Animals and plants are ____. It means they have a nucleus encapsulated in a nuclear membrane. The nucleus is like the brain of the cell, containing ____ which store the genetic information. Aside from nuclear membrane, their cells also have a ____ , which acts as a selective gate to ensure only the necessary substance can go in and out of the cell. Inside the cell, many chemical reactions occur. One of them is ____ , in which cell use the nutrient molecule to produce ____ . Organelle responsible for this process is mitochondria, which have a folded inner membrane called ____ . The energy garnered from this process then will be used in other metabolism activities in cell. All the organelles are put together in a jelly-like structure called ____. ____ is the protein factory of the cell. It has ____ subunits with different size. It can be found free in the ____ or attached in the ____ , hence it is called ____ . The protein or other molecules synthesized by the organelles will be packed and transported by ____ . It will secretes ____ to transport the necessary molecules out of the cell. To be able to exit the cell, all of the molecules need to pass the ____ , which is a ____ structure. It means that only the selected molecules can go through the membrane. Plant is a ____ eukaryote, meaning that their body consists of more than one cell. As a fellow eukaryotes, plant have quite similar cell structure with animal. However, there are three major structure that distinguish these two. First is the presence of ____ , which gave the rigid structure to the plant cell. This structure can also be found in bacterial cells. In plant, it is made of ____ . In bacteria, it is made of peptidoglycan. The next difference is the ____ . The sap, food, and ____ will be stored in this structure. In plant, it is large and ____ . Actually both plant and animal have this structure, but the size is drastically small in the latter. In addition, it can only be produced by ____ when needed in animal cell, and it is called vesicle. The last difference is ____ , which contain the green pigment called ____ . This organelle is the primary site of ____ . Aside from plant, some algae also have this organelle. Bacteria is a kingdom that consists of ____ organisms. It means all of the bacteria is a single cell organism. They also have no nucleus, thus their DNA is not encapsulated in a nuclear membrane. This is why they are also called ____ . They have a chromosomal DNA floating in the ____ and sometimes some circular extrachromosomal DNA called ____ . Their cell wall are made of ____ . They do not posses any ____ , thus they adapt to make their energy through various mechanisms like anaerobic respiration. Some of them have tail-like structure that acts like their legs called ____ . Example of bacteria includes ____ and pneumococcus.
