Question

The cells making up the human body contain the same organelles as other animal cells. The diagram below shows the interior of a typical animal cell such as a muscle or fat cell. Each organelle has its own structure and function. Which description correctly differentiates between the structure and function of Organelle B? a This organelle contains chromosomes and proteins. Reactions inside it release energy that can be used for cell processes. b This organelle contains chromosomes and proteins. It directs cell activities and stores genetic information. c This organelle is composed of two membranes. Reactions inside it release energy that can be used for cell processes. dThis organelle is composed of two membranes. It directs cell activities and stores genetic information.

Answer 1

From the descriptions given, Organelle B could either be the nucleus or the mitochondrion. The nucleus contains chromosomes and proteins, directs cell activities, and stores genetic information while the mitochondrion is composed of two membranes and performs reactions that produce energy for cell processes.

Step-by-step explanation:

The option that correctly differentiates between the structure and function of organelle B depends on the specific organelles represented by B in the diagram, which is not provided. However, based on the given context, we can identify two main possible organelles: the nucleus or the mitochondrion-

1. Nucleus: If organelle B is the nucleus, the best fitting description would be: 'This organelle contains chromosomes and proteins. It directs cell activities and stores genetic information.' (option b). The nucleus is indeed the control center of a cell and holds the genetic information.
2. Mitochondrion: If organelle B is the mitochondrion, the description should be: 'This organelle is composed of two membranes. Reactions inside it release energy that can be used for cell processes.' (option c). The mitochondrion is the 'powerhouse' of a cell, producing energy through the process of cellular respiration.
