Explanations: answer key for all 10 questions

Q1: What gives plant cells their rigid shape?
Answer: Cell wall
It is made mostly of cellulose.
Q2: Which organelle carries out photosynthesis?
Answer: Chloroplast
It contains green chlorophyll.
Q3: What does the large central vacuole store?
Answer: Water and dissolved substances
It helps keep the cell firm.
Q4: What is the pressure that keeps plant cells firm called?
Answer: Turgor pressure
Wilting happens when it drops.
Q5: What is cellulose?
Answer: A tough carbohydrate in cell walls
Paper and cotton are mostly cellulose.
Q6: Why are leaves green?
Answer: Chlorophyll reflects green light
Chlorophyll absorbs red and blue.
Q7: What tiny channels connect neighboring plant cells?
Answer: Plasmodesmata
They let molecules pass between cells.
Q8: Do plant cells have mitochondria?
Answer: Yes
They release energy from sugars.
Q9: What happens to a plant cell in very salty water?
Answer: It loses water and shrinks
This is called plasmolysis.
Q10: Chloroplasts are believed to have come from what?
Answer: Ancient cyanobacteria
They have their own DNA.

Plant Cells Knowledge Quiz – What Makes Plant Cells Special

Plant cells share many features with animal cells, including a nucleus, cell membrane, mitochondria and ribosomes. But they also have structures animals lack: a rigid cell wall, chloroplasts and a large central vacuole.

The cell wall, made mainly of cellulose, gives plants strength and shape. Chloroplasts capture sunlight and turn it into sugar through photosynthesis. The vacuole stores water and pushes against the wall, keeping plants firm through turgor pressure.

Plant cells connect through tiny channels called plasmodesmata, letting them share water and nutrients. These special features let plants stand tall, make their own food and support nearly all life on Earth.
