4.3.1 Plant Cell Structure

• What are plant cells defined as in biology?

  Basic units of plants
• The cell wall of a plant cell is made of cellulose
• Chloroplasts are responsible for photosynthesis in plant cells.
• What is the primary function of the cell wall in a plant cell?

  Structural support and protection
• Chloroplasts perform photosynthesis to produce energy
• What does the vacuole in a plant cell store?

  Water, nutrients, and waste
• Match the plant cell component with its function:

  Chloroplasts ↔️ Conducts photosynthesis

  Vacuole ↔️ Stores water, nutrients, and waste
• Arrange the steps involved in the process of photosynthesis in chloroplasts:

  1️⃣ Absorption of light energy

  2️⃣ Conversion of light energy to chemical energy

  3️⃣ Fixation of carbon dioxide

  4️⃣ Production of glucose
• The cell wall provides structural support and protection
• Match the plant cell component with its function:

  Cell wall ↔️ Structural support and protection

  Cell membrane ↔️ Controls substance movement
• Vacuoles store water, nutrients, and waste in plant cells.
• What is the role of chloroplasts in plant cells?

  Photosynthesis
• Plant cells and animal cells share a cell membrane
• Plant cells have chloroplasts, while animal cells do not.
• What is a key similarity between plant and animal cells?

  Both have a cell membrane
• Plant cells have a cell wall, whereas animal cells do not.
• Plant cells contain chloroplasts, which are absent in animal cells
• How does the vacuole differ in size between plant and animal cells?

  Large and single in plants
• Chloroplasts are present in animal cells.

  False
• What are two key features that allow plant cells to perform photosynthesis and provide structural support?

  Cell wall and chloroplasts
• Plant cells can be rigid due to their cell walls
• Arrange the key components of a plant cell based on their primary function, starting with structural support:

  1️⃣ Cell Wall

  2️⃣ Cell Membrane

  3️⃣ Chloroplasts

  4️⃣ Vacuole
• Water stored in the vacuole is used by chloroplasts during photosynthesis.
• What material is the cell wall of plant cells made of?

  Cellulose
• Sclerenchyma cells provide rigidity due to their thick, lignified cell walls.
