What part of the plant anchors it into the ground?

• roots

• stem

• flowers

• leaves

What part of the plant is the main site of photosynthesis?

• roots

• stem

• flower

• leaves

Why are the upper epidermis cells transparent (see through)?

• so light can get to the lower tissues for photosynthesis

• so more light can be absorbed

• to prevent water being lost

What are the names of the holes on the underside of the leaf that allow gases to move in and out of the leaf?

• stomata

• waxy cuticle

• upper epidermis

• guard cells

What do the palisade cells have lots of that allows lots of photosynthesis to happen in them?

• chloroplasts

• ribosomes

• cytoplasm

• nucleus

Why do plants need a waxy cuticle?

• allows for lots of photosynthesis

• prevents water loss

• allows gases to enter and leave the leaves

In what part of the cell does photosynthesis occur?

• ribosomes

• nucleus

• chloroplasts

• cytoplasm

What does the xylem transport around the plant?

• sugars

• water and minerals

What does the phloem transport around the plant?

• sugars

• water and minerals

What are the cells around the stomata called?

• spongy mesophyll

• palisade cells

• guard cells
