1.2 Cell Function

• Cells carry out life processes such as respiration, photosynthesis, transport, and reproduction
• Ribosomes are small structures where protein synthesis
• The nucleus contains the cell's genetic material and controls its activities.

  True
• Match the process with its description:

  Energy Production ↔️ Glucose breakdown, ATP synthesis

  Waste Removal ↔️ Diffusion, active transport
• Glucose is broken down to release energy
• What metabolic waste products are removed during excretion?

  Carbon dioxide, nitrogenous waste, excess water
• Steps of energy production in cells:

  1️⃣ Glucose breakdown

  2️⃣ ATP synthesis
• What is the benefit of energy production to the cell?

  Provides energy for activities
• Endocrine signaling uses hormones to travel to distant target cells.
• Cellular function depends on cell type and organelles.
• What do lysosomes break down in the cell?

  Waste materials
• What metabolic waste products are eliminated during excretion?

  Carbon dioxide, nitrogenous waste, excess water
• Waste removal in cells involves the process of excretion
• Why is cell communication essential for multicellular organisms?

  Coordinates cellular activities
• What is the first step in a cell signaling pathway?

  Signal production
• Meiosis produces four daughter cells that are genetically distinct
• Eukaryotic cells contain membrane-bound organelles
• Match the organelle with its function:

  Chloroplasts ↔️ Site of photosynthesis

  Endoplasmic Reticulum ↔️ Transports materials

  Golgi Apparatus ↔️ Packages proteins

  Ribosomes ↔️ Protein synthesis
• The cell membrane controls what enters and leaves the cell and provides structural support
• Cellular respiration occurs in the mitochondria
• Cell signaling is a main mechanism of cell communication.


  True
• Waste removal in cells is also known as excretion
• Match the cellular process with its location:

  Energy Production ↔️ Mitochondria

  Waste Removal ↔️ Cell membrane
• Cell communication is essential for coordinating cellular activities
• What happens in paracrine signaling?

  Signaling molecules act on nearby cells
• What is autocrine signaling?

  A cell secretes molecules that bind to its own receptors
• Cell signaling allows cells to respond to environmental changes.


  True
• Match the organelle with its function:

  Chloroplasts ↔️ Photosynthesis

  Endoplasmic Reticulum ↔️ Protein synthesis and transport

  Golgi Apparatus ↔️ Protein packaging and distribution

  Ribosomes ↔️ Protein synthesis
• Cellular respiration releases energy in the form of ATP.


  True
• What is the main process for energy production in cells?

  Cellular respiration
• The cell membrane is involved in waste removal through diffusion and active transport


  True
• Endocrine signaling involves the release of hormones into the bloodstream


  True
• What is the primary outcome of mitosis?

  Two identical daughter cells
• What distinguishes prokaryotic cells from eukaryotic cells in terms of their nucleus?

  No true nucleus
• Match the cell type with its example:

  Prokaryotic cell ↔️ Bacteria

  Eukaryotic cell ↔️ Animal cell
• Mitochondria are the site of cellular respiration where energy is released from food molecules.


  True
• Lysosomes contain digestive enzymes that break down waste materials and worn-out organelles.


  True
• Order the steps involved in cellular energy production:

  1️⃣ Glucose is broken down

  2️⃣ Energy is released

  3️⃣ ATP is synthesized
• Cell communication is essential for coordinating cellular activities
• Energy release in cells occurs in the mitochondria.
