1.1 Cell Structure

• Growth in cells refers only to an increase in their size.

  False
• The cytoplasm is a gel-like substance where chemical reactions occur.
• Chloroplasts are found in plant cells and are the site of photosynthesis.
• Ribosomes are the site of protein synthesis in all cells.


  True
• Where does photosynthesis occur in plant cells?

  Chloroplasts
• The cell membrane is composed of a phospholipid bilayer
• A cell is the basic structural and functional unit of all living organisms
• The cytoplasm is a gel-like substance where chemical reactions occur.


  True
• The cell membrane is composed of a phospholipid bilayer
• Mitochondria produce energy in the form of ATP
• Mitochondria produce ATP through cellular respiration
• The cell membrane provides structural support to the cell.


  True
• What genetic material does the nucleus store?

  DNA
• Mitochondria are often referred to as the "powerhouses" of the cell.

  True
• What material is the cell wall of plant cells made of?

  Cellulose
• What is the role of the cell wall in plant cells?

  Structural support
• Metabolism within a cell provides energy for cellular activities.


  True
• Match the cell function with its description:

  Metabolism ↔️ All chemical processes within the cell

  Reproduction ↔️ Creating new cells or organisms

  Structure ↔️ Physical organization of cell components
• The nucleus contains DNA and controls cell activities.


  True
• Steps in protein processing in a eukaryotic cell:

  1️⃣ Protein synthesis begins in the endoplasmic reticulum

  2️⃣ The Golgi apparatus packages the protein

  3️⃣ The protein is transported to its final destination
• The gel-like substance in a cell where chemical reactions occur is called cytoplasm
• Match the cell component with its function:

  Endoplasmic Reticulum ↔️ Protein synthesis

  Golgi Apparatus ↔️ Packages and distributes proteins
• What is the primary role of the nucleus in a cell?

  Controls cell activities
• Arrange the functions of a cell in a logical sequence:

  1️⃣ Reproduction

  2️⃣ Growth

  3️⃣ Response to Environment

  4️⃣ Metabolism
• The cell membrane surrounds the cell and controls the movement of substances
• The cell membrane is a thin, flexible barrier.


  True
• The nucleus is often referred to as the "brain" of the cell


  True
• Match the eukaryotic cell components with their functions:

  Cell Membrane ↔️ Controls substance movement

  Nucleus ↔️ Stores genetic material

  Mitochondria ↔️ Produces energy for the cell

  Ribosomes ↔️ Site of protein synthesis
• Arrange the following steps of protein synthesis in the correct order:

  1️⃣ DNA is transcribed into mRNA

  2️⃣ mRNA moves to the ribosome

  3️⃣ Ribosome translates mRNA into a polypeptide chain

  4️⃣ Polypeptide chain folds into a protein
• The cell membrane is composed of a phospholipid bilayer
• The nucleus controls cell activities such as metabolism, growth, and reproduction
• What is the primary function of ribosomes?

  Protein synthesis
• Chloroplasts are found in animal cells.

  False
• A cell is the basic structural and functional unit of all living organisms
• What is a eukaryotic cell the basic structural and functional unit of life in organisms like plants, animals, and fungi?

  Eukaryotic cell
• Mitochondria produce ATP for the cell through cellular respiration


  True
• What does the Golgi apparatus do in the cell?

  Packages and distributes proteins
• The cell membrane is selectively permeable, allowing only certain substances to pass through


  True
• Mitochondria are often referred to as the "powerhouses" of the cell

  True
• Chloroplasts in plant cells are the site of photosynthesis
