Life science encompasses all organisms, from the smallest, single-celled b acterium to the largest mammal on the planet, the blue whale. Life science encompasses all organisms, from the smallest, single-celled b acterium to the largest mammal on the planet, the blue whale. All organisms have characteristics, such as the need for energy to grow, interacti on with their surroundings, and the ability to reproduce. (All of these species, large and small, are made up of cells. All organisms share similarities, including the need for energy to grow , interaction with their surroundings, and the ability to produce offspring. ANSWER: The cell is the basic functional unit of an organism, which mean s that each cell has the capacity to fulfil all of that organism's activities. Additionall y, cells must develop from pre-existing cells. ANSWER: The cell is the basic functional unit of an organism, which mean s that each cell has the capacity to fulfil all of that organism's activities. Additionall y, cells must develop from pre-existing cells. 4 Points of a Cell - ANSWER 1. The initial part of a cell is the membrane. 2. The second component of a cell is the cytoplasm. 3. The third component of a cell is the nucleus. 4. The fourth component is made up of several organelles. 4 points for a cell - ANSWER 1. The initial component of a cell is the membrane. 2. The second component of a cell is the cytoplasm. 3. The third component of a cell is the nucleus. 4. All cells have four distinct parts. Cell membrane - ANSWER Cells are covered by a thin covering that isolates them from their surroundings. This membrane is known as the "cell membrane" (or plasma membrane) and serves as a barrier or wall. Cell membrane - ANSWER Cells are covered by a thin covering that isolates them from their surroundings. This membrane is known as the "cell membrane" (or plasma membrane) and serves as a barrier or wall. Cell membranes are semipermeable, which means that some chemicals can pass into and out of cells via the membrane. This permits the cell to absorb nut rients and remove waste materials. Cell membranes are semipermeable, which means that some chemicals can pass into and out of cells via the membrane. This permits the cell to absorb nut rients and remove waste materials. Cytoplasm, located inside the cell, is a semi-liquid substance in whi ch all of the cell's internal "organs" are dissolved. (This is where most of the cell's metabol ic activity takes place) Cytoplasm, located inside the cell, is a semi-liquid substance in whic h all of the cell's internal "organs" are dissolved. (This is where most of the cell's metabol ic activity takes place) The primary component of cytoplasm is - WATER. The primary component of cytoplasm is - WATER. Cells must produce DNA, the genetic material that causes a cell to proliferat e, and this DNA is stored in a specific location of the cell known as the nucleu s.
