Question

What is Chromoplasm?

Answer 1

Hint: Chromoplasm is present in the periphery protoplasm of cyanobacteria. The chromoplasm is rich in thylakoids. The chromoplasm contains chlorophyll and accessory pigments and also some kind of stored substances. Thus, peripheral thylakoid is the appropriate place where chromoplasm can be found. It is the major component of cell structure of cyanobacteria. Chloroplast DNA is not composed of true histones in red algae or proteins that are tightly packed in each chloroplast.

Complete answer:
As we know, Chloroplasts are usually found in green plants and algae. Chloroplasts are often found in photosynthetic tissues which are not green in color, such as brown blades of giant kelp or the red leaves of certain plants. Chloroplast is the pigment which is found on plastid types. The chloroplasts have chlorophyll and carotenoid pigments that are responsible for trapping light essential for photosynthesis.
Like in bacteria, the cell of cyanobacteria contains a layer called a sheath or plasma membrane or cytoplasm. Chromoplasm is a substance that forms a nucleus around the cell during cell division. Chromo-meaning the color part and plasm- the membrane covering. So, protoplasm which stains with dyes are called chromoplasm.
It also defines the pigmented, peripheral protoplasm of blue-green algae and contains chlorophyll and carotenoids. All the carotenoids and chlorophyll are integral parts of the chloroplast which provide pigmentation to the plant.

Note:
So, as we discussed about chromoplast, Majority of the chloroplast of green plants are found in the mesophyll cells of leaves. Chloroplasts are lens-shaped, oval, spherical or ribbon shaped organelles. their number varies from $1$ per cell. Example – Chlamydomonas, green alga. Also, leucoplast is the plastid which is a non-pigmented organelle. without grana, chloroplasts were found to be present in bundle sheath cells.
