axil - the angle between the upper side of the stem and a leaf, branch, or petiole. axillary bud - a bud that develops in the axil. flower - the reproductive unit of angiosperms. flower stalk - the structure that supports the flower. internode - the area of the stem between any two adjacent nodes. lateral shoot (branch) - an offshoot of the stem of a plant. leaf - an outgrowth of a plant that grows from a node in the stem. Most leaves are flat and contain chloroplasts; their main function is to convert energy from sunlight into chemical energy (food) through photosynthesis. node - the part of the stem of a plant from which a leaf, branch, or aerial root grows; each plant has many nodes. Label the two lower nodes (the first and second nodes) on the plant diagram. |
petiole - a leaf stalk; it attaches the leaf to the plant. root - a root is a plant structure that obtains food and water from the soil, stores energy, and provides support for the plant. Most roots grow underground. root cap - a structure at the ends (tips) of the roots. It covers and protects the apical meristem (the actively growing region) of the root. stem - (also called the axis) is the main support of the plant. tap root - the main root of some plants; the tap root extends straight down under the plant. terminal bud - a bud located at the apex (tip) of the stem. Terminal buds have special tissue, called apical meristem, consisting of cells that can divide indefinitely. |
