What are guard cells?

cells that surround the stoma to open and close the pore

are the main site of photosynthesis

How is a root hair cell adapted for its function?

It has a large surface area for absorption

carries water upward from the roots to every part of a plant

What is the primary function of a waxy cuticle?

Reduces water loss from the leaf

carries sugar and other nutrients from leaves to other tissues

tiny gaps in the epidermis of the leaf

A group of cells with a similar structure and function

The function of xylem tissue in a plant is to:

Carry water and minerals from the roots

Why do guard cells have chloroplasts?

To detect light and open the stomata in the day

What is translocation?

The movement of sugar through a plant in the phloem

How do guard cells open the stomata?

they fill with water to open the stomata

How does CO2 get to the palisade mesophyll?

Through the stomata from the air

Why are there air spaces in the spongy mesophyll?

it allows O2 and CO2 to move throughout the leaf

What does the meristem tissue do?

Creat new cells for the growth of the plants.

What is transpiration?

the loss of water from leaves by evaporation
