The graphic shows the island of Krakatoa, which disintegrated in 1889, due to the largest volcanic eruption in recorded history.

In the century since the eruption, the island has re-formed from lava flows. The table above shows the number of species of various plant types that were found on the island over a 30 year period, since the island re-surfaced above the ocean in the 1950's. Which of these plants is likely to be a pioneer species?

As you can see in the table presented below, in the first few years after the eruption, there was a significant number of moss species present.
Pioneer species are species that are very resilient and first to inhabit new habitats or repopulate disrupted ones, so in this example, mosses are the most likely candidate for pioneer species.

Match the following terms and definitions.
nlexa [21]

Answer:

<em>1. Oblong cells with unevenly thickened walls for support in young stems  →</em>

<em>Collenchyma </em><em>.</em>

<em>2. a waxy substance covering most surface areas of plants; helps to retain water  → </em><em>Cuticle</em><em>. </em>

<em>3. The youthful, undifferentiated cells of root and shoot tips and other plant parts that produce new cells for growth  → </em><em>Meristem </em><em>.</em>

<em>4. The most common plant cell, found in practically all parts of the plant body; important for food production, food storage, lateral transport, and other life processes; an almost round cell in some tissues  → </em><em>Parenchyma</em><em> .</em>

<em>5. Dermal layer made of dead cork cells  → </em><em>Periderm</em><em> .</em>

<em>6. Tiny holes in a cell wall which allow the passage of chemicals between cells  → </em><em>Plasmodesmata</em><em>.</em>

Explanation:

<em>This all refers to tissues found in plant organisms.</em>

  • In plants, the colenchyma is a supporting tissue, composed mainly of elongated, irregularly walled living cells with a large amount of cellulose. Their composition and the way they are arranged - with longitudinal interlacing - give the tissue strength and resistance. It represents one of the three basic tissues of plants.
  • Cuticles of plant tissue are formed by an oily secretion from the epidermal cells, forming a waxy, impermeable and protective layer, which prevents the entry of foreign organisms and reduces the loss of water from the plant. The cuticles are mainly composed of cutin molecules associated with wax.
  • Meristematic tissue represents a group of undifferentiated cells with great capacity to multiply, differentiate and provide growth and development to a plant. It is a tissue with unlimited growth capacity, which allows the plant to always replace the damaged tissue and grow indefinitely.
  • Parenchyma of plant organisms are tissues that are found in most of these organisms, allowing multiple functions, such as the drying of substances, storage and photosynthesis. The parenchyma is generally formed by thin-walled living cells that can adapt to any vital function of plants.
  • Periderm constitutes the outer coating of a plant or bark, functionally replacing the epidermis. This tissue is located after the secondary phloem, and is composed of cork, specifically phellem, phellogen and phelloderm.
  • Plasmodesmata are a type of microscopic channel that crosses the plant wall, being a link for intercellular communication, as well as the transport of nutrients.

If a people consume more protein than their body needs, the excess protein is __________. excreted in their urine deaminated and
Andrews [41]

When you consume more protein than your body needs, the excess protein is used to provide your body with energy or turned into fat.

<h3>How is protein essential for the body?</h3>

The protein need for the body depends on the age, physical activities, development and changes. For all these processes, body need a large amount of protein.  Our body is at the phase of breaking and building muscles, so high amount of protein is not harmful. Excess amount of protein is stored in the body in form of fats and break down when need for body energy requirements. So if the amount is increase it will result in weight gain and body size.  

Even a high amount of proteins is healthy and safe, but massive increase in amount can cause harm to the body.  

Thus,harmful effects of massive amount of protein depend on patient health.
