Introduction An angiosperm (flowering plant) can either be monocotyledonous (a monocot) or dicotyledonous (a dicot) according to the number of embryonic seed leaves (cotyledons) in the seed. In the case of a monocot‚ there is only one photosynthetic cotyledon present in the seed‚ and in the case of a dicot‚ there are two photosynthetic cotyledons present in the seed‚ hence the name. The cotyledons of a dicot may also emerge and show above the ground when the seed germinates. This assignment

PRACTICAL 6 Seed Plants (Gymnosperms and Angiosperms) OBJECTIVES: 1. To describe the features of seed plant life cycle and the concept of the dominant generation. 2. To describe the life histories and related reproductive structures of gymnosperms and angiosperms. 3. To summarize the features that distinguish gymnosperms and angiosperms. 4. To discuss the advantages of seed plants to dominate land and their evolutionary adaptations on land. EXPERIMENT 1: Gymnosperms INTRODUCTION: Gymnosperms

9.1.2 3 difference between monocots and dicots 3 differences between monocots and dicots 1. Monocots have parallel venations along their leaf 2. Dicot roots have X-shaped xylem whereas monocots are organized into a ring 3. Dicot stem xylem form a ring around the outside whereas monocot xylems are scattered 9.1.3 Distribution of tissues in leaves and functions In the leaf you have xylem and phloem tissues. Xylem tissues act like transport tubes‚ transporting water and minerals. Phloem tissues

3. How many stamens does this flower have? I see about 3. 4. 5. How many stigmas does this flower have? I can see about 6 or 7 stigmas. 6. 7. Is this the flower of a monocot or a dicot? A monocot. 8. 9. Explain your answer for question #4. Monocots have veins that are almost always aligned parallel to each other. A monocot will also grow in pairs of three leaves. 10. Is this flower perfect or imperfect? Perfect. This is because a Lillie flower has both male and female parts‚ the stamens and

tissues of dicot stems. These are the extension of xylem parenchyma cells into the vessel elements(NEET-II 2016). Cortex tissue is present in between the epidermis and stele. It is multilayered and is made up of parenchymatous cells with big intercellular spaces (NEET-II 2016). Wood of gymnosperms does not contain vessels.e.g- Pinus is vesseless. Vessels are the characteristic feature of angiosperms (AMU 2015). Protoxylem is the major anatomical structural difference which distinguishes dicot stem from

you suppose is the primary function of the cortex? storage of starch b. Do secondary roots arise inside the primary root or on its surface? from inside c. How does the structure of a monocot root differ from that of a dicot? Dicot roots have a central stele surrounded by a thick cortex and epidermis. Monocot roots have a vascular cylinder of xylem and phloem that surrounds a central pith. 5. a. Where is the starch located in carrot root? cortex b. What can you conclude from this observation

INTRODUCTION The roots of most plants are found underground although there are plants that have their roots suspended in the air as in orchids. The entire mass of roots is called the root system. The root arises from the radical which later becomes the primary root. Branches that develop from the primary roots are called secondary roots are the tertiary roots. The

flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon)‚ and pollen grains with a single groove while eudicots (true dicots) have two cotyledons‚ and pollen grains with three groove. Monocotyledons have leaf lamina with parallel vein. Their sepal‚ petal arranged in a series of 3s with adventitious root

EXERCISE 5 PHYTOGRAPHY: THE FRUIT Name: JOHN REY CORPUZ Score: Date:APRIL 2‚ 2013 Section: I. INTRODUCTION The fruit is a matured ovary containing one or more seeds. It is composed of the exocarp‚ mesocarp and the endocarp. Many floral parts aside from the ovary are persistent and therefore could still be seen in mature fruits. Some examples are the receptacles (apple‚ sepals (eggplant)‚ style (corn) and many more. There are several variations of the
