Organisms that aren’t food producers must be food consumers. This method of nutrition is described as heterotrophic (eating others). Consumers include: predators‚ parasites‚ scavengers‚ decomposers and some green plants (e.g. sundews‚ Venus flytrap‚ pitcher plants). The food sources may be all or any of: plants‚ animals‚ fungi or bacteria; either living or dead. The advantages of the heterotrophic method of nutrition are: the food usually contains all the appropriate chemicals needed by

Investigating the effect of salt concentration in beetroot at different temperature Abstract The aim of the experiment is to find out the effect of salt concentration in a beetroot at a different temperature. The experiment will help to identify the effect of salt concentration in beetroot at different temperatures. After this‚ equipment called colorimeter will be used to take a reading for absorbency. The readings for the absorbency will be repeated three times in order to find the mean of

4. Which of the following structures are present in both prokaryotic and eukaryotic cells? Plasma Membrane- present in both cell types Golgi Apparatus- not present in the prokaryotic cell‚ present in the eukaryotic cell DNA- both have DNA Lysosomes and peroxisomes- prokaryotic cells do not have either‚ eukaryotic cells contain both Cytoplasm- both contain cytoplasm 5. Where is genetic material found in plant cells? Found on the DNA within the plants nuclei cells. 6. Mitochondria

There is also a deep oral groove containing inconspicuous compound oral cilia (as found in other peniculids) used to draw food inside. They generally feed on bacteria and other small cells. Osmoregulation is carried out by a pair of contractile vacuoles‚ which actively expel water from the cell absorbed by osmosis from their surroundings. Paramecia are widespread in freshwater environments‚ and are especially common in scums. Recently‚ some new species of Paramecia have been discovered in the oceans

actual prison wall. The prison wall surrounds the prison like the cell wall is a stiff wall that surrounds the membrane‚ giving the cell a rigid‚ box like shape. Another resemblance is between the vacuole and storage rooms. The storage rooms stores food‚ water‚ for the inmates to eat later like the vacuole stores water‚ food‚ waste products‚ and other materials. In addition‚ a correspondence could be between the mitochondria and the prison generator. The Prison Generator is where all the prisons energy

Practical Assessment Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot
