The cross-sections demonstrated the basic differences that distinguish a monocot plant for a dicot plant. When looking at the cross-section of the monocot stem you can see that the vascular bundles are scattered. These vascular bundles consist of only a phloem and xylem. The phloem is responsible for transporting soluble compounds (food) created by photosynthesis, to the rest of the plant, especially where they are needed. The xylem is important for the movement of water throughout the plant. Another difference that can be seen by looking at the cross-section of at stem is that the ground tissue (parenchyma) is not partitioned into pith and cortex. In the dicot stem cross-section the vascular bundles form a ring and they are made up of a phloem, xylem, and a cambium which divides the two. The ground tissue (parenchyma) for a dicot is separate into a pith (nutrient storage and distribution) and a cortex (conducting tissues). The Leaf cross-sections reveal the venation of each plant. For monocots, the veins appeared run parallel to each other, while the veins for the dicot plant had no clear pattern. The root cross-sections also displayed differences between the groups belonging to the phylum Anthophyta. The root cross-section of a monocot is formed by vascular bundles that are arrange in a ring. In the dicot root cross-section, the xylem is at the center in the form of an

Classify plants and animals according to the physical characteristics that they share. Identify the structures in plants (leaves, roots, flowers, stem, bark, wood) that are responsible for food production, support, water transport, reproduction, growth, and protection.

Chloroplast: An organelle bounded by a double membrane containing the enzymes and pigments that perform

Second off we have the plant cell. The plant cell has chloroplasts unlike a animal cell (Doc.1). Chloroplasts hold

Tubers are similar to roots, they store energy for the new plant, and helps with vegetative

Like animals, plants are affected by gravity. Yet, they manage to grow upward and to great heights. How do they do this? While there are many forces acting on plants from the outside, there are also forces at work within plants themselves. These forces enable plants to stay up straight, take in water, extend their roots, and find light. Plants hold themselves up in two main ways, through turgor pressure and by using special woody tissues.

5. Roots in and out of water. Leaves might need to excrete salt or waste. Won’t rot or mold.

Tell kids you are looking for descriptive words for the plants like: sticky, pointy, rough, soft, smooth, fuzzy.

They receive water through the roots through

There are three reasons why plants grow because because of water and photosynthesis. To begin with, palisides are are the cells that contain chloroplasts. Palisides are found under a leaf because chloroplast are sticky and sinks through the leaf and sticks and stays under the leaf. Additionally, glucose is a sugar that plants create to feed themselves. If the plant doesn’t have sunlight, soil, and water, the plant can’t form glucose. Next, chloroplasts is a plastid in the cell that forms glucose through photosynthesis. Chloroplasts forms glucose so the plant can eat. As a result, plants can grow in many different ways if it has water and can do photosynthesis.

How do plants grow? “The internodes in the terminal bud are very short so that the developing leaves grow above the apical meristem that produced and thus protecting it.”(“Stem Growth”) If leaves do not form the plant cannot create glucose for food. Terminal bud produces cells that enable the stem to grow longer, and periodically which give rise

to have thick bark , deep roots , and waxy coatings on leaves. Plants in the savannas adapt to grow

Unlike most other plants, it does not have roots, leaves, or stems. It does contain a colouring called chlorophyll which is needed by all plants to turn sunlight into energy.

Plants are classified as living things due to having the characteristics of life. The first of which being growth, a plant has a life cycle and grows from a seed to a mature plant and eventually die (Cambridge University , 2005).

For centuries up until the present day, plants have given us so many things to our society. They can be used as food to give energy or to give cure for some illnesses. It has so many uses which is important for our daily living.
