‘Bacterial cells are heterotrophic and plant cells are autotrophic’
(a) Which organelle makes the plant cell autotrophic?
(b) Describe its structure.
(c) Name the other two types of this organelle.
Answers
Answer:
a) Chloroplast
b) The chloroplast has an inner and outer membrane with an empty intermediate space in between. Inside the chloroplast are stacks of thylakoids, called grana, as well as stroma, the dense fluid inside of the chloroplast. These thylakoids contain the chlorophyll that is necessary for the plant to go through photosynthesis.
c) There are two distinct regions present inside a chloroplast known as the grana and stroma.
Grana are made up of stacks of disc-shaped structures known as thylakoids. ...
Stroma is the homogenous matrix which contains grana and is similar to the cytoplasm in cells in which all the organelles are embedded.

Vaise ur answer is:
A. Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
B. 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
C. There are two distinct regions present inside a chloroplast known as the grana and stroma.
- Grana are made up of stacks of disc-shaped structures known as thylakoids.
- Stroma is the homogenous matrix which contains grana and is similar to the cytoplasm in cells in which all the organelles are embedded.
