Pinnately compound leaves have all of their leaflets attached at the same point at the end of the petiole II. Reticulate venation refers to the branching arrangement of veins in dicot leaves

1.  I. Pinnately compound leaves have all of their leaflets attached at the same point at the end of the petiole II. Reticulate venation refers to the branching arrangement of veins in dicot leaves

_____ 2.  I. Palisade parenchyma cells contain numerous chloroplasts, and make up the upper layer of the   mesophyll in leaves.

II. Bundle sheath cells are large, thin-walled cells that occur in the leaf epidermis near the central vein.

_____ 3.  I. Tendrils are modified stem tissue, which curl around rigid objects.

II. In autumn, the green chlorophyll pigments break down revealing pigments of other colors.

4.   I. Water is easily moved through living organisms because most cells have water pumps.

II.  An important function of plant parenchyma is to form a thick, hydrophobic layer on the surfaces of stems     and leaves which acts as an effective barrier to evaporation.

_____ 5.   I. Parenchyma typically lack a secondary wall and often function as storage depots. II. In primary roots, phloem is located in the center of the vascular cylinder.

_____ 6.   I. Transplantation of a plant is more successful if you take some of the surrounding soil with the plant                because the root hairs remain intact.

II. Roots are the only type of plant organ in the root system.

_____ 7.   I. All stem cells are living cells.

II. The wide portion of a foliage leaf is called the petiole.

_____ 8.   I. Some stems grow horizontally and are found underground.

II. The main function of adventitious roots is to anchor the plant.

_____ 9.   I. Mature nonwoody stems called herbaceous stems exhibit primary and secondary growth.

II. When a leaf has a blade composed of two or more leaflets, the leaf is called a compound leaf.

_____ 10. I. The fine lines present on the leaf are called ‘leaf veins’

                            II. The single middle prominent vein is known as ‘mid rib’ or the primary vein

_____ 11. I. A flowering plant consists of four parts, namely the roots, stems, leaves and flowers. II.  Compound leaves are divided into several leaflets.

_____ 12. I. In a flowering plant, the flowers contain the male and female reproductive organs.                II. The roots of a plant hold it erect.

_____ 13. I. The leaves of a plant take in water and mineral salts              II. The roots of a plant transpire water.

_____ 14.  I. A leaf with a single blade and petiole is considered to be simple.

 II. Netted venation appears as a network of smaller veins emanating from one or more larger veins. 

_____ 15.  I. Pinnately (netted) veined leaves have one major vein from which smaller veins diverge on either side.                 II. Palmately (netted) veined leaves have several main veins, each having many small branches.
