9:00 0.5 0.0 1.0 1.5 rate of water loss from 100 g of leaves / g per hour 2.0 temperature / °C 10:00 11:00 12:00 time of day 13:00 14:00 15:00 16:00 temperature water loss temperature water loss Use the information in to state: the maximum rate of water loss from 100 g of leaves g per hour the time at which the temperature was highest the maximum temperature reached during the investigation °C Describe the relationship between temperature and the rate of water loss from leaves shown in .

The four boxes on the left contain definitions of processes carried out by the alimentary canal. The six boxes on the right contain the names of processes. Draw a straight line to join each definition to the matching process. Draw only four lines. The breakdown of large, insoluble molecules into small, soluble molecules. The movement of digested food molecules into the cells of the body where they are used, becoming part of the cells. The passing out of food that has not been digested or absorbed, as faeces, through the anus. The taking of food substances, e.g. food and drink, into the body through the mouth. absorption assimilation chemical digestion egestion mechanical digestion ingestion definition process shows yeast being used to produce alcohol. A mixture of yeast and fruit juice is placed in a jar. Fruit juice contains sugar. A valve lets gas out of the jar but stops gas from entering the jar. valve gas escaping from the liquid jar mixture of yeast and fruit juice State the name of the process that the yeast uses to make alcohol. State the name of the gas produced when yeast makes alcohol. State the name of the gas that must be stopped from entering the jar when alcohol is being made. State the name of the group of chemicals that yeast uses to catalyse the breakdown of glucose molecules. Choose your answer from the list. antibiotics antibodies enzymes hormones

is a section of a flower that has both male and female parts. Parts of the flower are labelled with the letters L to S. L M N P Q R S Describe a function of each of the parts labelled L, N and Q. L N Q State the names of parts M, P, R and S. M P R S shows a mature maize plant. Maize plants have separate male and female flowers. Maize plants are pollinated by the wind. male flowers female flowers pollen Use the information in to describe how the position of the male and female flowers can increase the chance of pollination taking place. Describe two ways pollen from an insect-pollinated flower differs from pollen from a wind-pollinated flower.

shows an area of land where the trees have been cut down. List three undesirable effects of deforestation. Deforested land may be used for growing monocultures of crop plants. Describe the negative impacts to an ecosystem of large-scale monocultures of crop plants. Replanting trees in deforested areas can help to conserve endangered species. Describe two other ways that endangered species can be conserved.

is a label taken from a container of semi-skimmed milk. The milk is pasteurised and some of the milk fat has been removed. Fresh Pasteurised Semi Skimmed MILK Nutritional information per 100 cm3 of milk Energy 209 kJ Carbohydrate 4.8 g Fat 1.7 g Protein 3.6 g Fibre 0.0 g Salt 0.1 g gives information about five groups of nutrients. State two parts of a balanced diet that are missing from the label. State the name of the group of organisms that produce milk to feed their young. Describe the dietary importance of fats, carbohydrates and proteins in the human diet. fats carbohydrates proteins State the name of the element which is present in a protein but which is not found in fats or carbohydrates. Some doctors recommend that people with a risk of coronary heart disease should drink skimmed or semi-skimmed milk instead of whole milk. State two risk factors for coronary heart disease, other than diet.

shows the results of crossing a plant with red flowers with a plant with white flowers. offspring parents Key: red flowers white flowers Both of the parent plants were homozygous for flower colour. All of their offspring had red flowers. State what is meant by the term homozygous. The gene controlling flower colour in this plant species has two alleles: • R is dominant and represents the allele for red flowers • r is recessive and represents the allele for white flowers. Describe the evidence shown in that supports the fact that R is the dominant allele for flower colour in this species of plant. Another plant with red flowers was crossed with a plant with white flowers. Some of the offspring plants from this cross had red flowers and some of the offspring plants had white flowers. Complete the genetic diagram to show the results of this cross. red-flowered X white-flowered plant plant parental genotypes X parental gametes offspring genotypes offspring phenotypes
