    generalized eukaryotic plant cell. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Plants are unique among the eukaryotes. The interiors of plant cells‚ like all eukaryotic cells‚ contain numerous organelles‚ which are membrane bounded structures that close off compartments within which multiple biochemical processes can proceed simultaneously and independently. The cell membrane of the plant cell has a phospholipid bilayer

    roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

    Animal Cell There are two types of cells that exist. Prokaryotic cells are simple cells that have few organelles. These cells don’t have a nucleus‚ but do have DNA. The DNA acts as a sort of “blueprint” for growth and reproduction in the cell. Prokaryotes are things like Bacteria. Eukaryotic cells are a lot more complex than a prokaryotic cell. These cells are able to convert food to energy‚ break down waste products‚ digest food‚ and assist with reproduction of new cells. Eukaryotic cells are in

    Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes‚ when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications‚ or have a pattern of ongoing problems that shorten their lives. The most common and serious complications of sickle cell disease are anemia

    support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones. Bone cells are the living units that make up your bones and keep them functioning. Bone cells have two major roles‚ which are the production of new bones and resorption or destruction of old bone. They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves by

    Cell wall is a fairly rigid‚ protective and supportive layer surrounding the cell external to plasma membrane of plants‚ bacteria‚ archaea‚ fungi and algae. It is absent in animals and most protists. It was first observed by Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cellscell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)
