http://www.ucmp.berkeley.edu/IB181/VPL/Ana/Ana1.html
The morphology and anatomy of fossil plants contains a wealth of information on the function, physiology, ecology, and life habit of ancient plants. Plant morphology can also yield clues to taxonomic and evolutionary relationships. Consequently, background in plant structure is a prerequisite for studying land plant evolution. This lab reviews plant structure, especially cell and tissue types, and the arrangement of the vascular system. We provide only the most basic information here.

Basic Organization
Compared with animals, plants have a relatively simple design. Most land plants consist of a stem or axis , which functions for support and contains the conducting tissues of the plant. The stem usually supports light-gathering and photosynthetic structures called

  • The anatomy of a plant is shaped by cell walls that give the plant its structural framework. Studying the framework of the plant will help you understand how it is organized and grows. The illustrations on this page show details of duckweed anatomy that cannot be seen by casual observation. The first two sections have diagrams illustrating the relationships among the fronds in a typical cluster. To understand these diagrams it is important to keep in mind that the duckweed plants consists of a cluster of fronds descended from a single mother frond. You can view the hidden framework inside a duckweed plant using a simple chemical treatment. Read how.

Exercises in morphology and functional anatomy of spermatophytes (compulsory basic course, 1st semester)
In a number of sessions, basic functional anatomy of the seed plants is taught through an introductory lecture and associated practical exercises. Each session is concluded by a plenary discussion. The general focus is on the relationship between structure and function in plants. The sessions include the following themes: a. Construction and use of the microscope, cell structure. Procedures for staining cell organelles, cells and tissues. pH and osmolarity of cells. b. Structure and functions of membranes. Structure and functions of the cell wall. The cell as an osmotic system. Plasmolysis and experiments on osmotic events using tissues, isolated cells and protoplasts. c. Germination and growth. The life cycle of the plant. Embryonic and seed development. Mobilisation of the reserve materials of the seed and the enzymatic breakdown processes involved. Growth and development of monocot and dicot seedlings. d. The root. Root ontogeny. Vertical zonation and horizontal differentiation. Functional analysis of the calyptra and the respective rootzones. Structure-function relationships of various cells and tissues. Gravitropism, water and mineral uptake, selection by the endodermis. Apoplast, symplast. Root hairs and hair roots. Vascular bundles, xylem and phloem.

BOTONY AT A GLANCE
Knowledge of the fine structure of plant cells has enabled investigators to determine the sites of important biochemical activities, especially those involved in the transfer of energy during photosynthesis and respiration. The scanning electron microscope, a relatively recent development, provides a three-dimensional image of surface structures at very great magnifications. For experimental research on the morphogenesis of plants, isolated organs in their embryonic stage, clumps of cells, or even individual cells are grown. One of the most interesting techniques developed thus far permits the growing of plant tissue of higher plants as single cells; aeration and continuous agitation keep the cells suspended in the liquid culture medium.

The course of study for a major in Biology seeks to provide students with a sound introduction to the fundamental principles of biology, and to enhance their understanding and appreciation of the diversity and complexity of living things. The Department of Biology offers courses that prepare students for graduate study in biology, as teachers of biology, as biologists in governmental and industrial employment, and for advanced professional courses in medicine, dentistry, nursing, physical therapy, and medical technology.
Courses leading to the Bachelor of Arts (B.A.) and to the Bachelor of Science (B.S.) degrees in Biology are available. Required biology courses are identified for both programs, but the B.A. requires the additional courses detailed elsewhere under Additional Requirements for the Bachelor of Arts.

Monocot seeds have one "seed leaf" termed a cotyledon (in fact monocot is a shortening of monocotyledon). Dicots have two cotyledons.

The cell is the basic unit of life. Plant cells (unlike animal cells) are surrounded by a thick, rigid cell wall. The following is a glossary of plant cell anatomy terms. amyloplast - an organelle in some plant cells that stores starch. Amyloplasts are found in starchy plants like tubers and fruits. ATP - ATP is short for adenosine triphosphate; it is a high-energy molecule used for energy storage by organisms. In plant cells , ATP is produced in the cristae of mitochondria and chloroplasts cell membrane - the thin layer of protein and fat that surrounds the cell, but is inside the cell wall. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others. cell wall - a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.

OVERVIEW: DEVELOPMENTAL PLANT ANATOMY
INTRODUCTION Developmental plant anatomy must include studies that focus on key aspects of plant structure-function relationships. The material that is presented in the 'Factfiles' supplements that which can be found in Applied Plant Anatomy , and students are encouraged to cross-refer and to make use of The Anatomy of Seed Plants and Plant Anatomy by Esau as well as any other plant anatomy reference texts that are available. The material covered in the Factfiles includes leaf development, the development of the vascular system, intercellular transport, phloem loading and unloading. Interest will be focused on the leaf and specifically, development of the xylem and phloem. Biochemically, plants may function as sources and sinks - with sources being the sites at which essential carbon skeletons are synthesized and sinks being those regions where these carbon skeletons are either accumulated (stored) or metabolized and converted into other more useful secondary plant metabolites associated either with growth or further development of the plant. Take for the potato tuber as an example. The tuber acts as a strong carbohydrate sink in the summer season, attracting excess carbohydrates which are converted into starch. Once the potato plant has died, the tuber will undergo a series of complex changes, related to the onset and formation of "eyes" (root primordia). This occurs particularly in relation to its transport physiology, with the result that the tuber becomes a
