Exploring Cell Structure and Functions

What is the basic unit of life in all living organisms?

• Tissue

• Organ

• Cell

• Organism

Which part of the cell is responsible for producing energy?

• Nucleus

• Mitochondria

• Ribosome

• Cell Membrane

What is the primary function of ribosomes in a cell?

• Energy production

• Protein synthesis

• DNA replication

• Lipid storage

Which structure is found in plant cells but not in animal cells?

• Cell membrane

• Nucleus

• Chloroplast

• Ribosome

What is the main function of the cell membrane?

• To produce energy

• To control the movement of substances in and out of the cell

• To store genetic information

• To synthesize proteins

Explain why ribosomes are essential for cell function.

• They provide structural support to the cell

• They are involved in the synthesis of proteins, which are crucial for cell function

• They store energy for the cell

• They transport materials within the cell

Compare the roles of the cell membrane and the cell wall in plant cells.

• Both provide energy to the cell

• The cell membrane controls substance movement, while the cell wall provides structure and support

• Both store genetic information

• The cell wall controls substance movement, while the cell membrane provides structure

How does the presence of chloroplasts in plant cells affect their function compared to animal cells?

• Chloroplasts allow plant cells to perform photosynthesis, producing their own food

• Chloroplasts store water for the plant cell

• Chloroplasts provide structural support to the plant cell

• Chloroplasts are involved in protein synthesis

Analyze how the structure of the nucleus supports its function in the cell.

• Its porous membrane allows for the exchange of materials necessary for DNA replication and transcription

• Its solid structure prevents any material from entering or leaving

• Its small size allows it to move easily within the cell

• Its thick walls protect the DNA from damage

Evaluate the importance of the cell membrane's selective permeability.

• It allows all substances to enter and exit freely

• It prevents all substances from entering or exiting

• It allows the cell to maintain homeostasis by regulating the entry and exit of substances

• It stores genetic information
