Cell Structure and Function

This is a picture of:

• Prokaryotic Cell

• Eukaryotic Cell

Answer explanation

The image depicts a eukaryotic cell, characterized by a defined nucleus and membrane-bound organelles, distinguishing it from prokaryotic cells, which lack these features.

Where is DNA stored in a eukaryotic cell?

• Cytoplasm

• Mitochondria

• Ribosomes

• Nucleus

Answer explanation

In eukaryotic cells, DNA is primarily stored in the nucleus, which serves as the control center for the cell. Other options like mitochondria contain some DNA, but the nucleus is the main storage site.

What kind of cell?

• Prokaryote

• Both

• Neither

• Eukaryote

Answer explanation

Prokaryotes are single-celled organisms without a nucleus, such as bacteria. The question asks for a type of cell, and since the correct answer is 'Prokaryote', it indicates that the cell in question lacks a defined nucleus.

What kind of cell?

• Prokaryote

• Eukaryote

• Both

Answer explanation

Eukaryotes are complex cells with a nucleus and organelles, unlike prokaryotes, which lack these features. Therefore, the correct answer is Eukaryote.

What kind of cell?

• Eukaryote

• Prokaryote

• Both

Answer explanation

The correct answer is 'Prokaryote' because prokaryotic cells are simpler and do not have a nucleus, unlike eukaryotic cells which do. Prokaryotes include bacteria and archaea.

Plant cells and animal cells

• are both prokaryotic

• are both eukaryotic

• do not have a nucleus

• do not have DNA

Answer explanation

Plant cells and animal cells are both eukaryotic, meaning they have a true nucleus and membrane-bound organelles. The other options are incorrect as prokaryotic cells lack a nucleus and DNA is present in both cell types.

The function of the mitochondria is

• is to make proteins for the cell.

• transport materials in and out of the cell.

• break down waste products for the cell.

• break down glucose through cellular respiration and make energy for the cell.

Answer explanation

The mitochondria are known as the powerhouse of the cell, as they break down glucose through cellular respiration to produce energy in the form of ATP, which is essential for various cellular functions.

Check the three major differences between a plant cell and an animal cell.

• cell wall

• mitochondria

• large central vacuole

• chloroplasts

Answer explanation

Plant cells have a cell wall, large central vacuole, and chloroplasts, which are absent in animal cells. These structures provide support, storage, and photosynthesis capabilities, highlighting key differences between the two cell types.
