What is Photosynthesis
What is the equation for photosynthesis
What function does glucose have
Carbon Dioxide + Water > Glucose + Oxygen
Photosynthesis is vital process that occurs in leaves of plants - leaves use chlorophyll and light
Glucose acts as food for plant
Explain function of following plant adaptations:
- Broad leaves
-
Thin leaves
- Xylem & Phloem
- Chloroplast
- Stomata
- Guard Cells
- Midrib
- Petiole-
- B-road leaves -large surface area to absorb as much sunlight as possible
- Thin leaves - provide short diffusion pathway for glasses to move in/out of cells
- Xylem/Phloem - transport water minerals ions and glucose around plant
- chloroplast contains green substance called chlorophyll which traps energy from sun for photosynthesis
- Stomata - tiny holes found mainly underneath leaf to allow gases to diffuse in/out of leaf. Each hole is a single Stoma
- Guard cells - control opening and closing of Stomata
- Midrib - provides strength throughout leaf keeping it upright and sturdy in wind
- Petiole - attaches leaf to stem
What are 4 main layers of a
Describe each
- Upper layer
Waxy layer protects from water loss, disease and weather - Palisade layer
Adapted to absorb a lot if light..had lots of chloroplasts . Shaped like tall box - Spongy layer
- Lower layer
How is water absorbed for photosynthesis
What is a root hair cell- describe structure
- through roots - have a type of cell called root hair cell
Projects into soil from root . Big surface area and thin walls which let water pass through easily . Normally in dark so do not contain chloroplasts and cannot carry out photosynthesis - transported through tubes in leaf
What’s main function if a leaf
Process for plant making glucose is called ?
Green pigment?
Which gas enters a leaf through the Stomata
What feature allows plants to absorb lots of sunlight
What product is released by photosynthesis
Make glucose
Photosynthesis
Chlorophyll
Carbon Dioxide
Large surface area
Oxygen
