WorksheetsPhotosynthesis Week 1
Total questions: 22
Worksheet time: 15mins
Why are plants usually green?
Because the chlorophyll reflects green light
Because the chlorophyll absorbs green light
Because the accessory pigments combine to make green
Because the accessory pigments only absorb green light
#1 - outermost layer and not made of cells; helps regulate water loss.
Epidermal cells
Palisade cells
Xylem cells
Waxy cuticle
#2 & #5 - outermost layer of cells; provides protection from outside elements.
Epidermal cells
Palisade cells
Phloem cells
Waxy cuticle
#3 - layer of tall, columnar cells that contain many chloroplast for photosynthesis
Epidermal cells
Guard cells
Pallisade mesophyll
Spongy mesophyll
#4 - layer of irregular cells with space in between the cells
Pallisade mesophyll
Phloem
Spongy mesophyll
Xylem
#6 - porous opening in the bottom of the leaf that allows for gaseous exchange
Pallisade mesophyll
Spongy mesophyll
Stomata
Vein
#7 - two cells that surround each porous opening; regulates gaseous exchange by opening and closing the pore.
Epidermal cells
Guard cells
Stomata cells
Xylem cells
#8 - Cell tissue that makes up part of each vein that transports glucose and nutrients throughout the plant
Epidermal cells
Guard cells
Phloem cells
Xylem cells
#9 - Cell tissue that makes up part of each vein that transports water throughout the plant
Epidermal cells
Guard cells
Phloem cells
Xylem cells
In which organelle does photosynthesis occur?
Cell Wall
Chlorophyll
Chloroplast
Cytoplasm
What are the round membrane disks inside the chloroplast where the light reactions take place?
Thylakoids
Cristae
Ribosomes
Cytoplasm
Match the following parts of the cell to their functions:
Green pigment that absorbs light energy
Chlorophyll
Space in the chloroplast where the Calvin Cycle occurs
Stroma
Membrane in the chloroplast where light reactions occur
Thylakoids
Organelle responsible for photosynthesis in plants
Chloroplast
Temperatures that are too high can slow photosynthesis because
stomata stay open
enzymes are ruined
there is not enough CO2
there is too much water
