Vascular tissue

with lignin are also present. Simple pits are also present. It is abundant in vascular tissue of angiosperm such as flowering plants. Sclerenchyma is important in supporting tissues in plants. Sclereids account for the hardness in seeds of the plant. Fibre plays a role in transporting water in the plants. Xylem is located in the middle section of the of a plant stem. It can be found close with other transport tissues in plants such as phloem –which transports sugars and amino acids in the plant

Objectives • Analyze plants as an example of a multicellular organism with specialized structures at the cellular, tissue and system levels (STS and Knowledge Outcome #3) o Describe how the cells of the leaf system have a variety of specialized structures and functions; i.e., epidermis including guard cells, palisade tissue cells, spongy tissue cells, and phloem and xylem vascular tissue cells to support the process of photosynthesis o Explain and investigate the gas exchange system in plants; i.e.

et al. 2010). Plant tissue culture has been widely employed for to efficiently and rapidly multiply and preserve genetic stability of the plant material. Plant tissue culture has offered a viable solution for the production of phytochemicals through mass production of consistent plant material for physiological characterization and analysis of active ingredients (Arora 2010). It has been reported that the production of secondary metabolites is higher in differentiated tissues than intact plants (Smith

Meta Description: Learn more how nonvascular and vascular plants work and get the chance to improve your gardening skills in dealing these plants. What's the Difference Between Vascular and Nonvascular Plants? 8 Differences To Know Have you noticed that some plants don't really need repotting? Or, have you noticed that some plants just need more water than the others? If you don't, then perhaps you should revisit Kingdom Plantae– which happens to be everywhere, by the way. Every plant you encounter

do not form a monophyletic group (a clade). There favorable habitat is in moist soil and or tree bark which allows them to germinate and grow into gametophytes. They generally form into ground hugging carpet, because of the bryophytes lack of vascular tissue which is needed to transport water and nutrients in long distances. The thin structure allows bryophyte organs to

the root cortex, surrounds the vascular cylinder. It is the passage of minerals from the cortex into the vascular tissue. The stem has a system of nodes where leaves are attached. They have a waxy coating (epidermis) that prevents water loss. The stem and the roots are the 2 main axes in a vascular plant. Fluids are transported between the roots and the shoots through the stem by the phloem and xylem. Leaves are the main photosynthetic

The common land plants are thought to have originated 450-500 million years ago from a group of freshwater green algae called charophytes (Domozych). These algae emerged on land and thus spawned the first plants, bryophytes. Bryophytes are non-vascular plants who first appeared 354-409 million years ago in the Devonian period, and are only found on land (Evolution). Since they lived on land, they had little support and relied on their cells’ turgor pressure to keep them upright (Evolution). Turgor

nonvascular plants which include liverworts, hornworts, and mosses. The other two which are the focus of this paper are vascular seedless plants and vascular seed plants. The difference between vascular and nonvascular plants is that vascular plants have vascular tissue which enables them to grow up and be bigger than nonvascular plants. The difference between seed and seedless vascular plants is the presence of a seed. A seed is defined by the 10th Edition of Campbell Biology as “an adaption of some

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

response to injury. An injury to soft tissue can arise from numerous sources. Physical traumas such as sprain, strain or contusion are the most common. However, there could also be injuries from viral or bacterial infection, chemical, or heat injury. Trauma can cause direct damage to cells that are in the immediate area of injury, causing bleeding. From there, the bleeding causes a line of events in the inflammatory process that promote healing the injuries tissue. Stage 1: The Inflammatory Response
