Plant morphology

Germination is a process that seeds undergo when the correct exterior conditions are met and water is introduced, allowing seeds to begin the process of growing into a fully mature plant. When enough water is near the seed it enters the cell by osmosis, specifically a type of osmosis called imbibition when the seeds are in a dormant state. The flow of the water into the seed reinstates a hypotonic environment.This recreates turgor pressure inside the cells causing the cell walls to be rigid,…

Pycnopodia Helianthoides, which is known as the sunflower seastar, is an extraordinary star fish found in the northeast Pacific. It is one of the largest sea stars in the world, and has a maximum arm-span of 1m (Lambert, 2001). This intertidal organism has many amazing traits that most other sea stars do not possess. I will discuss these unique characteristics throughout my essay. Sunflower seastars have 16 to 24 limbs and are radially symmetrical. It is also the heaviest known sea star on the…

how fast a plant grows? A seed is “the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.” (Dictionary.com) Seeds go through a process, called germination, to grow. The seed first has its roots break out and grab hold of the soil. After the roots have a hold of the soil a small plant will sprout from the ground. All plants go through the germination process. (How do Seeds Sprout?) The hypothesis is: If the weight of a seed affects the rate the plant…

is found in plants, that not only controls the plant’s growth and development, but also germination of seeds, lengthening of the internode of the stem, expansion of leaves, floral initiation, and the development of flowers and fruit. It is composed of C19H22O6. Plants are known to only produce a small amount of this particular type of hormone. My colleagues and I wanted to form an experiment to find out if the concentration of gibberellic acid would affect the height of pea plants. We…

introduced in the substrate there is a higher amount of salt concentration on the outside of the cellular membrane. This is what is known as a hypertonic solution meaning there are more solutes on the outside of the cellular membrane. A requirement for plants to successfully germinate is the presence of water. The water activates enzymes within the seed that trigger the…

Germination is the transition from mature embryos to an actual plant containing both a root and a shoot. This involves having a visible root and shoot as well as cotyledon elongation. (Attree 1990) Once the seed germinates, both a root and a shoot forms, and the seed capsule is pushed up, out of the dirt by the stem before it falls off. The different treatments used in this study affected the overall germination of the Picea mariana seeds. The seeds which were only treated with distilled water…

Some plants don’t need water as a necessity to grow,while others need all the water and care they can get get to sprout.When working on the CGLA Community Garden PBL project,various groups learned that the amount of light exposure does in fact take away from the moisture levels.Also, that a plant not having enough moisture does impact the plant 's growth. According to Bodie V. Pennisi., a extension floriculture specialist (v.1), a lot of light time does affect your plant’s moisture…

Role of Ethylene in Plants The development of the plants involves the progressive and recessive birth and death of their parts such as shoots, roots, leaves, flowers and buds. The tree shape could be examined by taking into account the numbers of parts that determine the longevity and final outcomes. The outcomes of buds are determined by their location on the tree. While many factors are involve in the regulation of this developmental pattern. Ethylene plays an important role in the…

How big do avocado trees get Title: Size and Height of Full-Grown Avocado Trees Meta description: Avocado trees grow large, but you can grow smaller ones by pruning or planting a dwarf variety. Click here for details on avocado tree size and height. Most types of avocado tree naturally grow to a large size and height. Because of their large size, avocado trees need plenty of room around them to thrive and produce fruit. However, there are two ways of growing smaller avocado trees. --The…

The plant part I chose to observe was an acorn. Although I was uncertain about what I was supposed to find, I took mental notes of the acorn and its location. The acorn, light brown in color, wearing a rigid little dark brown cap, had just fallen off a tree by the Agriculture Sciences building. It seemed abandoned in a sense, just left to lie on the concrete, among dead decaying leaves, and other fallen acorns. It looked as if it had been left to die. As people were walking by they began to kick…
