Table 9.6.0 Monocotyledons and dicotyledonġ. buttercup, wallflower, groundsel.ĩ.2 Monocotyledons and dicotyledons, (angiosperms) Inflorescences, clusters of flowers, can be produced from axillary or terminal buds.Įxamine the external features of a herbaceous flowering plant, e.g. The nodes and young leaves are telescoped together.Įlongation of the short internodes in this region results in growth in length of the shoot.Īxillary buds in the axils of leaves are also embryonic shoot systems that can grow into lateral branches, stems bearing leaves, or they may just remain dormant. This reticulate venation is typical of dicotyledons.Īt the apex of the shoot is the terminal bud with the growing point protected and covered by young unexpanded leaves. The leaf venation, pattern of veins, is net-like. The petiole, leaf stalk, joins the leaf base to the expanded lamina, the leaf blade. The leaf is attached to the stem by a leaf base. The internode is the part of the stem between two nodes. The leaves are attached to the stem at the nodes.
* The shoot system consists of stem, leaves and buds. * Phloem tissue consisting of sieve tubes and companion cells for the transport of nutrients and hormones. * Stamens with pollen sacs produce pollen. * Double fertilization produces a zygote that becomes the embryo plant and endosperm nutritive tissue in the seed for the developing plant embryo. The three parts together are called the pistil. The carpel with three parts, the stigma where pollen germinates, the style that allows pollen tubes to reach the ovary, and an ovary that encloses the ovules and where fertilization occurs. Angiosperms have the following characteristics: Nowadays the term "angiosperm" is not used in plant classification.ġ. Tracheophyta (vascular plants), monocotyledons and dicotyledonsĪngiosperms, have seeds enclosed in an ovary, they are the "flowering plants".Īngiosperms have endosperm inside the seeds which are enclosed in a fruit.
