Leslie Banesa Lopez Professor Charles Hart Biol 1101L 10Sept. 2016 JAA Q #1: What is the species name of the model/study organism? A: The species name of the green house whitefly is Trialeurodes vaporariorum. Q #2: What is one piece of interesting information found in the introduction? A: The most interesting part I found in the introduction was that almost all entomopathogenic fungal products contain conidia (asexual spores of a fungi) as an active ingredient. This type of production takes…

“I'm super nervous to meet the coach today” she says. She drives to practice. She meets the coach Bob. She thinks in the head the coach is kinda like the chromosomes because they teach you information about softball and how to hit a softball and catch a ball. The chromosomes In the cell Helps direct cell activity and stores necessary information for building proteins. “We are going to run a baseline drill” the coach says. (The girl) says to her friends “ isn't the baseline a little bit like the…

Metaphase I (MI) (Assembly of meiotic apparatus) During Metaphase I, Chromosomes move together along the metaphase plate. DNA replication, repair spindle function, and chromosome segregation are controlled by regulatory mechanisms of spindle assembly checkpoints (Elledge, 1996). The cellular spindle apparatus includes the spindle microtubules, associated proteins, and any centrosomes or asters present at the spindle poles. The dynamic lengthening and shortening of spindle microtubules (Mitchison…

Paramecium is a single-celled protist from the Alveolate clade. They live in wet environments like lakes, ponds, streams, rivers, and puddles. The wet environment can even be inside of animal bodies and in moist soil. Paramecium are heterotrophs, meaning they eat other living or non-living things. They eat by trapping food inside of their oral grooves, which are basically mouths. They use cilia on their body to not only move, but also help capture their prey. When the food gets into the oral…

Mitosis is a part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, and each set ends up in its own nucleus. Mitosis is composed of several different components: Interphase, Prophase, Metaphase, Anaphase, and Telophase. Interphase is the stage that happens right before mitosis, this is where a typical cell spends most of its life. In the prophase stage of mitosis, the first stage of cell division, the chromosomes become visible as…

Every cell in the body has a nucleus. The nucleus is the largest organelle and is contained within a membrane. The nucleus contains the body’s genetic material, which directs the activities, like the brain of the cell. This is built from DNA and proteins called histones coiled together forming a fine network of threads called chromatin. When under the microscope the most prominent part of the cell is the nucleus. The most visible structure within the nucleus is the nucleolus, which is where…

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…

Mitochondrion are made of two membranes. The outer membrane covers the organelle and acts as a layer of skin, whereas the inner membrane constantly folds over and creates layered structures called Cristae (The constant folding increases the surface area of the organelle). And the fluid inside the organelle is called the matrix. The matrix carry the specific DNA and ribosomes for the mitochondria, because the organelle carries its own DNA. Site of aerobic respiration and provides energy (ATP) to…

We are began as a single cell, but by the time that we are an adult, we have trillion of cells in our body. This happen because our cells are constantly dividing and when they divide they make new cells. A group of cells form a tissue, a tissue form the organ, an organ compound the system of organ and then the individual. We all have this question, why our cells are dividing constantly? Cells divide to replace old or damaged cells, and also living organism can grow and reproduce. There are two…
