Remembering 1 State the type of specialised plant cell that: a. Carries out photosynthesis Photosynthetic Cells b. Transports water and nutrients Conducting Cells c. Absorbs water from the soil Root hair cells d. Controls the opening and shutting of the holes, called stomata. Guard Cells Understanding 2 Define the term organelle. Small Organ L 3 Describe the function in the cell of: a. Its nucleus Is basically the control center it tells the cell what to do. b. Cell wall It gives the plant it’s rigidity. c. Chloroplasts. They absorb the sunlight needed for photosynthesis. 4 Explain the purpose of chlorophyll in a plant. It absorbs sunlight. Applying 5 Identify which type of specialised plant cell is: a. ‘Hairy’ Hair Root Cells b. The ‘gatekeeper’ Guard Cells c. A ‘transporter’. Conducting Cells 6 From the clues given, identify these substances found in a plant. Explain the function of each. a. I’m green. Chloroplasts b. I’m found in the cell wall. Cell Membrane c. I’m found in the vacuole. Sap 7 Photosynthesis is how green plants make their own food. Identify: a. The chemicals (reactants) the plant needs to carry out the reaction CO2, sunlight, water b. The chemicals (products) the reaction produces Glucose, Oxygen c. The name of the sugar that is used by plants as food Glucose d. From where the reaction gets its energy. Sunlight Evaluating 8 Propose what would happen to a plant without: a. Guard cells A large amount of water would be lost through the stomata b. Cellulose The plant would lose rigidity c. Chlorophyll. The plant would die 9 Propose a likely reason for each of the following: a. Most plants are green. Because the all have chloroplasts b. Plant cells have thicker walls than animal cells. To give them rigidity without bones. c. Photosynthetic cells are usually found only on the upper surface of a leaf. To get maximum light. d. There are two different types of conducting cells forming two different pathways in the plant. To transport water and food. 10 There are far more types of animal cells than plant cells. Propose a reason why. Because animals need muscles, nerves, blood, skin, bones etc. but plants don’t 11 Propose a reason why animals do not need to be able to carry out photosynthesis like plants do. Because we get our energy from eating animals and plants that already have energy inside them.
