The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid

Cell Fusion Introduction: The fusion of cells is a fundamental biological event that is essential for a variety of developmental and homeostatic processes. The importance of cell-cell fusion during development and disease is displayed in a variety of biological processes including‚ but not limited to‚ fertilization‚ development of tissues‚ the immune response‚ and aspects of tissue regeneration due to stem cells (Chen and Olson‚ 2005). Fertilization‚ which is the fusion of sperm and egg‚

the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical
