membrane and therefore increased permeability. Beetroot contains a red pigment called betacyanin‚ which is located in the large central vacuole of the beetroot cells. The vacuole is enclosed by a single membrane called the tonoplast and the whole cell is enclosed by the cell membrane made up of phospholipids and proteins. Betacyanin will remain inside the vacuoles of intact cells. However‚ if the membranes are damaged‚ betacyanin will leak out and produce a red/dark pink colour in the surrounding

INTRODUCTION: Osmosis is defined as the net movement of water or any other solutions molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium

amount of a reddish betacyanin pigment‚ called betanin. This pigment is synthesized in the cytoplasm‚ and then transported across the tonoplast against its concentration gradient where it is accumulated and stored in the vacuole. In healthy cells the pigment remains in the vacuole‚ but some treatments that alter membrane permeability causes the betanin to leak out of the cells. 4.4 Experimental Procedures 4.4.1 Factors Affecting Permeability of Red Beet Root Membranes Cut a

QUESTIONS AND ANSWERS SECTION A: SIMILARITIES‚ DIFFERENCES‚ AND DEFINITIONS Gametes are mature haploid reproductive cells that unite to form a zygote that develops into a new individual. Gametes are also called sex cells. An egg or ovum is a haploid female reproductive cell or gamete whereas a sperm is a male haploid reproductive cell. A zygote is the initial cell that is formed as a result of the union of a male and a female gamete by means of sexual reproduction. The two haploid cells merge

of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim of this practical is to use beetroot to examine the effect of temperature on cell membranes and relate the effects observed

Introduction I chose this topic for my experiment‚ because my mother has always been very interested in taking care of flowers and growing them form seeds to adults. We have many different plants in our home and every one of them has different watering and fertilizer instructions‚ which need to be followed in order to make the plant grow and develop as safely as possible. Every plant has unique features and appearance‚ which makes them intriguing. Even the individuals from one specific species can

Information from research states that the beetroot cell membrane contains a large central vacuole containing a red pigment anthocyanin‚ which gives the beetroot its colour. When the beetroot cell has been disturbed or stressed such as cutting or in the case of this investigation‚ increasing the temperature‚ the beetroot’s inner vacuole
