eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also gives the cell its shape. The Nucleus or the brain

The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

In life’s hierarchy‚ cells make up the lowest level of organization. Cells can perform activities required to sustain life. A cell’s ability to divide to form new cells is the basis for growth and repair in organisms. Cells also play a key role in the recycling of carbon‚ a chemical element essential to life‚ and also participate in cellular processes such as photosynthesis. With these points in mind‚ it should be noted that cells come in one of two forms: prokaryotic and eukaryotic. By investigating

Plant Cell Plant cells are eukaryotic cells or cells with membrane bound nucleus. Generally‚ plant cells are larger than animal cells and are mostly similar in size and are rectangular or cube shaped. Plant cells are similar to animal cells in being eukaryotic and they have similar cell organelles. What is a Plant Cell?
