Characteristics of Mitochondria (i) The mitochondria are sausage-shaped or cylindrical having a diameter of 0.2-1.0 µm and average 0.5 µm and length 1.0-4.1 µm. (ii) Each mitochondrion is a double membrane bound structure. (iii) The inner compartment is called the matrix.

What are 5 characteristics of mitochondria?

Because of this double-membraned organization there are five distinct parts to a mitochondrion:
  • The outer mitochondrial membrane
  • The intermembrane space (the space between the outer and inner membranes)
  • The inner mitochondrial membrane
  • The cristae space (formed by infoldings of the inner membrane) and.

What are the characteristics of the mitochondria?

Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm. In addition to producing energy mitochondria store calcium for cell signaling activities generate heat and mediate cell growth and death.

What is the difference between mitochondria and chloroplasts quizlet?

In mitochondria ATP is produced as a result of oxidation and foodstuffs and is used as an energy source for metabolic processes. In chloroplasts ATP is produced as a result of harvesting energy from light. In chloroplasts the ATP is used in the fixation of CO2 into sugars.

What is the mitochondria function?

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).

What are the characteristic structural features of chloroplasts?

The chloroplast is enveloped by an inner and outer membrane with an intermediate space between. The chloroplast contains smaller parts inside called Thylakoids. These thylakoids are arranged like stacks of coins which are called grana. There may be 40-80 grana in the matrix of the chloroplast.

Which of the following is a characteristic of chloroplasts that suggests that they might have?

46) Which of the following is a characteristic of chloroplasts that suggests that they might have evolved from free-living bacteria? Chloroplasts have their own DNA. The earliest cells detectable in fossils were different from the cells in animals plants fungi and protists living today.

What is the function of the chloroplasts?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so they sustain life on Earth.

What are the characteristics of mitochondria Class 9?

Structure of Mitochondria

Its size ranges from 0.5 to 1.0 micrometre in diameter. The structure comprises an outer membrane an inner membrane and a gel-like material called the matrix. The outer membrane and the inner membrane are made of proteins and phospholipid layers separated by the intermembrane space.

What are the differences between chloroplast and the mitochondria?

The main difference between chloroplast and mitochondria is their functions chloroplasts are responsible for the production of sugars with the aid of sunlight in a process called photosynthesis whereas mitochondria are the powerhouses of the cell which break down sugar in order to capture energy in a process called …

Which of the following are similarities between mitochondria and chloroplast quizlet?

What similarities do the mitochondria and chloroplasts share? Both membrane bound organelles have their own DNA and help make energy available to the cell.

What is the difference between mitochondria and mitochondria?

The only difference between mitochondria and mitochondrion is that mitochondrion is singular and mitochondria is the plural form of the word.

What is the function of mitochondria and chloroplast?

Mitochondria are the “powerhouses” of the cell breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

What are two functions of mitochondria?

They generate the majority of our adenosine triphosphate (ATP) the energy currency of the cell. Mitochondria are also involved in other tasks such as signaling between cells and cell death otherwise known as apoptosis.

How do mitochondria make energy?

Mitochondria are organelles – ‘small organs’ within each cell. They produce energy in the form of a molecule called ATP (adenosine triphosphate) which gets used throughout the cell to power the different jobs it has to do. … As they do so energy is extracted and transferred into ATP.

What is the function and structure of chloroplast?

Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O2) by photolysis of water. Produces ATP – Adenosine triphosphate by the process of photosynthesis.

How does the structure of chloroplast relate to its function?

The structure of the chloroplast is adapted to the function it performs: Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation. Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption. …

How chloroplast is adapted to its function?

Many grana large surface area for photosynthetic pigments electron carriers and ATP synthase enzymes. Photosynthetic pigments are arranged into structures called photosystems allows maximum absorption of light energy.

What are two characteristics about mitochondria and chloroplast that make it similar to prokaryotic bacteria cells?

– Chloroplasts and mitochondria are prokaryotic. They have their own genes on a small circular chromosome but no nucleus. This chromosome has little non-coding DNA similar to those of bacteria. Chloroplasts and mitochondria also make some of their own proteins from their genes.

What do you think about the relation of mitochondria and chloroplast with evolution of eukaryotes from prokaryotes which theory is involved?

The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission.

What is a characteristic of mitochondria that suggests that they might have evolved from free-living bacteria?

Mitochondria have their own circular DNA chromosome that carries genes similar to those expressed by bacteria. Mitochondria also have special ribosomes and transfer RNAs that resemble these components in prokaryotes. These features all support that mitochondria were once free-living prokaryotes.

What is a characteristic of mitochondria and chloroplast that supports the Endosymbiotic theory?

Which of the following is a characteristic of mitochondria and chloroplasts that supports the endosymbiotic theory? Both contain DNA molecules. Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic processes.

What characteristics of mitochondria and chloroplasts give support to endosymbiosis?

Explanation: Bacteria a prokaryote has circular DNA as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).

What are the two main functions of the chloroplasts?

The main role of chloroplasts is to conduct photosynthesis. They also carry out functions like fatty acid and amino acid synthesis.

Why chloroplast is the most important organelle?

Chloroplasts play an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms.
