31

what is the cambium

is a thin layer of growing tissue that produces new cells that become either xylem phloem or more cambium

32

what is a xylem

it brings water and nutrients up from the roots to the leaves

33

what is the heart wood

it supports the tree and stores the dead xylem cells

34

what does perennial

35

what does conferrer does

there trees that have needle shaped leaves that stay green all year around
