Which of the following is a function of the Golgi apparatus quizlet?
what is the function of the golgi apparatus? process and bundle proteins and lipids as they are synthesized – makes complicated molecules.
What is a gene quizlet?
gene. The set of information that controls a trait; a segment of DNA on a chromosome that codes for a specific trait.
What is the basic unit of structure and function of all living things capable of performing life processes?
The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.
Which level of organization is common to all life forms?
Which level of organization is common to all life forms? cell.
What are vestigial structures?
A vestigial structure is a rudimentary biological structure that was not rudimentary in the ancestors of its bearer. Such a structure is interpreted by evolutionary biologists as a vestige of a homologous structure that was more fully functional and often larger in the ancestors of the organism in question.
What is unity and diversity of life?
Unity in the Diversity of Life There are genetic similarities within the DNA of organisms as different as bacteria and animals. Unity is also evident in many features of cell structure. Common ancestry means that all living things past, present, and future share an ancestor, and all descended from that one individual.
Which of the following is a property of life?
Properties of Life. All groups of living organisms share multiple key characteristics or functions: order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.
What consists of all the parts of the earth that are capable of supporting life?
biosphere, relatively thin life-supporting stratum of Earth's surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.
What is the function of Golgi apparatus?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
What is the role of lysosomes?
Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.
What is a gene psychology quizlet?
Genes. the biochemical units of heredity that make up the chromosomes; a segment of DNA capable of synthesizing a protein. Indentical twims. twins who develope from a single fertilized egg that splits in two. Fraternal twins.
What is a gene in Brainly?
Gene is the genetic material which is found in the cell's DNA. They contain the genetic information which is passed after the generation after generation from parent to offspring. The genetic information is very important for fingerprinting and other Disease diagnosis.
Why is cell the structural unit of life?
The body or structure of any living organism is made up of cells. These cells are also responsible for carrying out all the metabolic and regulatory functions in an organism. Due to these attributes, the cell is called the structural and functional unit of life. Was this answer helpful?
What is the basic structural unit of life?
the cell In anatomy, the basic structural unit of the body is the cell. All living organisms have cells, which start as the zygote — the single cell at the beginning of life, after a spermatazoon fertilizes an oocyte. In humans, the body has more than 200 different cell types.
What is organization of life?
A group of two or more organs that work together to perform a specific physiological function (e.g., the digestive system, the central nervous system). The highest level of organization; a complete living system capable of conducting all of life's biological processes. Previous/next navigation.
What is the structural and functional unit of all living organisms?
The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.
What is a analogous structure?
Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.
What is rudimentary structure?
Charles Darwin used the term rudimentary structure in humans corresponding to functional ancestral animals is a vestigial organ (a rudimentary structure in humans corresponding to a functional structure or organ in the lower animals).
What is the meaning of unity of life?
Repeated speciation occurs with the continual divergence of life forms from an ancestral cell through natural selection and evolution. Our shared cellular structures, nucleic acid, protein and metabolic chemistries (the 'unity' of life) supports our common ancestry with all life.
What is the diversity of life?
Biological diversity, or biodiversity, refers to all of the variety of life that exists on Earth. Biodiversity can be described and measured at three different levels: species, genetic, and ecosystem diversity. Species diversity refers to the number of different species in an ecosystem or on Earth as a whole.
What is required for life?
It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements.
Which of the following is the basic structural and functional unit of all living organisms?
The cell The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.
Which of the following contains all life on Earth?
The biosphere – this contains all living organisms and it is intimately related to the other three spheres: most living organisms require gases from the atmosphere, water from the hydrosphere and nutrients and minerals from the geosphere.
How does the biosphere support life on Earth?
The biosphere helps in recycling nutrients, like oxygen and nitrogen, to sustain life on Earth. Provide food or raw material. Every living thing needs food to survive; thus, the biosphere plays an important role in providing food to different animals and plants.
What is the function of mitochondria and Golgi bodies?
Mitochondria : It performs the function of respiration and provides the cell with energy. It is called the power house of cell. Golgi bodies : These collect and distribute substances made in cell, synthesis and secretions of many materials. Ribosomes : They help in the synthesis of proteins.
What do mitochondria do?
Definition. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
