Plant Cell Organelles: Structure And Function Test

Chlorophyll is the correct answer because it is the green pigment found in the chloroplasts of plants. It plays a crucial role in photosynthesis, where it absorbs light energy and converts it into chemical energy. Chlorophyll is responsible for giving plants their green color and is essential for their ability to capture sunlight and produce glucose.

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

The correct answer is the nucleolus. The nucleolus is a small, dark purple sphere found within the nucleus of a cell. It is responsible for producing ribosomes and their RNA.

Organelle #4 is described as a green, bean-shaped organelle that is involved in photosynthesis. This matches the characteristics of chloroplasts, which are responsible for converting sunlight into chemical energy (food) for the plant through photosynthesis. Chloroplasts contain chlorophyll, the pigment that gives them their green color and is essential for capturing sunlight. Therefore, the correct answer is chloroplasts.

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 cell's genetic material. Chromatin refers to the combination of DNA and proteins that make up chromosomes, so it is the correct answer in this context.

Cytoplasm is the jelly-like material outside the cell nucleus in which the organelles are located. It is a semi-fluid substance that fills the space between the cell membrane and the nucleus. The cytoplasm contains various organelles such as mitochondria, ribosomes, and the endoplasmic reticulum, among others. These organelles perform specific functions necessary for the cell's survival and are suspended in the cytoplasm. Therefore, the correct answer is Cytoplasm.

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. Vacuoles are membrane-bound sacs that are found in plant cells and are responsible for storing water, nutrients, and waste materials. They help maintain turgor pressure and provide structural support to the cell.

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 producing energy, synthesizing proteins, and storing genetic material. They are like specialized compartments within the cell that work together to ensure the proper functioning and survival of the cell.

Organelle #9 is described as a bean-like, oval structure with a double membrane that has an inner membrane folded many times. This organelle is known as the mitochondria, which is the energy powerhouse of the cell. It is involved in breaking down sugars (food) during photosynthesis to produce energy that the cell can use. Additionally, the mitochondria also stores and releases energy as needed by the cell.

The endoplasmic reticulum is the correct answer because it is an organelle that has two distinct parts. One part, called the rough endoplasmic reticulum, is covered with ribosomes which are responsible for protein synthesis. The other part, called the smooth endoplasmic reticulum, is a network of passageways that transport materials, such as lipids and proteins, from one part of the cell to another. Therefore, the endoplasmic reticulum fits the description given in the question.

Organelle #12 is the nucleus. The description of a purple sphere that contains many smaller organelles and controls many cell functions matches the characteristics of the nucleus. The nucleus is responsible for storing and protecting the DNA, which is found in the chromosomes.

Chromatin is important to the cell because it contains the genetic material (DNA) which carries the instructions for the cell's functions. DNA is responsible for encoding the proteins that are essential for the cell's structure, metabolism, and overall functioning. The thin strands of chromatin help to package and organize the DNA, allowing for efficient storage and retrieval of genetic information. Therefore, chromatin plays a crucial role in maintaining the integrity and functionality of the cell.

Chlorophyll is the correct answer because it is the only organelle related to photosynthesis and is responsible for the green color in plants. The other options listed are not directly related to photosynthesis or the green color of plants.

The Golgi bodies, also known as the Golgi apparatus, are responsible for packaging proteins and carbohydrates within the plant cell. These organelles receive proteins and carbohydrates from the endoplasmic reticulum and modify them by adding necessary molecules. The Golgi bodies then package these modified proteins and carbohydrates into vesicles and transport them to the cell membrane for export out of the cell. Therefore, the Golgi bodies play a crucial role in the export of proteins and carbohydrates from the plant cell.

Organelle #6 is described as a thick, rigid membrane surrounding and framing the plant cell, which bonds with other cell walls to form the structure of the plant. This description matches the characteristics of the cell wall, making it the correct answer.

Organelle #6 is described as a thick, rigid membrane surrounding and framing the plant cell, which bonds with other cell walls to form the structure of the plant. This description matches the characteristics of the cell wall, making it the correct answer.

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. This matches the description given in the question, making ribosomes the correct answer.

Organelle #16 is described as a thick, blue, folded, snaking-ribbon-like structure that is a continuation of the nuclear membrane and is covered with tiny grains of protein. This organelle is responsible for producing proteins and transporting materials throughout the cell. The only organelle that fits this description is the Rough Endoplasmic Reticulum, which is studded with ribosomes on its surface, giving it a rough appearance. Therefore, the correct answer is Rough Endoplasmic Reticulum.

Centrosomes are the correct answer because they are organelles found in plant cells that contain a dense center and radiating tubes called microtubules. During cell division, centrosomes play a crucial role in organizing the microtubules and spindle fibers, which help in the separation of chromosomes and the movement of genetic material to opposite sides of the dividing cell. This ensures that the cell can divide its material into two equal parts and form two daughter cells.

The correct answer is Smooth Endoplasmic Reticulum. The given description mentions that #1 is modeled as a thin, blue ribbon-like, non-grainy structure. This matches the characteristics of the Smooth Endoplasmic Reticulum, which is a network of tubules that lacks ribosomes on its surface.

Organelle #10 is the Golgi Bodies. The Golgi Bodies are flattened, folded, pancake-like structures located near the nucleus, but not attached to it. They are responsible for packaging proteins and carbohydrates into membrane-bound bubbles for use and export in and from the cell.

Organelle #8 is described as a small, oval, grey structure that helps control chemical change in cells. It specifically changes fatty acids to sugars and aids in photosynthesis. This description matches the characteristics of peroxisomes, which are small organelles involved in various metabolic processes, including the breakdown of fatty acids and the detoxification of harmful substances.

Organelle #5 is identified as plasmodesmata. Plasmodesmata are small tube-like organelles that are like channels in the cell wall, crossing between plant cells. These tubes allow for the transport and communication between plant cells, enabling the exchange of nutrients, signals, and other molecules.
