Topic 9: Plant Science 9.1 Plant Structure and Growth 9.1.1 Draw and label plan diagrams to show the distribution of tissues in the stem and leaf of a dicotyledonous plant. Cross-section of a stem Part of plant | Purpose | Epidermis | Surface of the stem made of a number of layers often with a waxy cuticle to reduce water loss | Cortex Tissue | Forming a cylinder of tissue around the outer edge of the stem. Often contains cells with secondary thickening in the cell walls which provides

TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season

Plant Adaptation Investigation Observations Samples of plants were obtained during the campus tour. In order survive in the harsh climate of deserts‚ plants must adapt in function‚ reproduction‚ support‚ and defense. Although plants on campus are watered frequently‚ they live in a mostly xeric environment. Three types of cacti were observed: organ pipe‚ prickly pear‚ and saguaro. The organ pipe contains no leaves and has narrow stems that carry out photosynthesis and store water. Neither the

The uses of plants in developing and producing vaccines For thousands of years‚ society has been brought to the brink of disaster thanks to the spread of resilient diseases and the plague of hardy viruses. However‚ humans have been aware for just as long of medicinal defence mechanisms against these ailments. The ancient Egyptians and Romans‚ as well as the primitive islander and Aboriginal communities‚ knew that certain herbaceous matter could help heal the wounded and sick. In more recent times

PLANT LAYOUT Plant layout is a plan of the most effective arrangement of the physical facilities and manpower for the manufacture of the product. Plant layout encompasses much more than the mere planning of the arrangement of the production equipment and should include a careful study of the following: 1. External transportation facilities. 2. Receiving operations (unloading‚ inspection‚ stores) 3. Production activities. 4. Service & auxiliary operations.

Plant Hemoglobin Hemoglobin is a protein-iron compound found within the red blood cells of most vertebrates and is responsible for the cell’s red pigment. These red blood cells carries oxygen from the lungs to the rest of the tissue cells throughout the rest of the body. Just as hemoglobin transports oxygen in humans‚ they have also been found transporting oxygen within plants. In plants‚ there are two types of hemoglobin that can be found; symbiotic and non symbiotic. Oxygen is used

Fast Plants By: Kinser Haselhuhn Biology 111 Section Y Professor Brittingham 4/19/13 Abstract: Introduction: Materials and Methods: To begin the fast plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant

“The Private Life of Plants: Traveling” was a useful documentary to help clarify my understanding on how plants manage to spread their seeds and germinate. I enjoyed watching the different time lapses for the species of plants and it helped me to see exactly what happens rather than reading it in a book or seeing a simple picture. I was amazed at all the different mechanisms plants used to travel around and not stick to just one area. I did not expect the pointy spines of plants to allow them to grip
