Cell Structure
This lesson covers:
- The structure of animal, plant, and bacterial cells
- The function of each sub-cellular structure (organelle), such as ribosomes and mitochondria
Which of the following are Eukaryotes?
(Select all that apply)
Plants
Animals
Bacteria
|
The _________ contains the cell's genetic material (in the form of DNA), and so controls the cell's activities.
Nucleus
Mitochondria
Cell membrane
Cytoplasm
|
mitochondria / nuclei / ribosomes
The are where proteins are made. We sometimes call them the site of protein synthesis.
|

The diagram above shows an animal cell.
What is the structure labelled X?
Cell membrane
Nucleus
Ribosome
Mitochondria
|
What is 'cytoplasm'?
A jelly-like material containing nutrients and salts, where chemical reactions take place
An organelle that controls what passes in and out of the cell
The site of photosynthesis
An organelle that makes proteins
|

The diagram above shows an animal cell.
What is the structure labelled X?
Ribosome
Mitochondria
Cell membrane
Nucleus
|
What is the role of the mitochondria?
|

Which of the following are found in plant cells, but not in animals cells?
(Select all that apply)
Permanent Vacuole
Chloroplast
Nucleus
Ribosomes
Cell membrane
Cell wall
|
sun / wind / photosynthesis / phagocytosis / chlorophyll / auxin
Chloroplasts carry out the process of , which involves using light energy from the to make glucose.
The green pigment that absorbs the light energy is called . This is what makes plants green.
|
The is a large sac in the middle of the cell that contains a watery solution of sugars and salts (cell sap). It helps maintain the structure and shape of the cell.
|
The ___________ is made of cellulose. This makes it strong and allows it to maintain the shape of the cell.
Cell membrane
Nucleus
Chloroplast
Cell wall
|

Bacteria are classed as ___________ organisms.
eukaryotic
prokaryotic
|

In the image above, which structure is labelled A?
|
True or false? Bacteria have both a cell membrane and a cell wall.
True
False
|
Are bacterial cells larger or smaller than animal cells?
Larger
Smaller
|
multicellular / unicellular
Bacteria are (only consist of a single cell).
|
Which of the following are not found in bacteria?
Ribosomes
Cell wall
Nucleus
Cytoplasm
