Animal Cell Dbq Essay

For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.

The scientific method can be used to prove a theory. Is it is a true or false statement? Clearly explain your answer in a short paragraph. (5 points) False, the scientific method is limited to those phenomena which can be observed or measured. Due to the need to have completely controlled experiments to test a hypothesis, science cannot prove everything. Science is meant to give us a better understanding of the mysteries of the natural world. So with that being said science is good at explaining “how things work” but not necessarily for explaining “why do such things exist” or “for what purpose”.

Essentially, the nucleus is vital for the cell’s survival. The nucleus controls and gives instructions to all organelles and inhabitants of the cell(Doc. 2). It is a dense, ball shaped configuration that contains the DNA of the cell.

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

The main function of the Endoplasmic Reticulum is to produce, store and transport proteins and lipid to most of the cell organelles. The Endoplasmic Reticulum is a large organelle that looks like sheets of folded membranes.

The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and

The nucleus is enclosed in a nuclear membrane which has pores to allow RNA and proteins. The nucleus functions the activity in a plant cell and stores the plant’s DNA. (Plant Cell Anatomy, n.d.)

Could a country survive without a president? All of these questions answer are no. Just like the questions above, a cell couldn’t survive without a nucleus. I think the nucleus is the most important organelle. The nucleus is the control center of the whole cell.

In plants the cell membrane is surrounded by a cell wall. The cell wall is outside the cell membrane, and its purpose is to help the membrane protect and support the cell. Since the cell wall is very porous, water, oxygen,

The answer is B, lysosomes. The answer cannot be A because chloroplasts are responsible for functions within photosynthesis and do not contain hydrolytic enzymes to break down cellular components. Central vacuole, answer C, cannot be correct either because the central vacuole is responsible for holding substances such as water within plant cells, helping to support the structure of the cell. Peroxisome and glyoxysome (D and E) are also incorrect because peroxisomes are used primarily within oxidative reactions and glyoxysomes are responsible for converting

Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a

In regards to their basic structure, according to the SEER Training website, “cells consist of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.” (Training.seer.cancer.gov, 2017) This is true for animal cells however plant cells contain a fourth part which is known as the cell wall, it is located on the outside of the cell membrane and allows the cell to keep its rigid shape. It should also be known that there are types of cells that do not contain a nucleus, these are called prokaryotic cells and generally still have the same characteristics as cells that do have a nucleus which are known as eukaryotic cells. (Study.com, 2017) As seen in Figure 1 cells also contain organelles which keep the cell alive and allow it to function effectively.The cytoplasm of the cell which resides between the cell membrane and the nucleus is a gel-like liquid filling the inside of the cell. The cytoplasm allows the cell to have shape and allows the cell 's organelles to move around the cell as needed and function correctly. The nucleus is widely considered to be the control center or

Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.

The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population genetics," 2014). The conditions set up by the Hardy-Weinberg Law allow for variability (the existence of different alleles) and inheritance, but they eliminate natural selection ("SparkNotes: population genetics," 2014). The fact that no evolution occurs in a population meeting these conditions proves that evolution can only occur through natural selection ("SparkNotes: population genetics," 2014). The Hardy-Weinberg Law allows us to estimate the effect of selection pressures
