ANSWERS:
1. Ans. A
Explanation: In 1665, the cell was first discovered by Robert Hooke. The cell has a rich and interesting history that has ultimately provided the way to various scientific advancements of today.2. Ans. C
Explanation: Golgi apparatus is also known as Golgi complex or Golgi body. It is an organelle that serves as a primary packaging area for molecules that will be distributed throughout the cell. It is located in the cytoplasm next to the endoplasmic reticulum and near the nucleus of the cell. 3. Ans. A
Explanation: Plasma Membrane is the outermost boundary of the cell. It is also known as the cell membrane. It is the membrane found in all cells that separate the interior of the cell from the outside environment. A cell wall is attached to the plasma membrane on its outside surface in bacterial and plant cells.4. Ans. D
Explanation: Endocytosis is the process in which the ingestion of material by the cells is done through the plasma membrane. Or we can say that it is the process of actively transporting molecules into the cell by engulfing it with its membrane.5. Ans. B
Explanation: Organelles are found in all Eukaryotic cells. They coordinate to produce the cell. They are small-sized and mostly internal. Organelle, any of specialised structures inside a cell that perform a specific function (e.g. mitochondria, ribosomes, endoplasmic reticulum). Organelles in unicellular organisms are the equivalent of organs in multicellular organisms.
