present in an animal cell. These three organelles found in a plant cell are: a cell wall‚ chloroplasts and a vauole. An animal cell does not need a cell wall because it does not need to keep a strong shape like a plant cell‚ an animal cell does not need chloroplasts because they are what absorb the light to enable the plant to go through photosynthesis whereas an animal cell does not need to go through photosynthesis they need to take in oxygen to survive‚ a plant cell takes in carbon dioxide and releases

they can source water whereas fungi can live almost anywhere so long as it has other small organisms nearby. Plants make their own food‚ using water and carbon dioxide to make glucose (energy) and oxygen (a waste product) in a process called photosynthesis. Though very little of it‚ it also lets out some carbon dioxide. This is the reason that it has adapted to live in places with lots of sunlight- so it can absorbed enough of it to make energy. It also grows in ground that has a water source. Different

But‚ we noticed that light energy cannot be directly used by the plant. So‚ using the process of Photosynthesis plants can effectively turn light energy into “usable” or kinetic energy. This process consists of two sub-processes‚ light dependent and light independent. In a plant cell there is an organelle called the chloroplast. In each plant cell there are tons of chloroplasts‚ and in these chloroplasts there are little thylakoids which are little green disks. The thick skin of the thylakoid is called

affect the pathways and the rate of photosynthesis in plants The following report is about the factors which can affect the pathways and the the rate of photosynthesis in plants. This report will cover what photosynthesis is ‚ the factors which may affect photosynthesis in working poorly‚ light independant and dependant reaction. An investigation will be carried out which will include the factors that affect photosynthesis. What is photosynthesis? Photosynthesis is a process which occurs in plants

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein
