slide 7) 1) Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape
2). The largest cells is an egg cell of ostrich. The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm. The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich. The longest cell is the nerve cell
3). Although different cells are in different shape and sizes, not all of them can shift or change their shape and sizes. The cell present in our body that can change its shape is red blood cells and the white blood cells. As they move through narrow blood vessels, they can change their shape to improve locomotion
Slide 8). 1)
Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton (Table 1.1). In spite of these differences, the same basic molecular mechanisms govern the lives of both prokaryotes and eukaryotes, indicating that all present-day cells are descended from a single primordial ancestor. How did this first cell develop? And how did the complexity and diversity exhibited by present-day cells evolve
