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
Bacteria
Animals
|
The _________ contains the cell's genetic material (in the form of DNA), and so controls the cell's activities.
Cell membrane
Cytoplasm
Nucleus
Mitochondria
|
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?
Mitochondria
Nucleus
Cell membrane
Ribosome
|
What is 'cytoplasm'?
A jelly-like material containing nutrients and salts, where chemical reactions take place
An organelle that makes proteins
An organelle that controls what passes in and out of the cell
The site of photosynthesis
|
The diagram above shows an animal cell.
What is the structure labelled X?
Ribosome
Cell membrane
Nucleus
Mitochondria
|
What is the role of the mitochondria?
|
The diagram above shows an animal cell.
What is the structure labelled X?
Nucleus
Ribosome
Cell membrane
Mitochondria
|
Which of the following are found in plant cells, but not in animals cells?
(Select all that apply)
Permanent Vacuole
Cell wall
Nucleus
Chloroplast
Ribosomes
Cell membrane
|
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
Cell wall
Chloroplast
Nucleus
|
Bacteria are classed as ___________ organisms.
prokaryotic
eukaryotic
|
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
Cytoplasm
Nucleus
