What is a chloroplast structure?
Structure of Chloroplasts Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane. Between the outer and inner membrane is the intermembrane space approximately 10-20 nm wide. The space within the inner membrane is the stroma, the dense fluid within the chloroplast.
How do you identify a chloroplast?
Chloroplasts are a type of plastid—a round, oval, or disk-shaped body that is involved in the synthesis and storage of foodstuffs. Chloroplasts are distinguished from other types of plastids by their green colour, which results from the presence of two pigments, chlorophyll a and chlorophyll b.
How do you identify organelles?
Most of the organelles are so small that they can only be identified on TEM images of organelles. While shape and size help distinguish some organelles, it is usually necessary to see the interior structure to be sure what type of organelle is shown.
What is meant by electron micrograph?
noun. a photograph or image of a specimen taken using an electron microscope.
What are the types of micrograph?
There are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image.
Which is the cell organelle responsible for photosynthesis draw well Labelled diagram of it?
chloroplasts
3) Typical chloroplasts are disc shaped and consist of three membranes. 4) The third layer that forms stacked sac-like structures is called grana….

Which of the cell organelle consists of chloroplast?
Answer: Chloroplasts and Other Plastids. Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.
In which animal chloroplast is present?
Chloroplasts are present in the cells of all green tissues of plants and algae. Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants.
What is the electron micrograph of plastids?
The Electron Micrograph of Plastids: This is an electron-micrograph of plastid or chloroplast, which is an integral component of all green plant leaves and is characterized by following features (Fig. 15 & 16): (1) They may be spheroidal, ovoid, stellate or collar shaped and differ in size and number in different cells.
What should I look for in electron micrographs?
Also, be sure to observe any electron micrographs which are made available in the laboratory by the instructor. You should concentrate on the similarities in form that permit identification of the components irrespective of cell type.
What are the features of plastid or chloroplast?
This is an electron-micrograph of plastid or chloroplast, which is an integral component of all green plant leaves and is characterized by following features (Fig. 15 & 16): (1) They may be spheroidal, ovoid, stellate or collar shaped and differ in size and number in different cells.
What is the electron micrograph of endoplasmic reticulum?
The Electron Micrograph of Endoplasmic Reticulum: It is an electron micrograph of endoplasmic reticulum and is characterized by following features (Fig. 11 & 12): (1) It was discovered and named by Porter (1948).
