Observation of mitosis in Onion root tips Answer the following question to its full explanation: 1. What is Cytokinesis? Compare and contrast cytokinesis between plant and animal cells. Cytokinesis is the last step in cell division, where the cytoplasm divide and the two daughter cells appear. In Animals, the cytokinesis processes occurs through cleavage. Firstly, in the old metaphase plate position, a cleavage furrow is formed. On each sides of the furrow, a contractile ring formed of actin…

Polyploidy refers to the individual with presence of more than two sets of chromosomes (3n, 4n, 5n, etc.) (Soltis et al., 2009) as sporophyte. Polyploids may have arisen as the result of nondisjunction during meiosis or may be generated when chromosomes are dividing properly in mitosis and meiosis, but the cytokinesis does not follow. Polyploidy can be classified into two: polysomic polyploidy (autopolyploidy) and disomic polyploidy (allopolyploidy) (Stebbins, 1951). Autopolyploidy comes from…

Organelles in the Cell Cells are the smallest structural unit of all organs and organ systems. They are essential to life. Both animal species and plant species need cells to maintain life. Cells have many and are made up of many organelles that have specific jobs. Animal and plants cells are different, but mainly composed of the same things. Each organelle is significant to its cell, which are the building blocks of life. At the center of almost every cell is a dense organelle called the…

1. Write a summary of the article using your own words. Lichens are evolutionarily deep symbioses of nature that are widespread and diversed. It is recently discovered that in addition to being composed of fungus and alga, as known by many, lichens are also composed of varying amounts and species of basidiomycete yeast. This discovery is made when Dr. Spribille and his colleagues analyze two species of lichen that are similar in genetics of fungus and alga but different in appearance,…

Relationship between cells Cells contain organelles these are the basis of a cell it contains many organelles and is basically the same a human these cells are the basic blocks of life cells are microscopic and what makes up tissues. Tissues are visible to the naked eye and are what creates us there are four main types of tissue connective epithelial nervous and muscle. Tissue makes up organs these are the what run us humans and every other living thing these keep them alive and have many…

Running head: DIFFERENCES OF ANIMAL CELLS VS. PLANT CELLS Differences of Animal Cells Vs. Plant Cells Hosheni Lakeraj Hudson County Community College DIFFERENCES OF ANIMAL CELLS VS. PLANT CELLS A plant cell is a eukaryotic cell, which is basically a membrane-bound nucleus. The DNA is located in a plant cell which is contained in the nucleus. Along with having a nucleus, plant cells have membrane-bound organelles. These organelles are accountable for constructing hormones and…

There are three samples of observation. The first one is called Mitotic stages, the second one is called As 114d, and the third one is called Lily meiosis. Mitosis stages is animal cell. This sample is brown. It combined with two big parts of the cell. There are many small bubbles in first part. The sizes of bubbles inside the big bubble are random. They separate randomly. Some of them are stick together, and some of them are alone. The second part of the sample is white and brown. The second…

Based on evidence, if a Protist could “protest” and be reclassified into another kingdom, which Protist could you help make the most convincing argument? To begin with, “Protista kingdom is sometimes called the, “junk drawer kingdom,” for the classification of living things. (Art. 1) When an organism’s characteristics do not quite fit into the fungus, plant, or animal kingdoms, they get classified into the Protist kingdom.(Article 1)”When scientists can’t figure out where to put organisms…

Characteristics can classify organisms into 5 key groups called the 5 kingdoms: - Protoctista: These are mainly unicellular organisms that also have a nucleus. Some examples of protoctista are paramecium, amoeba and unicellular algae. -Prokaryotes: These are also unicellular organisms like protoctista but unlike them, they do not have a nucleus. An example of a Prokaryote is bacteria. Some prokaryotes are able to make their own food which makes them more self-sufficient. These types of…

Transport of proteins into the nucleus occurs via a channel called nuclear pore complex (NPC), which penetrates and spans the nuclear envelope, a double membrane that separates the nucleus from the cytoplasm. The outer nuclear membrane is continuous with the endoplasmic reticulum, hence giving a shorter pathway for proteins to enter the nucleus; inner nuclear membrane contains proteins acting as binding site for nuclear lamina, indirectly providing support for the NPC as the primary function of…
