Which of the following refers to flattened sac like structures found inside of the chloroplast?

the flattened disc like sac in chloroplast is called thylakoid. Thylakoids float freely within the chloroplast’s stroma. Chlorophyll is embedded directly in the thylakoid membrane, which encloses the watery material known as the thylakoid lumen.

What are the individual coin shaped disks inside the chloroplast called?

Thylakoids float freely within the chloroplast’s stroma in a place called the thylakoid space. In higher plants, they form a structure called a granum that resembles a stack of coins 10 to 20 high.

What do thylakoids contain?

Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The grana are connected to other stacks by simple membranes (lamellae) within the stroma, the fluid proteinaceous portion containing the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.

What is the function of thylakoids?

Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.

Why do plant cells have chloroplasts and animal cells do not?

However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.

What is the main function of thylakoids?

The principal functions of thylakoids are the trapping of light energy and the transduction of this energy into the chemical energy forms, ATP and NADPH. During this process, water is oxidized and oxygen is released.

What is the purpose of thylakoids?

Do lysosomes have a double membrane?

Lysosomes: are single membrane bound organelles rich in digestive enzymes, help in breakdown of large molecules like proteins, polysaccharides, lipids and nucleic acids. These are bound with double membrane, outer smooth and inner folded.

Where are chlorophyll sacs suspended in the stroma?

The system is suspended in the stroma. It is a collection of membranous sacs called thylakoids. The green coloured pigments called chlorophyll are found in the thylakoid membranes. It is the sight for the process of light-dependent reactions of the photosynthesis process.

Where are chlorophyll molecules found in a chloropslast?

In a chloroplast, chlorophyll molecules that capture light energy are found in the internal, or inner membrane, which is also called the _______ membrane. thylakoid Which of the following are the three stages of photosynthesis in plants?

How are the thylakoids arranged in the chloroplast?

The thylakoids are arranged in stacks known as grana and each granum contains around 10-20 thylakoids. It is a colourless, alkaline, aqueous, protein-rich fluid present within the inner membrane of the chloroplast present surrounding the grana.

How does the stroma lamellae function in the chloroplast?

Stroma lamellae function by connecting the stacks of thylakoid sacs. The chloroplast structure consists of the following parts: It comprises inner and outer lipid bilayer membranes.
