plant science

what is the epidermis made of

• collenchyma cells

• parenchyma cells

• sclerenchyma cells

tissue between upper and lower epidermis

• mesophyll

• xylem

• phloem

• veins

vascular bundles of xylem and phloem are what

• guard cells

• parenchyma

• epidermis

• veins

this regulates whether gases can enter/leave the plant through the stomata

• guard cells

• veins

• palisade mesophyll

• spongy mesophyll

the openings in the epidermis layer that allow for gas exchange

• veins

• chloroplasts

• stomata

• phloem

what is the bundle sheath made of

• sclerenchyma

• chlorophyll

• parenchyma or sclerenchyma cells

• collenchyma cells

where are stomata typically located

• lower epidermis

• all throughout the epidermis

• upper epidermis

• middle epidermis

this allows CO2 to enter the plant for photosynthesis

• mitochondria

• mesophyll

• chlorophyll

• stomata

the main site of photosynthesis between the upper and lower epidermis

• palisade mesophyll

• spongy mesophyll

the main site for gas diffusion between the lower and upper epidermis

• spongy mesophyll

• palisade mesophyll
