Where proteins are made

Cell membrane
Lysosomes
Ribosomes

Correct Answer

A. Ribosomes

Explanation

Ribosomes are responsible for protein synthesis in cells. They are small, spherical organelles found in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information encoded in DNA and use it to assemble amino acids into proteins. They are the site where translation occurs, converting the genetic code into functional proteins. Therefore, ribosomes are where proteins are made in cells.

Gives the cell shape, holds the cytoplasm, controls what moves in and out of the cell

Endoplasmic reticulum
Nuclear membrane
Cell membrane

Correct Answer

A. Cell membrane

Explanation

The cell membrane is responsible for giving the cell its shape, holding the cytoplasm, and controlling what moves in and out of the cell. It acts as a barrier, allowing certain substances to enter or exit while preventing others from doing so. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism, while the nuclear membrane surrounds the nucleus and controls the movement of materials in and out of it. However, neither of these structures specifically perform the functions mentioned in the question. Therefore, the correct answer is the cell membrane.

Jellylike material, most of the cell's chemical reactions take place here

Mitochondria
Cytoplasm
Chromosomes

Correct Answer

A. Cytoplasm

Explanation

The cytoplasm is a jelly-like material that fills the cell and is the site where most of the cell's chemical reactions occur. It contains various organelles, including mitochondria, which are responsible for energy production. The chromosomes, on the other hand, are located within the nucleus and contain the genetic material of the cell. Therefore, the correct answer is cytoplasm because it is where the majority of the cell's chemical reactions occur.

Digests food particles with enzymes

Nuclear pores
Ribosomes
Lysosomes

Correct Answer

A. Lysosomes

Explanation

Lysosomes are organelles found in cells that contain enzymes responsible for breaking down waste materials and cellular debris. They function as the cell's recycling centers, digesting food particles, old organelles, and foreign substances. Lysosomes fuse with the material to be digested and release their enzymes, which break down the particles into smaller molecules that can be reused by the cell. Therefore, lysosomes are involved in the digestion of food particles with enzymes.

Determines what traits a living thing will have

Chloroplasts
Centrioles
Chromosomes

Correct Answer

A. Chromosomes

Explanation

Chromosomes determine what traits a living thing will have. They carry the genetic information in the form of DNA, which contains the instructions for the development and functioning of an organism. The genes present on the chromosomes determine various traits, such as physical characteristics, behavior, and susceptibility to certain diseases. Chromosomes are found in the nucleus of cells and are passed on from parents to offspring during reproduction. They play a crucial role in inheritance and the transmission of genetic information from one generation to the next.

Liquid filles; may store food, water, minerals, or wastes

Nuclear membrane
Vacuoles
Mitochondria

Correct Answer

A. Vacuoles

Explanation

Vacuoles are responsible for storing various substances such as food, water, minerals, and wastes within a cell. They act as storage compartments that help regulate the cell's internal environment and maintain its overall structure and function. By storing these substances, vacuoles contribute to the cell's ability to maintain homeostasis and perform necessary metabolic processes.

8.

Secretes and stores secretions for transport out of the cell

Golgi apparatus (bodies)
Cytoplasm
Ribosomes

Correct Answer

A. Golgi apparatus (bodies)

Explanation

The Golgi apparatus is responsible for secreting and storing secretions for transport out of the cell. It processes and packages proteins and lipids into vesicles, which are then transported to the cell membrane for secretion. This organelle plays a crucial role in the sorting, modification, and packaging of molecules for secretion or delivery to other organelles within the cell. The cytoplasm is the fluid-filled region within the cell where various cellular processes occur. Ribosomes, on the other hand, are responsible for protein synthesis and are not directly involved in the secretion and storage of secretions.

9.

Produce energy when food is broken down

Endoplasmic reticulum
Mitochondria
Lysosomes

Correct Answer

A. Mitochondria

Explanation

Mitochondria are known as the powerhouses of the cell because they produce energy in the form of ATP through a process called cellular respiration. They break down food molecules and convert them into usable energy for the cell. This energy is essential for various cellular activities and functions. The endoplasmic reticulum and lysosomes have different roles within the cell, but they are not directly involved in the production of energy.

Found only in plat cells, gives the plant support and shape

Chloroplasts
Centrioles
Cell wall

Correct Answer

A. Cell wall

Explanation

The cell wall is a rigid structure that is found only in plant cells. It provides support and shape to the plant cell, helping it maintain its structure and prevent it from collapsing. The cell wall is composed of cellulose, a complex carbohydrate that gives it its strength and rigidity. It also acts as a protective barrier, preventing the entry of harmful substances into the cell. Chloroplasts are responsible for photosynthesis, while centrioles are found in animal cells and play a role in cell division.

Control the passage of molecules in and out of the nucleus

Nuclear pores
Chloroplasts
Nucleolus

Correct Answer

A. Nuclear pores

Explanation

Nuclear pores are responsible for controlling the passage of molecules in and out of the nucleus. These pores are large protein complexes that form channels in the nuclear envelope, allowing selective transport of molecules such as RNA and proteins. They play a crucial role in regulating gene expression and maintaining cellular homeostasis by ensuring the proper movement of molecules between the nucleus and the cytoplasm.

Encloses nucleus and controls what enters and leaves the nucleus

Nuclear pores
Nucleolus
Nuclear membrane

Correct Answer

A. Nuclear membrane

Explanation

The nuclear membrane encloses the nucleus and controls what enters and leaves the nucleus. It acts as a barrier, allowing only specific molecules to pass through the nuclear pores. This regulation is important for maintaining the integrity and functionality of the nucleus. The nuclear membrane also separates the genetic material within the nucleus from the rest of the cell, providing a protected environment for DNA replication, transcription, and other nuclear processes.

Found only in animal cells, used in reproduction to help chromosomes arranges before cell division

Centrioles
Vacuoles
Cell wall

Correct Answer

A. Centrioles

Explanation

Centrioles are cylindrical structures found only in animal cells. They play a crucial role in cell division by helping to organize and arrange chromosomes before the cell divides. They are responsible for forming the spindle fibers that attach to the chromosomes and pull them apart during cell division. Centrioles are not present in plant cells, making them unique to animal cells.

Makes ribosomes, found in the nucleus

Nucleolus
Ribosomes
Endoplasmic reticulum

Correct Answer

A. Nucleolus

Explanation

The nucleolus is responsible for making ribosomes, which are cellular structures involved in protein synthesis. It is located within the nucleus of the cell. The nucleolus contains the genetic material necessary for ribosome assembly and is involved in the production and maturation of ribosomal RNA (rRNA). Therefore, the nucleolus is the correct answer as it plays a crucial role in ribosome formation and is found within the nucleus.

The "transportation system" in the cell, connects the nuclear membrane to the cell membrane

Endoplasmic reticulum
Golgi apparatus
Nuclear pores

Correct Answer

A. Endoplasmic reticulum

Explanation

The endoplasmic reticulum is responsible for the transportation of materials within the cell. It is a network of membranes that extends from the nuclear membrane to the cell membrane. It plays a crucial role in protein synthesis, lipid metabolism, and the transport of molecules between different parts of the cell. Therefore, the endoplasmic reticulum is the correct answer as it is directly involved in the transportation system within the cell.
