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.

Which of these is a shortcoming of the Clean Water Act? A.) excludes drain pipes B.) excludes lakes, rivers and streams c.) excl
PtichkaEL [24]

Answer: Option C) "excludes agricultural runoff"

Explanation:

The Clean Water Act (CWA) established in 1972 is a federal law made in United States to address the adverse effect of water pollution. The act was aimed to maintain the physical, chemical, and biological integrity of the nation's waters.

A major shortcoming of the Clean Water Act (CWA) is agricultural runoff which is a nonpoint source (NPS) pollution. Large scale agriculture activities have an adverse impact on groundwater and surfacewater as they carry heavy fertilizer, pesticide and  water inputs.

The federal CWA establish water quality standards and total  maximum daily loads (TMDLs) to asses the pollution caused by agricultural water with the help of regulatory mechanisms.

Hence, the correct option C.
