    Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

    Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is

    Internal Structure Of A Plant PLANT CELL STRUCTURE Plant cells are classed as eukaryotes organisms‚ because they have a membrane enclosed nuclei and organelles. Here is a diagram of a plant cell;  Cytoplasm Most chemical reactions take place here. It helps the cell maintain it’s shape. Nucleus The nucleus has two main roles. Firstly it contains all the cells genetic information. Secondly it coordinates the cell’s activities‚ which include growth‚ intermediary metabolism‚ protein synthesis

    PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

Meristematic cells – embryonic‚ undifferentiated and capable of cell division • Apical meristem – located at root and shoot ends • Lateral meristem – run parallel to the long axis of roots and stems – where somatic cells undergo mitosis 2.) Differentiated/Permanent Cells – specialized in structure and usually do not divide • Simple Permanent Tissue – dermal tissue system and ground tissue system › Dermal tissue system – outer surfaces of

    Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They

    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
