Which of the following organelles is involved in protein synthesis?

Endoplasmic reticulum
Golgi apparatus
Mitochondria
Chloroplasts
Lysosomes

Correct Answer

A. Endoplasmic reticulum

Explanation

The endoplasmic reticulum is involved in protein synthesis. It is a network of membrane-bound tubes and sacs located in the cytoplasm of eukaryotic cells. The rough endoplasmic reticulum (RER) is studded with ribosomes, which are responsible for protein synthesis. The ribosomes on the RER synthesize proteins that are destined for secretion or for incorporation into the cell membrane. These proteins are then transported within the endoplasmic reticulum to undergo further modifications before being transported to their final destinations within the cell or outside of it.

All of the following are present in animal cells EXCEPT_______.

Cell membrane
Chloroplasts
Centrioles
Vacuoles
Mitochodrion

Correct Answer

A. Chloroplasts

Explanation

Animal cells do not have chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. Animal cells do not perform photosynthesis, so they do not have chloroplasts.

Which of the following structures is responsible for capturing light to enable plants to produce their own food?

Mitochondrion
Vacuole
Chloroplast
Lysosome
Golgi apparatus

Correct Answer

A. Chloroplast

Explanation

Chloroplasts are responsible for capturing light to enable plants to produce their own food through the process of photosynthesis. This organelle contains chlorophyll, a pigment that absorbs light energy, and other necessary components for photosynthesis to occur.

Which of the following specialized cells are responsible for sending impulses to the different parts of the body?

Red blood cells
Liver cells
Muscle cells
Nerve cells
Skin cells

Correct Answer

A. Nerve cells

Explanation

Nerve cells, also known as neurons, are specialized cells responsible for sending impulses or signals to different parts of the body. These cells have a unique structure that allows them to transmit electrical signals, known as action potentials, along their length. Nerve cells are found throughout the body and are essential for the proper functioning of the nervous system. They play a crucial role in transmitting sensory information, coordinating muscle movements, and regulating bodily functions. Unlike other cell types listed, such as red blood cells, liver cells, muscle cells, and skin cells, nerve cells are specifically adapted for the transmission of electrical impulses.

Which of the following cell parts has NO double membrane?

Mitochondria
Nucleus
Plastids
Lysosomes
Endoplasmic reticulum

Correct Answer

A. Lysosomes

Explanation

Lysosomes do not have a double membrane. They are single-membrane organelles that contain digestive enzymes. These enzymes help break down waste materials, cellular debris, and foreign substances. Unlike other organelles such as mitochondria, nucleus, plastids, and endoplasmic reticulum, lysosomes have only one membrane surrounding them. This single membrane allows the enzymes within the lysosomes to interact with the substances they need to break down.
