An Interesting Quiz On Animal Cell

The cell membrane is the correct answer because it surrounds and encloses the cell, acting as a protective barrier. It regulates the movement of substances in and out of the cell, allowing for the exchange of nutrients and waste products. The cell membrane also plays a role in cell signaling and communication with other cells. Therefore, it is the organelle that is located around the outside of the cell.

The nucleus is the control center of the cell and contains genetic information in the form of DNA. It regulates all cellular activities and is responsible for the transmission of genetic traits from one generation to the next. The nucleus also plays a crucial role in cell division and replication.

The correct answer is the nuclear membrane. The nuclear membrane is a double-layered membrane that surrounds and protects the nucleus of a cell. It acts as a barrier, controlling the movement of substances in and out of the nucleus. The nuclear membrane is crucial for maintaining the integrity and function of the nucleus, as it separates the genetic material (DNA) from the rest of the cell's cytoplasm.

The correct answer is nucleolus. The nucleolus is a small, round structure found within the nucleus of a cell. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus contains DNA, RNA, and proteins, and it plays a crucial role in the assembly of ribosomal subunits. Therefore, out of the given options, the nucleolus is the only structure that is present in the nucleus and is directly involved in the production of ribosomes.

The correct answer is "releases energy from nutrients." Mitochondria are known as the powerhouses of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This process involves breaking down nutrients, such as glucose, and converting them into usable energy for the cell.

Ribosomes are responsible for protein synthesis, where proteins are manufactured. These small organelles are found in the cytoplasm of cells and also attached to the endoplasmic reticulum. They read the genetic information from the DNA in the nucleus and use it to assemble amino acids into proteins. Therefore, ribosomes are the correct answer for the location where proteins are manufactured.

Cytoplasm is the correct answer because it is the material that fills the space between the nucleus and the cell membrane. It is a gel-like substance that contains various organelles, such as mitochondria and centrioles, as well as other cellular components. The cytoplasm plays a crucial role in supporting the organelles, facilitating cellular processes, and providing a medium for chemical reactions to occur.

The rough endoplasmic reticulum is the correct answer because it is an organelle that is studded with ribosomes. Ribosomes are responsible for protein synthesis, and they attach to the rough endoplasmic reticulum to produce proteins that are then transported throughout the cell. The nuclear membrane is responsible for enclosing and protecting the nucleus, while the cytoplasm is the gel-like substance that fills the cell. Neither of these organelles have ribosomes attached to them, making the rough endoplasmic reticulum the only correct option.

Lysosomes are organelles found in cells that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a crucial role in digestion and recycling of cell particles. Lysosomes fuse with vacuoles or other organelles, releasing their enzymes to break down the contents. Therefore, lysosomes are responsible for digesting cell particles.

During cell division, centrioles play a crucial role in organizing the microtubules that form the spindle apparatus. The spindle apparatus helps in separating the chromosomes during cell division. Centrioles are small, dark bodies located outside the nucleus, and they are responsible for forming and anchoring the spindle fibers. Therefore, the correct answer is centriole.

The Golgi complex is responsible for storing and packaging chemicals within the cell. It receives molecules from the endoplasmic reticulum and modifies them by adding sugars and lipids. It then packages these molecules into vesicles and sends them to their appropriate destinations within or outside the cell. This organelle plays a crucial role in the sorting, processing, and distribution of cellular substances, making it the correct answer.

The vacuole is an organelle found in plant and fungal cells that functions as a storage structure. It stores various substances such as water, nutrients, and waste products. The vacuole also helps maintain the cell's turgor pressure, which is essential for plant cell structure and support. Additionally, it plays a role in regulating the cell's pH balance and detoxifying harmful substances. Therefore, the vacuole is the correct answer as it is specifically known for its storage function within the cell.

The smooth endoplasmic reticulum is responsible for various functions within the cell, including the synthesis of lipids and steroids, detoxification of drugs and toxins, and storage and release of calcium ions. It does not contain ribosomes on its surface, which is why it appears smooth under a microscope. The other options mentioned, such as lysosomes and cytoplasm, are not specifically related to the cell's internal transport system.
