Cell Structures & Functions Biology Quiz

Plant cells, like all other cells in organisms classified as Eukarya, are eukaryotic cells. Prokaryotic cells, on the other hand, lack a true nucleus and other membrane-bound organelles found in eukaryotic cells.

Animal cells are eukaryotic cells, which means they have a defined nucleus enclosed by a membrane, as well as other membrane-bound organelles within the cytoplasm. Prokaryotic cells, on the other hand, lack a defined nucleus and other membrane-bound organelles.

Cytoplasm is the semi-fluid substance inside a cell where most cellular activities occur. While the nucleus houses the DNA and controls cell activities, mitochondria are responsible for energy production, and the endoplasmic reticulum is involved in protein synthesis and transport.

Plasmids are small, circular, double-stranded DNA molecules that are separate from the chromosomal DNA and can replicate independently within a bacterial cell.

The cell wall is a rigid layer that surrounds the cell membrane providing structural support and protection. The cell membrane controls the movement of substances in and out of the cell, the nucleus contains genetic material, and the cytoplasm is the gel-like substance inside the cell where organelles are suspended.

Bacteria cells are prokaryotic, meaning they lack a distinct nucleus and other membrane-bound organelles found in eukaryotic cells. Eukaryotic cells, on the other hand, have a true nucleus and membrane-bound organelles.

Photosynthesis occurs in the chloroplasts of plant cells where chlorophyll captures sunlight and converts it into energy. The other organelles listed, such as the Endoplasmic Reticulum, Mitochondria, and Golgi Apparatus, do not play a direct role in photosynthesis.

Mitochondria are known as the powerhouse of the cell and play a crucial role in aerobic respiration by producing ATP through the process of cellular respiration. Chloroplasts are responsible for photosynthesis, not aerobic respiration. Endoplasmic Reticulum is involved in protein synthesis and Golgi Apparatus is responsible for packaging and distributing molecules within the cell, not directly involved in aerobic respiration.

Anaerobic respiration occurs in the cytoplasm of the cell, where glucose is broken down to generate energy in the absence of oxygen. The other cell parts mentioned - Mitochondria, Nucleus, and Endoplasmic Reticulum - are not directly involved in anaerobic respiration.

Ribosomes are the cellular organelles responsible for protein synthesis. Mitochondria are known as the powerhouse of the cell, Golgi Apparatus is involved in modifying, sorting, and packaging proteins, and Endoplasmic Reticulum plays a role in protein synthesis and lipid metabolism, but ribosomes are specifically responsible for protein synthesis.

The cell membrane, also known as the plasma membrane, is a semipermeable lipid bilayer that surrounds the cell and controls the movement of substances in and out of the cell. While the nucleus functions as the control center of the cell, mitochondria are responsible for energy production, and the endoplasmic reticulum is involved in protein and lipid synthesis.

The nucleus is responsible for controlling the cell as it contains the cell's genetic material and controls the cell's activities. The mitochondria are known as the powerhouse of the cell, the Golgi Apparatus is involved in processing and packaging proteins, and the Endoplasmic Reticulum is responsible for protein synthesis and lipid metabolism.

Eukaryotes are organisms whose cells contain a nucleus with chromosomes enclosed by a membrane. This distinguishes them from prokaryotes, which do not have a nucleus. Single-celled organisms can be eukaryotic or prokaryotic, so it is a broad category. Mitochondria are organelles within eukaryotic cells, not the name given to cells with chromosomes enclosed by a membrane.

Chloroplasts are primarily found in plant cells, where they are responsible for photosynthesis. Animals, bacteria, and fungi do not typically contain chloroplasts.

Chromosomes are found within the nucleus of a cell, where genetic material is stored and maintained.

The image shows a structure with green pigmentation, indicating the presence of chlorophyll. This matches the characteristics of a chloroplast, which is responsible for photosynthesis in plant cells.

Plant cells have a rigid cell wall, while animal cells do not. The cell wall provides support and structure to plant cells, allowing them to maintain their shape and protect the cell. Animal cells do not have a cell wall, but instead have a flexible cell membrane that gives them a more dynamic shape.

Ribosomes are the cellular organelles responsible for protein synthesis, whereas mitochondria are the powerhouse of the cell, endoplasmic reticulum is involved in protein synthesis and transport, and Golgi apparatus is responsible for processing and packaging proteins.

Microtubules are long, hollow cylinders made up of tubulin proteins and play a crucial role in cell movement, cell division, and intracellular transport. Actin filaments and intermediate filaments are other components of the cytoskeleton but do not fit the description provided. Ribosomes are not protein tubules involved in cellular scaffolding or movement.

Flagella are long, whip-like structures that help cells move. Cilia are also cellular structures used for movement but are shorter and more numerous. Ribosomes are involved in protein synthesis within the cell. Mitochondria are the powerhouse of the cell responsible for energy production.

The cytoplasm is the semifluid substance within cells, while the nucleus, mitochondria, and cell wall are distinct cell components with different functions.

The cuticle is a waxy layer secreted by epidermal cells of plants that acts as a barrier to prevent water loss. Collagen is a structural protein found in animals, chlorophyll is a pigment involved in photosynthesis, and melanin is a pigment that provides color in animals.

The nucleus is the organelle with two membranes that holds the cell's DNA in a eukaryotic cell. Mitochondria are responsible for energy production, endoplasmic reticulum is involved in protein and lipid synthesis, and chloroplasts are found in plant cells and are responsible for photosynthesis.

The extracellular matrix is the substance in which animal cells are embedded, which contributes to the structural support and communication between cells.

Mitochondria is known as the powerhouse of the cell because it is responsible for producing the energy currency of the cell, ATP.

Microfilaments, also known as actin filaments, are the reinforcing cytoskeleton elements responsible for functions related to cell movement.
