Monocots Monocot plants are one of the two major botanical classes of flowering plants‚ or angiosperms. The other class includes the dicot flowering plants. These fundamental classes were given formal taxonomic standing by botanists in the mid-17th century‚ replacing previous plant classification systems that were based on growth form. Roughly one-fourth of all flowering plant species are monocots‚ including a number of species important to humans as food plants or ornamentals Distinct Flowers

Biology Lab Comparing and Contrasting Monocots and Dicots Question: In this Investigation‚ live plant specimens of flowering plants would be used to classify plants as monocots or dicots. Hypothesis: Monocots have one embryonic seed leave while Dicots have two. Monocots have one cotyledon in seed while dicots have two. Xylems and Phloem are in circular shape in dicots‚ while monocots’ are scattered. Monocots have the multiples of 3 petals while dicots can have 4/5 petals. Monocots have parallel

DICOT STEM Plants showing anomalous secondary growth can be studied in two main groups. (1) Those in which cambium of normal type is present and persists but by peculiarity or irregularity in its activity develop vascular tissues of unusual arrangement. (2) Those in which the normal cambium either does not develop or in soon replaced by another cambium. This abnormal cambium may either develop from cortex or pericycle and shows abnormal activity. NORMAL CAMBIUM WITH ABNORMAL ACTIVITY: Aristolochia

Ryan Tudino Mrs. Couchon Biology Honors/ 1A 10 April 2013 Abstract The seeds of summer squash (Cacurbita moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic

Monocots and eudicots share features that define each as an angiosperm. At the cellular level‚ the two have similar structures and functions. Yet‚ as the cells differentiate and form into tissues and organ systems‚ there are structural and organizational differences that can be used to discern the two. These differences and modifications can be evolutionarily beneficial to the plant‚ and can also make the plant more desirable for human use. To begin‚ both monocots and eudicots have primary meristems

Aim: To investigate and compare the distribution density of stomata in the upper and lower epidermis of a dicotyledonous leaf. Stomata are the principle means of gas exchange in plants. Stomata are small pores they are controlled by guard cells which control the opening and closing of stomata. Stomata allow carbon dioxide to enter the plant‚ and allow water and excess oxygen to escape. About 90% of water is lost from the leaf during transpiration. The number of stomata on leaf surface varies among

THE EFFECT OF LIGHT INTENSITY DURING PLANT GROWTH ON THE SIZE OF STOMATA IN DICOT LEAVES Christina Durgan Nicole Romero Vanessa Chilunda Biology 101‚ Thursday 1:15pm Claire Burkum 5 December‚ 2013 1. The hypothesis of this study is that the size of the stomata on the dicot leaves exposed to higher light intensity will be smaller compared to the size of the stomata on the dicot leaves exposed to lower light intensity. This is because at higher light intensity there is an increase in environmental

Exercise 5: Gymnosperms and Angiosperms ______________________________________________________________________________ OBJECTIVES: 1. Describe the distinguishing features of gymnosperms and angiosperms. 2. Understand the evolutionary significance of pollen and seeds. 3. Understand the function of a cone‚ a flower‚ and a seed. 4. Relate the life cycle of angiosperms to the other phyla of the plant kingdom. ______________________________________________________________________________ INTRODUCTION

(Dagne and Yenesaw 1994). However‚ there is still not strong enough evidence suggesting both sub-families should not be included in a single family‚ the Asphodelaceae (Bisrata 2000). MORPHOLOGY Asphodelaceae is a distinct family from other liliod monocot groups by a combination of several morphological and reproductive features: simultaneous microsporogensis‚ atypical ovular structure‚ lacking steroidal saponins‚ producing seeds with arils‚ and the general presence of anthraquinones.
