What do plants need for photosynthesis? Select all options that apply:

• Water

• Carbon dioxide

• Sunlight

• Glucose

What do plants make during photosynthesis? Select all that apply.

• Glucose

• Oxygen

• Carbon dioxide

• Water

Where do plants do photosynthesis?

• In their stems

• In their leaves

• In their roots

• In the soil

How do plants get carbon dioxide into their leaves?

• Via the roots

• Through stoma in the leaves

• Through the upper epidermis of the leaf

• Through the vascular bundle

How do plants get water into their leaves?

• Through their stoma

• Through the upper epidermis

• Through their roots then up the vascular bundle

• Through the palisade cells

What does the waxy cuticle do?

• Keeps water inside the cell

• Does lots of photosynthesis

• Lets water into the leaves

• Controls the opening/closing of stoma

What does the upper epidermis do?

• Keeps out bacteria and pests

• Lets water into the leaves

• Does photosynthesis

• Opens/closes the stoma

What do the palisade cells do?

• Some photosynthesis

• LOTS of photosynthesis

• Transports water into the leaf

• Opens/closes the stoma

What do the spongy mesophyl cells do?

• LOTS of photosynthesis

• Some photosynthesis and they have gaps between them to let gas (carbon dioxide and oxygen) move through the leaf

• Control entry of carbon dioxide into the leaf

• Transport water into the leaf

What does the xylem cells in the vascular bundle do?

• Transport water from the roots up into the leaves

• Transport glucose from the leaves down to the rest of the plant

• Control the entry of carbon dioxide into the leaf

• Control the exit of oxygen out of the leaf
