Looking Inside Cells & Plant Cell Organelles Quiz

The correct answer is Nucleolus. The description provided in the question matches the characteristics of the nucleolus. The nucleolus is a dark purple sphere found within the nucleus, which is represented by the larger sphere in the diagram. It is responsible for producing ribosomes and their RNA.

Organelle #3 is described as a large membrane-bound space within the plant cell that takes up much of the cell. It helps maintain the shape of the cell and stores water and waste liquids. The organelle that fits this description is the vacuole, which is a fluid-filled sac surrounded by a membrane found in plant cells. The vacuole is responsible for maintaining turgor pressure, storing nutrients, and regulating the cell's internal environment.

Organelle #7 is described as a thin layer of protein and fat that surrounds the inside of the cell, inside the cell wall. This membrane is passable, allowing some substances to pass into the cell and blocking others. The correct answer is the Cell Plasma Membrane, which fits this description.

Organelle #10 is the Golgi Bodies. The Golgi Bodies are flattened, folded, pancake-like structures located near the nucleus. They are responsible for packaging proteins and carbohydrates into membrane-bound bubbles for use and "export" in and from the cell.

Organelle #4 is chloroplasts. Chloroplasts are green bean-shaped organelles that contain chlorophyll. They are responsible for photosynthesis, which is the process of converting sunlight into chemical energy (food) for the plant.

The correct answer explains that organelles are tiny structures inside a cell that carry out the functions of the cell. This means that organelles are responsible for performing specific tasks within the cell, such as protein synthesis, energy production, and waste removal. They are like the organs of a cell, each with its own specialized function, working together to ensure the cell's survival and proper functioning.

Organelle #12 is the nucleus. The description states that it is a purple sphere that contains many smaller organelles. This matches the appearance of the nucleus, which is a spherical structure found in the cell. The nucleus is responsible for controlling many of the cell's functions and contains DNA in the form of chromatin or chromosomes.

The description provided matches the characteristics of a centrosome. The yellow ball with spikes represents the centrosome, which is responsible for organizing microtubules and plays a crucial role in cell division. The dense center and radiating tubes are indicative of the structure of the centrosome.

Organelle #17 is the cytoplasm. The cytoplasm is the jelly-like material that surrounds the organelles within the cell. It provides support and protection for the organelles and helps to maintain their shape. It also acts as a medium for cellular processes to occur, such as protein synthesis and metabolism.

Organelle #15 is described as the outer covering of the purple sphere, separating it from the other organelles and protecting it. The organelle that fits this description is the nuclear membrane, which surrounds the nucleus of a cell and separates it from the cytoplasm and other organelles.

The correct answer is Smooth Endoplasmic Reticulum because it is described as a thin, blue ribbon-like, non-grainy structure in the diagram. The other organelles listed in the word bank do not match this description.

Organelle #9 in the plant cell diagram is the mitochondria. The description matches the characteristics of mitochondria, as it is bean-shaped with a double membrane, and the inner membrane is folded multiple times. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through cellular respiration. They break down sugars and convert them into ATP, which is used as a source of energy for various cellular activities.

Organelle #16 is described as a thick, blue, folded, snaking-ribbon-like organelle that is a continuation of the nuclear membrane and is covered with tiny grains of protein. This description matches the characteristics of the Rough Endoplasmic Reticulum. The Rough ER is responsible for protein synthesis and transportation within the cell, which aligns with the statement that this organelle produces proteins and transports materials throughout the cell.

Organelle #8 in the plant organelle diagram is described as a small, oval, grey structure that helps control chemical change in cells. It converts fatty acids into sugars and plays a role in photosynthesis. This description matches the characteristics of peroxisomes, which are small organelles involved in various metabolic processes, including lipid metabolism and detoxification reactions.

Ribosomes are small, black, grainy structures that are made in the nucleolus. They can be found floating in the cytoplasm or attached to the rough endoplasmic reticulum. Therefore, ribosomes match the description given for organelle #2 in the diagram.

Organelle #14 is described as a tiny, black dot inside of the purple sphere. This structure is made up of DNA (the chromosomes) that contains the cells' genetic material. This description matches with the characteristics of chromatin, which is the material that makes up chromosomes and contains the genetic information of the cell.

Organelle #18 is identified as chlorophyll. Chlorophyll is a pigment found in chloroplasts, which are responsible for giving plants their green color. Chlorophyll plays a crucial role in photosynthesis, where it absorbs sunlight and converts it into energy in the form of glucose and oxygen. Therefore, the description provided in the question matches the characteristics of chlorophyll.

Organelle #6 is described as a thick, rigid membrane surrounding and framing the plant cell. This matches the characteristics of the cell wall, which is a rigid structure that provides support and protection to the plant cell. The cell wall is made up of cellulose and other materials, and it bonds with other cell walls to form the structure of the plant.

Organelle #5 is described as small tube-like organelles that are like channels in the cell wall, crossing between plant cells. These tubes are called plasmodesmata and they allow for communication and transport between plant cells.

Chromatin is important to the cell because it contains genetic material (DNA), which provides the instructions for directing the cell's functions. DNA carries the information necessary for the cell to carry out essential processes such as growth, development, and reproduction. By condensing and packaging the DNA into chromatin, the cell is able to tightly regulate gene expression and ensure that the appropriate genes are activated or repressed at the right time. This allows the cell to maintain its proper functioning and adapt to different environmental conditions.
