Biology Plants Immune Systems Plants serve as the main source of nutrients for countless organisms such as fungi‚ protists‚ vertebrates‚ and insects. In comparison to humans‚ a plant’s “immune system” is insignificant. However‚ plants have adapted and evolved chemical‚ physical‚ and protein based mechanisms to protect themselves against invaders. A plant’s first line of defense against pathogens is their innate immunity. The “innate-immune system” is a non-specific immune system and responds

Lab Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences

Title: To examine an animal and cheek cell using a compound microscope Date: 25th September 2012 Lab Partner: xxxxxxxxxxxxx Objective: The main aim of this experiment was to prepare a wet mount of human cheek cells and a wet mount of plant cells and examine them both under a compound microscope. Introduction: Cells are the basic units of life which make up every structure in the human body. They are the smallest units which are living. All cells contain different organelles which

Plant-Animal Coevolution Evolution Charles Darwin gave what could be described as a loose definition of evolution when he wrote “descent with modification” (Darwin‚ 1859). Evolution is defined more specifically as a change in the genetic composition of a population‚ from generation to generation (Reece et al.‚ 2011). In this investigation into coevolution‚ in particular plant-animal coevolution‚ the adaptations and reasons for these adaptations in a specific example of plant-animal coevolution will

BIO 131 Lab #2 Drawings of Animal and Plant Cells Instructions: 1. Set up light microscope for use. Handle with care. 2. Obtain a slide of animal cells and observe first under low-power (4X)‚ then under medium power (10X)‚ then finally switch to high-power (40X). 3. Make careful observations of the structure of the cells. 4. Draw what you see under high power on a sheet of paper. Place your drawing in a circle measuring 10-15 cm. Use only pencil‚ draw neat lines‚ do not shade. The title

circulatory system includes the heart‚ blood vessels‚ and the blood. The circulatory system in humans is also known as the cardiovascular system. The main parts of the plant circulatory system are xylem and phloem. Humans and plants rely on their circulatory system a great deal. Plants and humans rely on their circulatory system to supply the body or plant with nutrients‚ humans to transport oxygen throughout the body‚ and plants to carry carbon dioxide throughout the body. The circulatory system in both

Seeing Similarities Between Plants and Animals As you look around outside‚ you may see birds perched in trees‚ frogs croaking on lily pads‚ and even dogs digging in the grass. Our world is filled with plants and animals‚ yet when a person thinks of the phrase ’plants and animal‚’ they automatically begin thinking about the differences between the two. As different as they may seem‚ plants and animals are very similar in the following areas: reproduction‚ human uses‚ and the requirement of water

Sullivan Period 3‚ Biology 11/18/2007 Plant Cell Paper Plant Cell The plant cell is seemingly less complicated then the animal cells. Having the necessary nucleus which holds the cells DNA and produces ribosomes that help in the synthesis of proteins. Surrounding the nucleus is the rough and smooth endoplasmic reticulum. The two help break down and store materials. Rough stores and transports synthesized proteins‚ while smooth stores and transports synthesized lipid‚ steroid hormones‚ and

Ankur upaadhyay gujarat board/combined science igcse.9998791839 india. Q.1 Explain transportation of water in plants. A.1 (1) Higher plants possess xylem which is associated with the transport of water. (2) Water absorbed by the root from the soil is transported to stem‚ branches‚ leaves and flowers. (3) The main structural components of the xylem responsible for the transport of water are tracheids and vessels. (4) As the root cells are directly in contact with soil‚they take up ions.due
