Cellular Organelles

Front

What surrounds the nucleus and is composed of two membranes?

Back

Nuclear envelope/membrane.

Front

Where are lipid components of the cell membrane assembled, along with proteins and other materials that are exported from the cell?

Back

Endoplasmic Reticulum (rough & smooth).

Front

What gives eukaryotic cells their shape and internal organization, and is made up of microfilaments and microtubules?

Back

Cytoskeleton/centrioles.

Front

What captures energy from sunlight and converts it into chemical energy in a process called photosynthesis?

Back

Chloroplasts.

Front

What modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell?

Back

Golgi Apparatus.

Front

What is the function of the nuclear envelope?

Back

It protects the nucleus and regulates the passage of materials in and out of the nucleus.

Front

What are the two types of endoplasmic reticulum and their primary functions?

Back

Rough ER (involved in protein synthesis) and Smooth ER (involved in lipid synthesis and detoxification).

Front

What is the role of the cytoskeleton in eukaryotic cells?

Back

It provides structural support, helps maintain cell shape, and facilitates cell movement.

Front

What is the significance of chlorophyll in chloroplasts?

Back

Chlorophyll is the green pigment that captures light energy for photosynthesis.

Front

How does the Golgi Apparatus contribute to protein processing?

Back

It modifies proteins received from the ER, sorts them, and packages them for transport.
