Question

What 2 eukaryotic cell features are found ony in autorophic cells?

Answer 1

this is from http://library.thinkquest.org/27819/ch3_...

and it at least partly answers your question:



Plastids are found only in eukaryotic autotrophs. The three different types are chloroplasts, chromoplasts, and leucoplasts.

Chloroplasts

Chloroplasts are green organelles (because they contain the green pigment chlorophyll) which have an outer membrane and a folded inner membrane.

A solution called the stroma fills the space inside of the inner membrane.

Within the chloroplast are stacks of flattened vesicles. The stacks are called grana, and the vesicles are known as thylakoids.

Photosynthesis occurs within the thylakoids of a chloroplast.

Chromoplasts

Chromoplasts are like chloroplasts, but they do not contain the green pigment chlorophyll.

The colored pigments in chromoplasts absorb different colors of light than chlorophyll does, allowing photosynthesis to occur in different lightning conditions.

Leucoplasts

Leucoplasts are colorless since they do not contain any pigments.

They store starch, proteins, and lipids, releasing them when the cell requires them
