Both plant and animal cells contain a nucleus that contains a cell’s hereditary material. 3. Both plant and animal cells contain mitochondria, which supply energy to the cell 4. Both plant and animal cells contain ribosomes, organelles necessary for protein synthesis. 5.
The majority of the cells mass is composed of cytoplasm. The cytoplasm is a gel-like substance, which in typical cells is largely composed of water, with trace elements of protein, enzymes, amino acids and sugars. Supported within the cytoplasm are all of the cells internal components or organelle, the parts of a cell that define the cells nature and function. Organelle in eukaryotic cells are more numerous to the component parts of prokaryotes, though components and organelle such as ribosomes can be familiar to both. Ribosomes are responsible for assembling chains of amino acids to make protein.
Cytoplasm is located within the cell membrane and all cell types and contains all organelles and cell parts. Majority of all the important activities take place in the cytoplasm as cytoplasm consist of enzymes which are responsible for breaking down waste and also aid in metabolic activity. Nucleus: The nucleus is the control system of the cell. The nucleus contains the DNA of the cell. The function of the cell is to maintain the integrity of these genes and to control the activities of the cell by regulating the gene expression.
This energy is then in turn used by the cell to carry out various functions. Nucleus- The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. Nucleolus- This takes up around 25% of the volume of the nucleus. This structure is made up of proteins and ribonucleic acids (RNA). Its main function is to rewrite ribosomal RNA (rRNA) and combine it with proteins.
Animal cells tend to have fewer and larger Golgi apparatus. Plant cells can contain as many as several hundred smaller versions. The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles. Depending on the contents these are despatched to one of three destinations: Cytoplasm-The cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cell.
In this task I will outline the functions of the main cell components. Which consists of the Cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum (smooth and rough), golgi apparatus and lysosome. Cells are the structural and functional units of all living organisms. Cells can take in nutrients, change these nutrients into energy and can carry out particular functions, and reproduce them if needed. Mitochondria Mitochondria Nucleus Nucleus Lysosome Lysosome Golgi apparatus Golgi apparatus Cell membrane Cell membrane Endoplasmic reticulum (Smooth and rough) Endoplasmic reticulum (Smooth and rough) Cytoplasm Cytoplasm Cell Membrane A cell membrane of the cell.
The nucleus also contains one or more nucleoli which contribute to the manufacturing of ribosome’s using information from its own DNA. The
The nucleus regulates all cell activity and is bounded by a double membrane called the nuclear envelope, this membrane separates the contents of the nucleus from the cytoplasm. The Nucleus have two major functions. It stores the cell’s hereditary material, or DNA and it co-ordinates the cell’s activites, which include metabolism, growth, protein synthesis, and reproduction (cell division). ‘Mitochondria are the cell’s power producers’ Bailey, About.com. They convert energy into forms that are usable by the cell.
Many chemical reactions are carried out in the cytoplasm. Glycogen and melanin are found in the cytoplasm. Organelles: Organelles are different components of a cell and have a distinct structure and their own functions. They can be likened to miniature organs. Organelles include mitochondria, Iysosomes, the Golgi apparatus and the endoplasmic reticulum.
Lab 4 The Cell: Anatomy and Divison Anatomy of the composite cell 1.Define the following terms: organelle: "small organs"; are the metabolic machinery of the cell, and that are highly organized to carry out specific functions for the cell as a whole. Cell: the structural and functional unit of all living things, is a complete entity. 2.Although cells have differences that reflect their specific functions in the body, what functions do they have in common? Growing, reproducing, and responding to a stimulus are common functioning characteristics amongst all cells. In addition, all cells can maintain their boundaries, metabolize, digest nutrients, and dispose wastes.
